A disk player

Abstract From the Canadian patent

The present invention provides a disk player which is, capable of changing the playing linear velocity by a multiple stages to shorten the reading time. The disk player includes the conventional motor, and an optical pick-up. A first clock section generates master clock signals for changing the, frequency of the master clock signals by multiple stages as, well as an oscillating circuit for generating standard clock signals. First and second divider circuits divide the standard clock signals and generate first and second divided signals. A phase comparing circuit compares the phases of the first and second divided signals and generates phase-deviation signals which correspond to the phase …
