Abstract
An address generator in the demodulator for an optical disk system generates addresses necessary for recording demodulated EFM in a predetermined area of a memory in the demodulator of an optical disk system, reading and recording the data for an error detection and correction of an EFM demodulation signal, and reading the data for converting digital signals for performing error correction into analog signals by using a scrambling counter and a decoder, thereby enabling quick generation of addresses while reducing chip space.
