A microcassette is a type of small magnetic tape recording technology that was popular in the 1990s and 2000s. However, as technology has advanced, microcassettes have become increasingly obsolete. Modern alternatives to microcassettes include digital voice recorders, smartphone voice memo apps, and cloud-based recording services. Other synonyms for microcassette include mini cassette, pocket cassette, and memo cassette. Each of these terms refers to a similar type of small audio cassette designed for recording voice messages or other short audio notes. While microcassettes may no longer be widely used, they represent an important chapter in the evolution of audio recording technology.
