OPTICAL DISK REPRODUCING DEVICE

PROBLEM TO BE SOLVED: To prevent large vibration so as to feel with palpation caused by eccentric center of gravity of a disk, a strange noise and the matter that normal read becomes impossible by deciding a rotational speed when the disk is reproduced based on acceleration when the rotation of the disk is accelerated. SOLUTION: When an optical disk 1 with a large eccentric center of gravity amount is rotated, the vibration becomes large, and further, the more the eccentric center of gravity amount becomes large, the more the rotation acceleration time of the disk 1 becomes long. Then, the number of revolution of the optical disk 1 at a reproducing time are set answering to the time that the rotational speed of a motor part 3 arrives at 5,000 rpm from 3,000 rpm. A control circuit 11 makes the number of revolution 3,000 rpm equivalent to 6-fold speed, and reads TOC information on the optical disk 1, and then, makes 5,000 rpm equivalent to 10-fold speed being a regular reproducing speed, and measures its acceleration time to set in an answering reproducing speed. Thus, the vibration caused by the eccentric center of gravity amount of the disk 1 is made within the allowable range.
