Talk:Quantum Corporation

About the notes
Those notes at the bottom are a great addition. Hydrargyrum, if you come back by this page, can you see if there's any details I missed? I wrote most of this article, based on having read Quantum's patents and doing research in old magazines and the New York Times, and I'm wondering if there's any other inside information that would be useful. (Oh, and did the Shrewsbury designs continue using a 68k processor even after the Quantum takeover? I remember taking apart an old DSP series drive and seeing a 68030 in it, and I know the Milpitas designs more or less universally used NEC 78k CPUs.) -lee 14:48, 11 April 2006 (UTC)
 * To add to this, it looks like we've had a visit from someone in Shrewsbury... -lee 23:44, 12 May 2006 (UTC)

 * It's been a while since I visited this article, Lee, but I see that much of what I'd footnoted on January 28, 2006 has been pretty much diluted into oblivion. It's interesting to step through the article history as (ex-)Shrewsbury people have chimed in and put their spin on events.  Laughable.  I worked in a technical capacity in the Milpitas, California facility until late 2001, but we were acutely aware of the behind-the-scenes politics, and bitter rivalries among the executives.  The low end SCSI disk drive products coming out of Milpitas were simpler, ran cooler and quieter, had better reliability and actually outperformed many of the high end disk drives designed in Shrewsbury, with faster seek times and better data rates.  Moreover, they typically made it into production on schedule and hit the "sweet spot" in the market; in other words, they made money for the company, while a number of Shrewsbury-designed products were late to market, losing out on market share.  I can understand why some folks from Shrewsbury might still feel embarrassed and would like to rewrite history here.  The article, as it stands now, makes it seem that the company was split into DLT and HDD divisions (with separate "tracking stocks") due to the "fantastic demand" for DLT drives due to Y2K jitters.  While it's true that there was a huge upsurge in tape drive sales in 1999, it's also true that the market flopped the next year along with the unrealized Y2K fears and bursting of the dot-com bubble.  What really happened was that Quantum execs were getting ready to put the HDD portion on the chopping block (along with that pesky HDD division president who was gunning for the CEO's job), which, in fact happened in 2001.  To dispel any doubts that the whole thing was baked in well in advance, the ex-Quantum employees who were terminated by Maxtor in 2001 were paid their severance out of Quantum funds. It's likely that the decision of which products and groups were to be retained and which were to be terminated was also decided before the HDD division was acquired by Maxtor on April 1, 2001.  How else would they have been able to budget for the severance packages that were to be paid by the former employer?  It was also interesting to see how they axed groups of just under 200 people each month, month after month, until some 2000 workers were gone from the combined Maxtor and Quantum company; by keeping it under 200 it avoided the need for making public announcements of the layoffs.  Milpitas had the better disk drive engineers and Shrewsbury had the better politicians, which isn't entirely surprising, since the disk drive was born in San Jose, California and Silicon Valley was the epicenter of disk drive development for over 30 years.  In any case, I'd say Quantum committed suicide due in large part to management egos and internal politics, more than anything else.
 * To answer your question above, Shrewsbury favored the Motorola 68K processor family, while the late 1990s Milpitas SCSI designs built by MKE used the NEC 78k, the latter having originally been designed for use in photocopy machines. NEC had to make some critical changes to the die so they could win a design-in by Quantum, since MKE in Japan fastidiously avoided buying non-Japanese components, even to the point of forcing Quantum to completely redesign a product and having to rewrite firmware from scratch.  There was no meaningful push-back from Quantum management; whatever MKE wanted, MKE usually got, frequently to the detriment of product quality.  At our request, NEC added Flash memory to the CPU die, having had no prior expertise in Flash technology.  The first year of production from NEC saw drives whose firmware would evaporate in 7-8 months after a drive was built; fortunately, they achieved acceptable data retention in the Flash by the time our disk drive was ready for production.  Due to political wrangling between Shrewsbury and Milpitas, the Milpitas SCSI designs were forced to migrate to the same CPUs and code base used by the Shrewsbury HDD teams in 2000, so another code base had to be discarded, a setback for the Milpitas designers.  The last hard drive design on which I participated was gerrymandered beyond belief by mid-2001, but at that point we no longer cared, as our team's termination date had already been announced.  Ironically, Shrewsbury was tasked with completing our design, and I later heard they finally got it into production a year late, far too late to make a profit.  They won all the political battles, but lost the war in the end.  It was rather ugly at times. &mdash;QuicksilverT @ 06:40, 11 July 2010 (UTC) (a.k.a. "Hydrargyrum")

The Optical System
A couple of comments regarding the Quantum optical system discussed in the "Origins" section...

 "they put a diffraction grating on the head arm" 

It wasn't a diffraction grating, at least they didn't intend it to be one! Quantum referred to that part in their documentation as a "glass scale", and it was attached to the actuator arm, which moved the head (and thus the scale) back and forth across the disk surface.

The scale was a small, light, very thin piece of glass whose surface had an array of narrow chromium plated lines separated by equal widths of clear glass. The pitch of the lines matched the track pitch on the disk.

Immediately below the scale was a glass reticle, under which was a matching quad photo detector array. The reticle had four openings, one above each cell of the photo array, and each opening was plated with a pattern of lines that matched those on the scale. The phase relationship between the lines in each of the four windows (relative to the scale) was 0°, 90º, 180º and 270º. This allowed for quadrature detection of exact track position and direction of head movement.

The optical system also contained an IR LED that sent light through the scale then through the reticle, to be detected on the quad photo detector. During a seek the system merely needed to count the number of track crossings seen by the detector array to know when it was approaching the desired track. And to then use the quadrature data to place and maintain the head precisely on that track.

 "the optical system was deemed too slow to be competitive and was discontinued" 

Actually, that is not quite accurate. As originally introduced, the optical servo system was an elegant and cost-effective solution. However, as track densities increased, and consequently the line pitch on the scale increased, there came a point where the "scale" had indeed turned into a diffraction grating!!!

The Quantum optical system relied on the light acting as if you were drawing it in a ray tracing program and not as a true electro-magnetic wave function that could "bend" around sharp corners. As soon as the diffracted light became a significant percentage of the light going through the scale, the system lost its ability to accurately seek and follow a track.

By the time of the demise of the optical system, track pitch (and thus line pitch on the scale) was 13um, while the wavelength of the IR emitter was a mere 0.9um. Even though the IR wavelength was more than an order of magnitude smaller than the scale openings, still, about half the light energy was being strongly diffracted. That was the limit the Quantum optical system could stand.

In other words, the optical system died because of snowballing track density requirements. (Although, if it had not been for the diffraction problems, it's true that speed would have eventually caught up to and killed Quantum's optical system.) The diffraction problem was not the only design problem the optical system faced, but it was the one that dealt it the death blow.

The last Quantum drives using the optical system were the Gemini series of drives. Even then, the parts cost for the entire optical system was about $5.25!

I have no idea how useful the above information is to the principle author of the Quantum article, but feel free to use as much or as little of it as you see fit. I'm quite confident there is nothing I wrote above that is any longer proprietary.

 * Thanks for the extra information on this. You're right; I did fudge a few things in the original article, since I was working from memory and back in 2003 or so, Wikipedia was still pretty lax about citing sources. If I goofed on something, feel free to go ahead and change it. (Also, I should note that what I know about these drives came mainly from Quantum's patents, some of which are very nearly full technical manuals, and from actually taking a few drives apart. I've never actually worked for Quantum or any of their successors, I just had something of an obsession with their drives back in the 1990s -- mainly fueled by glowing reviews in MacUser, of all things -- and had to know what made them tick. :D)


 * PS. I actually do have a Gemini here (the LPS120AT, to be specific), and it still works fine with no bad sectors despite being 16 years old. It's not of much use in an era where they practically put 1GB USB keys in cereal boxes, but it's still impressive. -lee 23:56, 25 May 2007 (UTC)

Thanks for your response, Lee. The observations I made above were minor and hyper-technical in nature, so I'll only add a note to the main article to click on the discussion page for more detail.

One extra technical note, the Quantum optical servo system was the brain child of their head of Advanced R&D, Bill Moon, a certifiable genius and a real kind gentleman, to boot.

I got a kick out of your comment about how you learned about the drives through disassembling them, that's the mark of a very healthy mind! I learned from spending four years at Quantum as an engineer.

About those "glowing reviews in MacUser" that you mention, Apple was easily Quantum's single biggest HDD customer for almost the entire time Quantum was in the HDD business.

Boot 00:19, 26 May 2007 (UTC)


 * Ah yes, Apple OEM drives. Those were fun. The oldest Apple OEM drive I've run into so far was a mid-1980s Q280 (most likely a pull from a Mac II!) that, sadly, no longer worked when I got it (it'd either been dropped hard or degaussed). I've also seen some Apple OEM drives that were, to put it mildly, VERY weird. A few machines in the late 1980s/early 1990s had those oddball Sony drives in them (AFAIK the only hard drive Sony ever made) -- I think Quantum actually sued Sony over that, since the optical servo system was in them). There was also the MiniScribe 20MB that was in the SE, but MiniScribe was always strange. (I also hear tell the people that designed Conner's first drives were ex-MiniScribe, which explains a lot.)


 * And yeah, Bill Moon, I know about him. His name's all over Quantum's early patents. He sounds like he would have been an interesting guy to meet. 66.93.100.114 03:42, 26 May 2007 (UTC)
 * Oh, oops, that was me; I forgot to log in. -lee 03:44, 26 May 2007 (UTC)

I moved the discussion of the optical feature into a separate section. Much of the text here was useful! I hope it makes sense. -- Austin Murphy 18:29, 27 August 2007 (UTC)

What to do about the notes
I have some problems with the Notes section in this article:
 * It might be getting long. We're up to 7 footnotes now, and it's starting to look messy.
 * Parts of it read like an advertisement. Ever since Shrewsbury passed by, it's read like a pep rally for their team, complete with boasting about how Storage Review likes their drive (which is well and good, but not terribly encyclopedic) and how great things are going to be under Seagate (noting, of course, that Seagate doesn't even mention the Atlas 15k on their site now). I propose trimming out the bits that read like that, and possibly removing the bits about their little turf war with Milpitas unless someone else (Boot Hill, Quicksilver?) can add more about it.
 * Reliable sources. All of this is based on primary sources and anecdotes from people that were there. I really wish we had a better way of vetting all this, but no one's written a book about it yet...

Comments? -lee 11:51, 11 June 2007 (UTC)


 * I agree that the notes are taking over the page, but I think they hold the best parts of the article. My opinion is that they should be rolled into the main article.  We can probably tone down the "rah-rah" part.  Some of it may make more sense in the Seagate article or even a DEC Storage article.  Primary sources are not a problem as long as they are identified.  Why not make a little primary sources section on this talk page?  -- Austin Murphy 19:07, 11 June 2007 (UTC)
 * Hmm. That may not be so bad, then. -lee 04:16, 27 June 2007 (UTC)

I deleted the notes after moving a lot of the info into the article. It could still be improved a lot, but I think this is an improvement. -- Austin Murphy 18:21, 27 August 2007 (UTC)
 * It looks a lot better than it did. Thanks for the help! -lee 14:15, 30 August 2007 (UTC)

Manufacturing in Ireland
I think I recall some Quantum hard disks from the mid-90s allegedly being made in Ireland. this article also suggests that they have or had some operation in Dundalk. Anyone have any more info? --Zilog Jones 21:45, 12 June 2007 (UTC)
 * This is totally anecdotal, but I had one of the Ireland-made disks some time ago (I forget now which exact model it was, but it was form the ST/SE era, about 1997.) -lee 04:17, 27 June 2007 (UTC)
 * I think it was just a repair facility and a warehouse. The articles I can find are kind of vague.  It appears that production is currently in Panang, Malaysia. -- Austin Murphy 16:51, 27 August 2007 (UTC)
 * Yes, Quantum/Matsushita had a factory in Ireland and there were "Made in Ireland" Quantum drives. The factory was actually run by Matsushita to build drives for Quantum, just like the Matsushita factories in Japan and Singapore. See here (Matsushita to open a plant in Ireland to build drives for Quantum), here (same), here (SEC statement clearly saying that Quantum drives are built in Ireland), here (SEC statement saying MKE stopped producing drives in Ireland), here (Matsushita closing Ireland drive plant). There is a Facebook page run by ex-Quantum Dundalk employees. Quantum (the tape drive business) shut down the Dundalk site in 2006, see Facebook page for documents. This was a Quantum-run repair/configuration/logistics facility in Dundalk that kept going for some time after the drive production was stopped. In summary, there was both a repair facility/warehouse in Dundalk and a drive production facility. Codegen86 (talk) 09:20, 9 June 2021 (UTC)
 * Forgot to mention that Quantum's own documentation shows how to identify drives made in Ireland based on their serial number. Codegen86 (talk) 12:41, 9 June 2021 (UTC)
 * Good investigation work, albeit over a decade from the original query. - Indefensible (talk) 23:44, 2 August 2021 (UTC)

Updating Quantum Article
Hi, I work at Quantum and noticed the description at the beginning of the article is out of date. I thought it would help to add some of the technologies Quantum is currently offering. I may also be able to add some historical perspective having originally joined back in 2000.

More than just tape drives, Quantum also sells tape library, disk-based virtual tape library or VTL systems, data de-duplication technology, and storage management software.

Let me know if I can help with any specific verifications and I may be able to find source materials (as long as it is not company confidential or copyrighted material).

Quantum Fireball, ugh.
...and after we have enough time to sort through this mess, I think it should be considered that basically every consumer Quantum in the mid to late 90's is a "Fireball". Ugh. --144.131.105.68 (talk) 14:28, 31 October 2010 (UTC)

Disagree with recent revision
The latest revision involved streamlining the section regarding Quantum's hard disk products. Apparently "streamlining" meant "remove it completely", and I disagree with it. I think the list of Quantum's hard disk products was perhaps the most important part of the article because that is the most well-known part of their corporate existance, and it offered an excellent database of their hard disk products and when they were released. Anyone care to agree/disagree?

COI Request for Guidance/Updating Question
I am looking for some advice/guidance and help answering a question, as well as making changes to the Quantum Page. I'm working with Quantum Corporation directly and they'd like to assist in updating the company Wikipedia page so that it abides by Wikipedia's guidelines and is an updated, accurate resource for anyone looking for information on the company. While I have previously submitted edit requests to some of what is already existing on the page, I know that the page was flagged in Sept. 2016 due to needing citations and for needing some cleanup to help it read more neutral.

I've done some research to identify some of the missing sources but am having trouble finding anything, likely due to the age of some of the information. I understand that Wikipedia functions as an Encyclopedia and should contain as much historical background information as possible, but I'm curious at what point information needing citations should/would be removed if sources can't be identified? Is there an editor who does not have a COI who may have some time to either help answer this question or help get the page to a better place? I know there is more current information available on the company that is missing from the page and I'd love to be able to help get this page properly sourced and updated.

Interested in learning more about the editing process and hope to hear/learn from some experienced editors! Thanks in advance for your time. JessicaWinski (talk) 19:16, 25 January 2017 (UTC)

COI Request: Additional Sources
I am submitting additional sources to help clean up the page as part of my work with Golin for Quantum Corporation. Additional edit requests for the page are above, but my understanding is that the page needs to be cleaned up as-is before our other edit requests to help update the page can be addressed.

Much of the information on the page missing sources is quite old, so sources were hard to come by. I believe that the below sources are reliable sources, but hope to have an editor without a COI review. I am happy to add any approved sources to the page once an editor without at COI has reviewed them and provided feedback, if it is easier for the editor. Please let me know if there are any questions or concerns about any of the citations provided below. Thanks in advance for the help!

Proposing Updates to Intro Paragraph
Currently: Quantum Corporation is a manufacturer of data storage devices and systems, including tape drive and disk-based systems. The company's headquarters is in San Jose, California. From its founding in 1980 until 2001, it was also a major disk storage manufacturer (usually second-place in market share behind Seagate), and was based in Milpitas, California. Quantum sold its hard disk drive business to Maxtor in 2001 and now focuses on integrated storage systems.

Suggested: Quantum Corporation provides integrated storage technology and services designed to enable customers to capture, create and share digital content. Quantum’s storage platforms are used to preserve and protect high-resolution video, imagery, industrial IoT and other types of unstructured data. The company’s headquarters is in San Jose, California.

I am also proposing that we show that finance was secured before the delisting comment: 2018 - Quantum Corp. announced the successful completion of a refinance of its current debt facilities. Citation:

I am suggesting these changes as a Quantum employee, for full disclosure. @FlightTalk can you help me make these changes? Picard091488 (talk) 17:53, 15 July 2019 (UTC)

CARES Act
Originally called "Abuse of CARES Act", the section was renamed to remove derogatory words. Additionally, "With a head count of ~800 employees, this would be equivalent of receiving over $12,000 per employee. The program was setup to support small business, however, Quantum drew almost 10 times per employee compared to other corporations." was removed, as it's conjecture and does not have a source or citation. — Preceding unsigned comment added by Picard091488 (talk • contribs) 17:48, 23 April 2020 (UTC)


 * Hi, I've partially reverted your edit to reinstate the criticism against Quantum since I believe it is grounded in the evidence provided by the cited NPR article (particularly as it describes the "vast majority of the loans handed out [as] considerably smaller, averaging about $250,000") . I've removed the references to a lower headcount and tagged the new information as Citation_needed. Feel free to remove the "citation needed" tag once citations to the NAICS, PPP eligibility exemptions, and the 550 headcount have been added. As noted in, you should seek Consensus before making changes as an employee to avoid Conflict of interest, especially if new facts are being added without clear citations. You might find the WP:RFC process useful for drawing attention to proposed edits on an article. Thanks for editing Wikipedia. Harley Watson (talk) 13:20, 25 March 2021 (UTC)

As of writing, this section is still in a pretty sorry state. Seems to me like the edit war has reached a botched non-resolution. I believe the issues are as follows.

1. Should the section title include the word 'Abuse'. Based on the single source linked to, I believe not. The article does not clearly indict the applicants themselves; rather it is critical of the government's policy or implementation: "the Trump administration's failure to allocate funds properly". In any case it should be 'Abuse of PPP' not 'Abuse of CARES Act'.

2. The '10 times higher' sentence is wrong (according to the NPR source), and the SBA industry code section has no citation.

3. The section appears to include original research authored by an account with a small number of related edits, which have been repeatedly reverted, and has since fled the scene.

4. General discussion or criticism of the PPP seems better placed on its own page; Quantum was one of thousands of applicants and (based on the NPR source) not of singular significance.

I propose to delete this section entirely. Citruswinter (talk) 15:32, 15 August 2021 (UTC)

Close connection flag
This flag is outdated (2019) and the primary sources that came from a Quantum website have been removed and/or replaced. Planning to remove the flag unless anyone else would like to weigh in. Tincoaster (talk) 17:47, 22 June 2022 (UTC)
