Abstract

Abstract Disc recorder for recording information is comprised of a plurality of disc faces and correspondingly provided heads for recording information on the disc faces, the heads are connected to corresponding recording/reproducing circuits controlled by a control device, the disc faces, the heads and the recording/reproducing circuits constitute recording/reproducing channels. The disc recorder performs recording and/or reproducing operations by utilizing 2 or more of the recording/reproducing channels concurrently where an information unit to be processed in the recording/reproducing channels and recorded on every sector on the disc faces, is adopted to be a logical block unit having a control signal region and a data region. Further feature of the invention is that the control device has an output signal line connected to a host system.
