What is claimed is: 1. An optical disk player having an operative defocus prevention device, wherein the application of the detection signal is blocked after a predetermined period of time from the start of transition of the playback position from the audio area to the video area. (2) means for reproducing an optical disk having an audio area and a video area; a means for detecting scratches on the optical disk and generating a detection signal; and an out-of-focus prevention device that operates upon application of the detection signal. What is claimed is: 1. An optical disc player comprising: an optical disc player, wherein application of the detection signal is stopped after the rotational speed of the spindle motor reaches a predetermined value.
