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.
摘要翻译：一种用于在擦除操作期间控制光学记录介质的温度升高的影响的光学记录介质的数据擦除装置。数据擦除装置将光束照射在记录介质上，并且通过增加由光束照射的记录介质的一部分的温度来擦除记录在介质上的数据。在擦除操作期间使光束在两个状态之间闪烁以产生均匀的擦除标记。
