ABSTRACT:
An optical recording apparatus for recording a pulse signal on a recording medium by using a laser light beam, wherein, as shown in FIG. 4 , for example, a pattern detecting circuit (31) is provided to detect a pulse pattern of a recording signal, and an amplitude of a succeeding signal pulse is decreased in accordance with a control signal from a memory (33) when a pulse interval is not more than a predetermined value to thereby decrease a radiation energy of a laser light pulse, whereby the influence of remaining heat of the recording medium due to a laser light pulse corresponding to a preceding laser light pulse is cancelled to make it possible to record a high-density pulse signal accurately.
