ABSTRACT:
An optical information recording apparatus, in which marks having a desired shape are recorded at desired positions, independently of the patterns of recording pulses, while canceling influences of the heat conduction from the mark, which has been directly previously recorded, by controlling the energy at the front end portion of laser light pulses, depending on the interval from the directly preceding pulse, when recording medium is irradiated with the laser light pulses corresponding to recording pulses so as to record information.
