Disk reproducing apparatus and reproducing method thereof
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.
1. A disk reproducing apparatus for reproducing a video and sound signal recorded on an optical disk, comprising:
reproducing device that reproduces the video and sound signal recorded on the optical disk in a predetermined low-speed mode;
first retry device that retries reading of the video and sound signal of a sector in which a read error occurs in the predetermined first speed mode when the read error of the video and sound signal occurs during the reproduction of the optical disk by the reproducing device;
second retry device that increases a rotational speed of the optical disk to retry reading of the video and sound signal of a sector in which a read error occurs in a predetermined second speed mode when the read error of the video and sound signal occurs during the retry of the reading of the video and sound signal by the first retry device, and
reproducing control device that returns the rotational speed of the optical disk to the original rotational speed to reproduce the video and sound signal recorded on the optical disk in the predetermined first speed mode when the video and sound signal of a sector in which a read error occurs can be read by the retry of the reading of the video and sound signal by the second retry device.
2. A disk reproducing apparatus for reproducing a video and sound signal recorded on an optical disk, comprising:
reproducing device that reproduces the video and sound signal recorded on the optical disk;
first retry device that retrying reading of the video and sound signal when a read error of the video and sound signal occurs during the reproduction of the optical disk by the reproducing device;
second retry device that increases a rotational speed of the optical disk to retry reading of the video and sound signal when a read error of the video and sound signal occurs during the retry of the reading of the video and sound signal by the first retry device, and
reproducing control device that returns the rotational speed of the optical disk to the original rotational speed to reproduce the video and sound signal recorded on the optical disk when the video and sound signal can be read by the retry of the reading of the video and sound signal by the second retry device.
