Videocassette recorder. The home videocassette recorder (VCR) operates after a cassette has been inserted into the loading door (upper left). As the tape is fed through the machine, two magnetic recording heads, located on opposite sides of a rotating drum, rapidly trace a series of diagonal recording tracks (as shown at greatly reduced speed in the animation, lower left). This helical-scan method allows the wide range of frequencies present in a video signal to be recorded on a slow-moving tape.
