FIELD: physics, computation hardware.
SUBSTANCE: invention relates to computers. Proposed device comprises a readout and disc playback system. Said readout is configured to readout data from particular region of data carrier. Control data comprises data on playback speed and data on maximum speed of data transmission complying with required application. Said data on playback speed differs from that on maximum transmission speed while playback speed making an adequate speed of main data playback. Disc playback system is configured to be controlled by aforesaid readout and data carrier as far as the drive is concerned and servo control to playback main data written in main data region in response to data on playback speed and/or data on transmission maximum speed.
EFFECT: ruled out faults at playback caused by absence of data on audio-video flow transmission speed.
