METHOD FOR RECORDING INFORMATION ON OPTICAL RECORDING MEDIUM, INFORMATION RECORDER, AND OPTICAL RECORDING MEDIUM

摘要

A method for recording information on an optical recording medium by forming, on the optical recording medium, recording marks selected from a group of plural kinds of recording marks having different lengths corresponding to n times n is a natural number the clock period T, wherein the recording marks are made by a laser beam composed of pulses the number of which is nT/Tr+Tf or less where Tr is the transition time necessary for the rise of the laser beam and Tf is the transition time necessary for the fall of the laser beam. Even if T is very short, the level of the laser beam can be made to reach the maximum value Pw or the minimum value Pb reliably, thereby making a recording mark having good shape.
