A video and sound signal recorded on an optical disk is reproduced and when a read error of the video and sound signal occurs during the reproduction of the optical disk, reading of the video and sound signal is retried and when a read error of the video and sound signal occurs during the retry of the reading of the video and sound signal, a rotational speed of the optical disk is increased to retry reading of the video and sound signal and when the video and sound signal can be read by the retry of the reading of the video and sound signal, the rotational speed of the optical disk is returned to the original rotational speed and the video and sound signal recorded on the optical disk is reproduced.
