(VideoCassette Recorder) A videotape recording and playback machine that houses both supply and takeup reels of tape in a convenient removable package. The most ubiquitous VCR format was the half-inch VHS videocassette. One inch tape cassettes were used in studios for professional mastering, and Sony's 3/4" U-matic tape cassettes were used in corporate training before VHS tapes became popular.
