ABSTRACT:
An optical information recording method for recording one of signals "1" and "0" in each of bit positions alloted at regular intervals along a track of a recording medium. The method comprises the step of enhancing energy for recording a bit of "1" which is directly subsequent to a bit of "0" in comparison to energy for recording a bit of "1" which is directly subsequent to a bit of "1".
