Abstract
The method and apparatus for accessing data tracks calculate a reproduction speed of a target location based on a current rotation speed, adjust the speed of a data reading clock to the calculated rotation speed during movement of an optical pickup to the target location, and process signals reproduced at the target location with the adjusted data reading clock to restore the signals into data. The above procedures of changing the clock for data reading before an optical pickup is moved to a target location make it possible to reproduce recorded signals on an optical disk immediately after movement of optical pickup to the target location and to achieve quick access and stabilization in a track jump operation.
