Picocassette

Picocassette is an audio storage medium introduced by Dictaphone in collaboration with JVC in 1985.

The Picocassette was introduced to compete with the Microcassette, introduced by Olympus, and the Mini-Cassette, by Philips.

It is approximately half the size of the previous Microcassette, and was intended for highly portable dictation devices.

[1] With a tape speed of 9 mm/s, each cassette could hold up to 60 minutes of dictation,[2] 30 minutes per side.

The widest dimension of the picocassette was near 42 mm (1.7 in).
