OPTICAL TYPE INFORMATION READ/WRITE APPARATUS

摘要

An optical-disk system is disclosed which comprises an optical-disk rotating in accordance with constant linear velocity technique, a signal input device for producing an information signal digitally encoded, and address generator for generating an address signal, an interleave circuit for commonly leaving both the information signal and the address signal, and a write controller for modulating a write beam incident to the optical-disk in response to the output signal from the interleave circuit and for forming at least one sector including both the commonly interleaved signals on the optical-disk.
