ABSTRACT:
An apparatus and method for reproducing and after-recording digital signals in slant recording tracks sequentially arranged on a recording medium includes a recording subsystem for recording digital signals in each of the slant tracks and a reproducing subsystem for reproducing digital signals therefrom. The recording and reproducing subsystems include one or more recording and/or reproducing heads for scanning each of the tracks for recording and reproducing digital data therein. A tracking control subsystem controls tracking of the heads with respect to the tracks in a reproducing mode based upon tracking signals recorded both in first and second tracking signal recording areas of the tracks located at initial and final scan positions, respectively, of each track. In an after-recording mode, the tracking control subsystem utilizes tracking signals recorded in only one of the tracking signal recording areas while recording digital signals in a first sub information recording area proximal to the area from which the utilized tracking signals have been obtained.
