Thr Cassette Tape is a magnetic tape recording format for audio recording and playback released by Philips in 1962. Compact cassettes come in two forms, either already containing content as a pre-recorded cassette, or as a fully recordable "blank" cassette. It was designed originally for dictation machines, but improvements in fidelity led the Compact Cassette to supplant the Stereo 8-track cartridge and reel-to-reel tape recording in most non-professional applications. Its uses ranged from portable audio to home recording to data storage for early microcomputers. Between the early 1970s and the early 2000s, the cassette was one of the two most common formats for prerecorded music, first alongside the LP record and later the compact disc (CD).
