When recording to the optical disk, information is recorded using a recording pulse where, due to the focused laser beam, the temperature in the recording layer cools more rapidly at a second information recording layer closer to the side where light is incident than at a first information recording layer farther away from the side where light is incident.

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 information recording apparatus, an optical information recording method, and an optical information recording medium that enable information signals to be recorded precisely by determining recording conditions such as recording power, edge positions of recording pulses, and the like suitably before recording information signals. An edge test signal generation circuit supplies a test signal for optimizing edge positions of recording pulses. In order to suppress the variation in intervals between edges due to mark distortion caused by overwriting, test recording is carried out using this test signal in a plurality of sectors on the optical information recording medium with a test recording start point being shifted at random in each sector by a recording start point shifting circuit. A system control circuit calculates an average of intervals between edges in test signals reproduced from the plurality of sectors and determines the difference between the average and an original interval between edges in the test signal, thus determining a compensation volume for edge positions.
