INFORMATION RECORDING APPARATUS AND METHOD, COMPUTER PROGRAM, AND INFORMATION RECORDING MEDIUM

摘要

An information recording apparatus (300) comprising recording means (352) for recording information by applying a laser beam onto an information recording medium (100), obtaining means (354) for obtaining at least one of (i) a special OPC strategy to define the waveform of the laser beam applied at a first recording speed to calculate the optimum laser power of the laser beam of when information is recorded at a second recording speed different from the first one and (ii) a recording strategy to define the waveform of the laser beam used to record information at the second recording speed, power calculating means (354) for calculating the optimum laser power at the first recording speed by using the special OPC strategy, and control means (354) for controlling the recording means to record information at the second recording speed by using the calculated optimum laser power and the recording strategy.
