    • 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.
    • 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。

    • Processing to confirm management information during starting processing of a disk device is completely executed in a short period of time without scanning a data area to thereby minimize the period of time for the starting processing. The management information confirming processing can be executed after the disk device notifies the condition to the host or the user. Therefore, the response characteristic of the disk device is improved. Authentication information to certify that management information recorded on a disk is valid and invalidating information to invalidate the authentication information are provided. When the invalidating information to invalidate the authentication information is present, it is possible to determine that the management information is invalid or is possibly invalid. When the invalidating information to invalidate the authentication information is absent, it is possible to determine that the management information is valid according to the authentication information.
    • 在磁盘装置的开始处理期间确认管理信息的处理在短时间内完全执行,而不扫描数据区域,从而最小化起始处理的时间段。 管理信息确认处理可以在盘装置向主机或用户通知条件之后执行。 因此,提高了盘装置的响应特性。 提供认证信息,以证明记录在磁盘上的管理信息是有效的,并使信息无效使验证信息无效。 当存在使无效化认证信息的无效信息时,可以确定管理信息无效或可能无效。 当不存在无效认证信息的无效信息时,可以根据认证信息确定管理信息有效。
