摘要: A modulation and demodulation system for an optical data recording reproducing apparatus is disclosed in which, disc having guide track capable of optically, the divided into a plurality sectors or reproduction reading effected by sector. The field different from that identification containing such as address sector way reproduced at high reliability speed while same time density field.
