摘要：An optical information processor records predetermined information along atrack on a recording medium through the irradiation of a light beam intensity-modulatedin accordance with the predetermined information. A tracking signal obtained when thelight beam traces the track, is compared with first and second preset values which definea predetermined range. When the tracking signal departs from the predetermined range,the intensity modulation of the light beam or the recording operation is stopped,thereby preventing data destruction which otherwise occurs due to the digression of thelight beam from the track.
