About the VHD Format
The Microsoft VHD file format specifies a virtual machine hard disk that can reside on a native host file system encapsulated within a single file. The format is used by Virtual PC 2004 and Virtual Server 2005, and the format will be used by a future version of Microsoft Windows Server that includes hypervisor-based virtualization technology. Beyond that, the VHD format is broadly applicable, because it is agnostic to the virtualization technology, host operating system, or guest operating system with which it is used.

Customers and partners who invest the VHD file format will have a clear path forward to future Windows virtualization technologies. In addition, Microsoft plans to design its systems management tools around the VHD file format for improved patching and manageability.

Top of page Potential Uses of the VHD Format The ability to directly modify a virtual machine’s hard disk from a host server supports many interesting applications that may be of interest to customers. These include:

• Moving files between a VHD and the host file system • Backup and recovery • Antivirus and security • Image management and patching • Disk conversion (physical to virtual, and so on) • Life-cycle management and provisioning

Is it a disc? a vinyl record? or a cassette?
Seems the terminology is a bit wonky with vinyl VHD movie discs... ok, so they are vinyl like a record, flat like a record but contain video like 'some records', but is not a record and a record for some reason is not a disc? but the VHD is a cassette? or is it a cassette because it is a disc in a caddy like encasing? is a cassette not a tape? but it can be a disc? or a record?

NTSC
Anyone know about the color encodinng used on such disks? I used to have an NTSC TV set with a switch to play PAL/SECAM VHD disks. I don't believe that my TV decoded PAL or SECAM, so it would have to have NTSC signals at 625/50 rates. Gah4 (talk) 04:58, 26 March 2020 (UTC)
