Abstract
PURPOSE:To promote the reliability of a reproducing signal by providing a 1st disk rotational control means for such a rotational control that a number of revolutions of an optical disk should correspond with a target number of revolutions and a 2nd disk rotational control means for such a rotational control that a linear speed of the optical disk should correspond with a fixed linear speed set by the 1st disk rotational control means. CONSTITUTION:In a signal recording part of the optical disk 1 under its reproducing operation, the linear speed of the optical disk detected based on a mark signal included in the reproducing signal is controlled by the 2nd disk rotational control means 8 to be correspondent to the fixed linear speed set by the 1st disk rotational control means 10. On the other hand, in a non-recording part of the signal, the number of revolutions of the optical disk 1 detected by a number of revolutions detecting means 5 is controlled by the 1st disk rotational control means 10 to be correspondent to the target number of revolutions settled according to a tracking radius position on the optical disk 1 to obtain a fixed linear speed. By this method, a reliable speed control is performed, and a good quality reproducing signal can hence be obtained.
