ABSTRACT:
An optical information recording medium includes a plurality of rows of tracking tracks arranged at intervals, a plurality of recording portions provided between the tracking tracks and on which information is recorded by application of a light beam thereto, and an optically detectable mark provided at at least one location on at least one of the recording portions. The recording surface of the recording medium is divided into a recording area and a non-recording area in a direction perpendicular to direction of the plurality of rows of the tracking tracks. The optically detectable mark represents a boundary of the recording area and the non-recording area.
