Abstract
A video disk recording method and the recorded disk in which a video signal is frequency-multiplexed with a digital data signal into respective frames which are asynchronous to each other. A time code is recorded in both types of frames. The time is incremented periodically but the period in one of the types of frames is occasionally varied to compensate for the asynchronism.
