摘要： Because a series of data is recorded continuously, the recording quality of data recorded in course of recording cannot be evaluated. Accordingly, the laser output cannot be controlled properly and there are a deterioration and dispersion of the recording quality. Further, when the recording lasts for a long time, the temperature in the vicinity of laser rises due to the heat from the inside of a disc drive and the recording quality is deteriorated.To solve this, a series of data to be recorded is split and recording is made intermittently in a split data unit. The recording quality is evaluated by reproducing the data recorded nearby before each split data is recorded using a duration and control is performed by reflecting the evaluation result in the laser output so that the recording quality can be maintained satisfactorily over a series of the whole data to be recorded. Further, control is performed so that good recording quality can be maintained even in the recording that lasts for a long time by stopping the function of each part that ought to be operated even at recording or reproduction inside the disc drive in the duration, thereby suppressing a temperature rise.
摘要翻译：由于一系列数据被连续记录，因此不能评估在记录过程中记录的数据的记录质量。因此，无法适当地控制激光输出，并且存在记录质量的劣化和分散。此外，当记录持续很长时间时，激光附近的温度由于来自盘驱动器内部的热而升高，并且记录质量劣化。为了解决这个问题，将要记录的一系列数据被分割并且在分割数据单元中间歇地进行记录。通过使用持续时间再现记录在每个分割数据之前附近记录的数据来评估记录质量，并且通过将评估结果反映在激光输出中来执行控制，使得可以在一系列整个数据中保持良好的记录质量，被记录。此外，进行控制，使得甚至即使在持续时间长的记录中也能保持良好的记录质量，即使在盘驱动器内的记录或再现期间，也可以通过停止应该被操作的每个部分的功能，从而抑制温度上升。
