Multisided record

A multisided record is a type of vinyl record that has more than one groove per side. This technique allows hidden tracks to be encoded on LPs, 45 rpms and 78 rpms. On a disc that has a multi-groove, whether the listener plays the main track or the hidden track depends on where the stylus is cued.

The most frequently cited example of a multiple-groove record is Monty Python's infamous "three-sided" Matching Tie and Handkerchief album, issued in 1973. One side of the album (both sides were labeled "Side 2") was "normal"; the other contained a pair of grooves, each of which held different material (later pressings of the record did not include the double groove).

Another memorable example of a multiple-groove recording was the 1980 flexi disc entitled It's a Super-Spectacular Day issued by MAD magazine. The disc played a standard introductory section about the start of a wonderful, "super-spectacular" day, then produced one of several different comedic "bad" endings to that day, involving such topics as alien abduction, zits, street violence, and the horrors of a visiting mother-in-law.

Other uses to which multiple-groove recordings have been put include various games (such as horse races or mystery games) where the outcome is determined by which of the record's multiple grooves is played.

Examples
Some records to have incorporated this feature, include:-


 * So-called Puzzle Plates produced by the Gramophone Company in London in 1898 and 1899: these were discs with two interleaved tracks, issued as E5504, 9290, 9296. Their most famous was a three-track Puzzle Plate (9317) recorded in January 1901 and given as the prize for a competition, for which several master recordings had to be made, distinguished by suffix letters against the catalogue number.
 * One of the earliest examples of a three-track side was a 1901 Pre-Dog Victor A-821 Fortune Telling Record. This is a multi-Track disc with three recording tracks that go all the way through the record. It is titled "Fortune Telling Puzzle Record a song and two Fortunes, See if you can find them."
 * "The Fortune Teller Song," a 1951 single by the Fontane Sisters (RCA Victor 4106), contained four different versions of the song, each with a different ending.
 * "Laura Scudder's Magic Record," a 1969 record produced by George Garabedian's Mark 56 Records and offered as a promotional give-away by Laura Scudder's Potato Chips. Each side contained three different songs that would play at random depending upon the drop of the stylus.  https://www.discogs.com/Various-Laura-Scudders-Magic-Record/release/10469094
