Tape Recorder
An audio TAPE RECORDER, TAPE DECK or TAPE MACHINE is an analog audio storage device that records and plays back sounds, including articulated voices, usually using magnetic tape , either wound on a reel or in a cassette , for storage. In its present-day form, it records a fluctuating signal by moving the tape across a tape head that polarizes the magnetic domains in the tape in proportion to the audio signal. Tape-recording devices include reel-to-reel tape deck and the cassette deck . The use of magnetic tape for sound recording originated around 1930. Magnetizable tape revolutionized both the radio broadcast and music recording industries. It gave artists and producers the power to record and re-record audio with minimal loss in quality as well as edit and rearrange recordings with ease. The alternative recording technologies of the era, transcription discs and wire recorders , could not provide anywhere near this level of quality and functionality
