Abstract
The reading position of a first reading head jumps when it is located in a vertical blanking period section of a video disc and the reading position of a second reading head jumps when it is located outside a predetermined portion of the vertical blanking period section in which a PCM audio signal is recorded. An output of the first reading head that is produced by reading sections other than the vertical blanking period section is employed as a video reading signal, and an output of the second reading head that is produced by reading the vertical blanking period section is employed as an audio reading signal.
