ABSTRACT:
An optical information recording apparatus for at least recording information by irradiating an optical information recording medium having a plurality of information tracks with at least one light beam. The apparatus includes a recorder for recording information on the recording medium with an information recording light beam and a plurality of detecting elements for detecting reflected light from the recording medium. Also provided is a high-frequency component detector for detecting a high-frequency component of a signal corresponding to an output signal from at least one of the plurality of detecting elements. Also provided is a controller for stopping recording of information by the recorder when the high-frequency component detector detects the high-frequency component during recording of information by the recorder.
