INFORMATION RECORDING MEDIUM AND RECORDING METHOD

摘要

PROBLEM TO BE SOLVED: To record a mark on a correct position by obtaining the optimum moving amounts of a first pulse and a last pulse corresponding to the data pattern prior to the data recording. SOLUTION: The reproduction of a signal on a track on which a specific pattern is recorded is carried out, and the specific edges interval in the signal binarized by a specified slice level in a binarization circuit 115 and converted to the signal string of 0, 1 is measured by a measuring circuit 120 for the positional deviation to pulse. The setting of the moving amounts of the first and last pulses of a pulse moving circuit 110 is updated so that the deviation amount between the measured edge interval and a normal value is reduced.
