摘要： When data is reproduced by an apparatus which is different from an apparatus used for recording the data, the fluctuation of edge positions of the reproducing data increases, making reproduction incompatible, and the present invention solves this problem. The present invention comprises reproducing learning means 13 and 24 for switching a frequency characteristic of the reproducing system, which detects the changes of the local optical constant, to a predetermined frequency characteristic, and recording learning means 20 for correcting the start edge or end edge position of the recording pulse for each combination of length of a mark block and length of the preceding or subsequent space, so that the edge position of the binarized reproducing data comes to a desired position, and since the frequency characteristic of the reproducing system is unified before learning the edge shift amount caused by the thermal interference between marks, the length of the recorded marks and spaces can always be constant, which improves the reproducing compatibility among reproducing apparatuses.

摘要： An optical disc apparatus reads the address information from an optical disc which has tracks and track spaces formed between tracks. The apparatus has an optical head which irradiates the disc with light and includes tracking detectors, divided into a first detector and a second detector in a track direction, detecting the light reflected from the disc and outputting detection signals, an adjusting circuit which adjusts amplitudes of the first and second detection signals and outputs the signals at a position where the address information is recorded, a differential amplifying circuit which outputs the differential signal which is the difference between the adjusted first and second detection signals, and an address detecting circuit which detects the address information based on the differential signal. As a result, the optical disc apparatus accurately detects whether information is being recorded on a correct track and improves the reliability during recording.
