摘要： A method and apparatus for recording data on a magnetooptical recording medium finds an optimum laser beam intensities for recording. The method and apparatus do not cause a low level P.sub.L setting to become excessively low and poor overwriting of data during overwrite recording. Recording can be accomplished changing low level and high level laser beam intensities, while holding the ratio of the low level and high level laser beam intensities constant. Data can be reproduced and evaluated. When the optimum laser beam intensities have not been determined, the intensity ratio of the low level and high level intensities can be altered. After data has been is reproduced and evaluated, the process can be repeated, until the optimum laser beam intensities are obtained. Further, recording can be based on temperature of the recording medium and surroundings to obtain optimum laser beam intensities.

摘要： A method of performing stabilized overwriteable optical recording, wherein overwriting is performed sufficiently even when erasure becomes poor when the low level laser beam intensity P.sub.L is set too low. The low level of recording laser beam intensity is set by playing back a test recording region by illuminating magnetization reversal areas after magnetization reversal areas have been formed in test regions of an overwriteable optical recording medium. Further, an erasure factor is found from the playback signal. In a second embodiment of a method of setting the recording laser beam intensity in order to perform recording on an overwriteable optical recording medium, before a test recording is performed, magnetization reversal areas are formed in a test recording region. These magnetization reversal areas are not erased, and a test recording is performed in this region by overwriting.

摘要： A stabilized overwriteable optical recording method, wherein overwriting is performed sufficiently because erasure does not become poor with a low level laser beam intensity P.sub.L set too low. The method includes setting the recording laser beam intensity in order to perform recording on an overwriteable optical recording medium, finding the lower limit value of laser beam intensity at which a high temperature process occurs, and, based on this lower limit value of laser beam intensity, provisionally setting a high level laser beam intensity. After magnetization reversal marks have been formed in a test recording region by this lower limit value, the test recording region is played back. Then, after the test recording region has been illuminated with a laser beam, performing erasure of the magnetization reversal marks. Then the test recording region is played back, and by making a comparison of the playback signals before and after erasure was performed, the optimum low level laser beam intensity is set.

摘要： A data erasure device for an optical recording medium which controls the effects of a temperature rise of an optical recording medium during an erasure operation. The data erasure device irradiates a light beam on a recording medium, and erases data recorded on the medium by increasing the temperature of a portion of the recording medium irradiated by the light beam. The light beam is caused to blink between two states during the erasure operation to produce a uniform erasure mark.
