Pocket Disc

Pocket Disc was a type of flexidisc, made by Americom Corporation and experimented with in the late 1960s, small enough (4 in (10 cm) in diameter) to be carried in one's pocket or shipped in an envelope and not as fragile as a standard record, but playable on the standard manual-only phonograph or record player (at 33+1⁄3 rpm).

The PocketDisc was cheaper than the Hip Pocket Records manufactured by Philco that sold them to be played on portable record players, which were specially created for the disks.

[1] Artists who appeared on these disks included Aretha Franklin, Steppenwolf, Jimi Hendrix, Neil Diamond, The Five Americans, The Doors, Sonny and Cher, Merrilee Rush, and Joan Baez.

This meant songs like The Beatles' "Hey Jude" could not be played in their entirety.

[4] The disks were first released on September 15, 1968[5] and test marketed in several major cities in the United States, but did not catch on.
