ABSTRACT:
A variable transfer rate data reproduction system is provided which performs a reproduction operation and a reproduction inhibit operation cyclically to reproduce data recorded on a recording disc. A pickup traces a spiral track formed on the recording disc during the reproduction operation and is also controlled to continue to trace a following portion of the track over a plurality of track turns during the reproduction inhibit operation without a track jump. Upon resumption of the reproduction operation, the pickup jumps over the plurality of tracks to return back to a portion of the track where the reproduction operation has been Interrupted previously. This results in decreased mechanical stress acting on mechanical parts for moving the pickup.
