Optical information medium, optical information recording method and optical information recording apparatus

Abstract

Provided are an optical information medium, an optical information recording method and an optical information recording apparatus in which an accurate cross talk can be predicted with a simple structure in a recording mode such as CLV so that a disk having a cross talk reduced can be created. The optical information recording apparatus is caused to generate a modulating signal based on data and to then predict a bit string on a disk to be generated during recording of the modulating signal on an optical disk and to predict the position of the bit string in relation to a rotation angle in the optical disk, and further comprises a cross talk compensation value computing circuit (7) for computing information on adjacent tracks in response to information on the rotation angle thus obtained and the modulating signal, a timing correcting circuit 8 for obtaining a correction value based on an output of the cross talk compensation value computing circuit (7), and an optical modulator 10 for correcting the modulating signal based on the corrected value.
