Cassette tape

The Compact Cassette or Musicassette (MC), also commonly called the cassette tape, audio cassette, or simply tape or cassette is an analog magnetic tape recording format for audio recording and playback. It was developed by Philips in Hasselt, Belgium, and introduced in September 1963. Compact Cassettes come in two forms, either already containing content as a prerecorded cassette (Musicassette), or as a fully recordable "blank" cassette. Both forms are reversible by the user.
