OPTICAL RECORDING MEDIUM, METHOD AND APPARATUS FOR RECORDING INFORMATION ONTO OPTICAL RECORDING MEDIUM

摘要

An information recording method for recording information by forming on an optical recording medium a plurality of recording marks selected from a group consisting of a plurality of types of recording marks having different lengths from one another. A first recording mark and a second recording mark contained in the group are formed by setting the number of pulses and the pulse interval of the laser beam substantially identical. Thus, even when the clock cycle T is reduced for realizing a high data transfer rate, it is possible to form a recording mark having a preferable shape. Moreover, control is easy and it is possible to reduce the cost of the drive to which the present invention is applied.
