ABSTRACT:
The present invention relates to an information recording/reproducing apparatus that radiates a laser beam to an information recording medium for recording and/or reproducing information, comprising: a laser beam generating means for generating a laser beam that records information to or reproduces information from the information recording medium; a timing control means for controlling information recording timing so that a recording area on a track of the information recording medium is followed by another recording area in a partially overlapping manner; and a laser beam intensity control means for controlling an intensity of the laser beam generated by the laser beam generating means so that a first area with information recorded, a second area with information erased, and a third area with information neither recorded nor erased are formed in the recording area in which information is at least recorded in an overlapping manner.
