CA 2022192

An optical disk recording/reproducing device in accordance with the present invention has a controller that, during the recording, performs the rotation control of the optical disk in Constant Linear Velocity according to reproduced signals of pre-recorded information that was preliminary recorded on the optical disk, during the reproduction, performs the rotation control according to reproduced signals of recorded information, and when the rotation control based on the reproduced signals of the recorded information is infeasible, switches the rotation control and performs the rotation control based on the reproduced signals of the pre-recorded information during the reproduction also. As a result, a suitable and appropriate CLV control may be executed during the recording and during the reproduction.
