Abstract
A video disk player generates an error control signal according to the difference between write and read addresses, and causes a read clock to be synchronized in phase with a write clock, on the basis of the error control signal upon reception of an external video signal instead of a video signal produced by playing a video disk, thereby always keeping constant the difference between both addresses.
