OPTICAL INFORMATION RECORDING MEDIUM, METHOD AND DEVICE FOR GENERATING OPTICAL INFORMATION RECORDING MEDIUM, AND METHOD AND DEVICE FOR DISCRIMINATING OPTICAL INFORMATION RECORDING MEDIUM

摘要

PROBLEM TO BE SOLVED: To record discrimination information enabling discrimination between a normal recording medium and a duplicated recording medium in a recording medium without decreasing record capacity of a recording medium.;SOLUTION: An optical information recording medium generating device generates an original disk 10 for forming an optical information recording medium in which main information is recorded by optical feature along a track. An optical deflector 14 in the optical information recording medium generating device deflects light passing through based on a track position control signal, and controls a position of a track formed on the original disk 10. Discriminating information for discriminating a normal optical information recording medium and a duplicated optical information recording medium is recorded in plural tracks by varying deviation in a tolerable range of a position of a track in the direction of crossing a track.;COPYRIGHT: (C)2001,JPO
