METHOD AND APPARATUS FOR RECORDING ADDRESS INFORMATION ON DISC MEDIUM

摘要

In step S1, an address generation block generates and pre-encodes a synchronization signal, address data, and address information composed of an error correction code of the address data which are to be recorded on an optical disc and outputs them to a modulation block. Simultaneously with thi s, a carrier signal generation block generates a carrier signal for carrying th e address information and outputs it to the modulation block. In step 2, the modulation block MSK-modulates the carrier signal input from the carrier signal generation block with the pre-encoded address information input from the address generation block and the obtained MSK-modulated signal is output to a wobble formation block. In step S3, the wobble formation block forms on the optical disc a spiral groove wobbled in accordance with the MSK-modulate d signal input from the modulation block. On this optical disc, an arbitrary address can be accessed rapidly.
