Optical information storing device, data processing circuit and information storage medium

摘要

The present invention aims at providing an inexpensive optical information storing device that produces reduced cross talk. An optical information storing device has a cyclic data output circuit 14 _- 1 that outputs cyclic data in which values are repeated every 5 bytes, and an EXOR circuit 14 _- 2 that calculates the exclusive-OR (EXOR) of recording data input thereto via a buffer 14 _- 5 and the cyclic data and inputs the calculation result to an RLL modulation circuit 14 _- 3 as data to be recorded.
