摘要 |
An apparatus and method for recording both a television picture signal and a digital data signal onto one track of a video disk. The digital data is divided into fixed length blocks.

Therefore, after a predetermined delay, the modulated digital data and modulated television picture signals are added and recorded on the video disk.
