Abstract

Abstract A record disc for storing a composite signal that includes segments of audio information and corresponding segments of video information. The disc contains a succession of consecutively arranged substantially circular and concentrical information tracks including audio information-containing tracks and separate video information-containing tracks. Each of the audio information-containing tracks has at least a portion of an audio information segment stored therein in time-compressed digital data format, and each of the audio information segments includes packets of digital data interleaved with conventional video synchronizing signals, with adjacent audio information packets representing a continuous portion of the stored audio information segment. Each of the video information-containing tracks has a video information segment stored therein in real time, and each video information segment contains a single video frame in conventional video format including conventional video synchonizing signals.
