Abstract
A method and apparatus for regulating the speed of a multitrack audiotape machine while recording audio from a multitrack audiotape onto a videotape. The speed of the audiotape machine is regulated by correlating a video synchronization signal previously recorded onto the audiotape with a video synchronization signal controlling the videotape recorder during the recording. Highly accurate synchronization between the two machines is achieved. This allows for the transfer of multiple audio tracks from the multitrack audiotape onto the videotape and then onto multiple laser videodiscs, such that during playback of the multiple laser videodiscs, the laser videodisc players can be synchronized with each other.
