(Battery life also was a problem, because the high bias currents required by Type IV tape, combined with the state of battery technology at the time, meant that brand-new alkaline batteries might give out in two hours when the unit was in recording mode.) "Standard" microcassettes are still used in the underground-music circuits for recording and distributing experimental music and field recordings/ sound collage, mostly because of their lo-fi qualities. īoth of these "high-fidelity" microcassette recorders and the special Type IV blanks they required were relatively expensive and of limited availability, so the system was not widely adopted and Olympus phased them out after two years on the market. This was an attempt by Olympus to cash in on the burgeoning Walkman market one model, the Olympus SR-11, had a built-in radio and offered a stereo tie-clip microphone as an accessory, which made the unit somewhat popular with concert-goers who wanted to record the concerts they attended without drawing attention to themselves with larger, bulkier full-sized cassette recorders.
coated with pure metal particles rather than oxide) tape were sold. For the latter purpose, devices for recording in stereo were produced in 1982 and, for higher fidelity, microcassettes using Type IV ("metal", i.e. Microcassettes have also been used in computer data storage and to record music. In particular, they are commonly used in dictation machines and answering machines. Microcassettes have mostly been used for recording voice. For the programmable calculators of the HP-41-series (from 1979, r.), there was a magnetic tape storage device. Microcassettes were sometimes also used for storing digital data. The latter is far more widely used than the other two types, which were rather rare.

History Three devices using microcassettes: By using thinner tape and half or a quarter the tape speed, microcassettes can offer comparable recording time to the compact cassette but in a smaller package. It has the same width of magnetic tape as the Compact Cassette but in a cassette roughly one quarter the size.
The Microcassette (often written generically as microcassette) is an audio storage medium, introduced by Olympus in 1969. A Microcassette is significantly smaller than a Compact Cassette
