SYNCHRONIZATION METHOD AND APPARATUS FOR DISC RECORDERS

摘要

A method and apparatus for synchronizing a video source, such as a television camera, with a recording disc wherein prerecorded clock signals are provided on the disc on a first track and master clock signals are recorded on a second track with the recorded master clock signals being utilized in the generation of drive and synchronizing signals for the video source so that the video source and the disc are directly synchronized and the prerecorded clock signals are compared with an external source of clock signals for controlling the speed of the disc.
