发明名称 Method for compensating for position error in an optical disc apparatus
摘要 A method for compensating for a position error in an optical disc drive (ODD) is provided. The method compensates for a position error generated by a step error associated with a motor which moves an optical pickup unit across a surface of an optical disc. Error data associated with each step of the motor is stored in a memory unit of the ODD, and compensation for the related position error is accomplished by compensating for a track-direction movement of an actuator. The method is particularly useful when conducting a label-printing operation, in that it allows the label printing operation to be performed without generating position errors, gaps, or overwrites on a label surface of the disc, thus enhancing the quality of a label-printing operation and the resulting label.
