Electromechanical device that records, stores on a videotape cassette, and plays back on a TV set recorded images and sound. The first commercial VCRs were marketed by Sony Corp. in 1969. VCRs are used to record broadcast TV programs for later viewing and to play commercially recorded cassettes. They have from two to seven tape heads that read and inscribe video and audio tracks on magnetic tape. Home movies can be made with a camcorder system, a VCR connected to a simple video camera.
