ABSTRACT:
It is an object of the present invention to provide a method of recording information to an optical recording medium that is suited to achieving high data transfer rates.The optical recording medium according to the present invention comprises a method of recording information to an optical recording medium where information is recorded by forming on the optical recording medium a plurality of recording marks selected from a group consisting of several types of recording marks with different lengths each corresponding to n times (n is a natural number) the clock frequency T, wherein: taking Trto be the transition time required for a laser beam to rise and Tfto be the transition time required for the laser beam to fall, said recording marks are formed using a laser beam made up of a number of pulses given by nT/(Tr+Tf) or less. Thus, even in the case that one clock period (T) is extremely short, the power level of the laser beam can reliably reach the maximum value (Pw) and minimum value (Pb), so it is possible to form recording marks with a good shape.
