ABSTRACT:
In a reproducing apparatus for an optical disc recorded at a constant linear velocity (CLV), so as to increase the reproducing access speed, a first clock generator for generating a reproducing clock corresponding to the transmission rate of a digital information signal, an oscillator for oscillating at a fixed frequency, a second clock generator for generating a master clock which is a reference of operations of a first controller for controlling the linear velocity, a digital signal processor, and a second controller for controlling the storage from the clock generated by the oscillator, a third clock generator for generating a master clock which is a reference of operations of the digital signal processor and the second controller without using the oscillator, and a switch for switching the master clock which is a reference of operations of the digital signal processor and the second controller to one of the clock by the second clock generator and the clock by the third clock generator are provided.
