A CDE Definition
A digital, handheld device that is used to record short reminders. Very lightweight and typically using AAA batteries, such devices use flash memory to hold up to 100 messages and more. Messages can be retrieved sequentially or by direct access by message number. See microcassette.
A smaller version of the analog audio cassette. Introduced in 1969 by Olympus, microcassettes were widely used for recording dictation and messages in a pocket-sized device. Because the recording speed is slower and the tape is thinner than an audio cassette, a tiny microcassette can hold 30 minutes per side. A dictation feature of many devices was variable playback speed.
Microcassettes were also used to record messages in some telephone answering machines; however, in the 1990s, tape-based recorders of all kinds evolved into solid state devices. See voice recorder, audio cassette and cassette.
