ABSTRACT:
An identification (ID) data transmission method for use in a disc player for performing servo control operations. An ID decoder reads and decodes the ID data from a signal recorded on an optical disc, and outputs the decoded ID data at a constant transmission rate to a microprocessor for controlling servo operations. The microprocessor compares the ID data transmission rate with an ID data processing rate of the microprocessor in the servo control, and controls the ID data transmission rate of the ID decoder based on the result of the comparison.. The disc player can efficiently perform timing and control of programs in the microprocessor.
