    • To provide a spindle motor control method adapted to an optical disk recording and reproducing apparatus capable of recording a signal onto a disk using a laser applied from an optical pick-up, a reference signal originated from a disk (1) and a reference signal necessary for signal recording are synchronized to each other when resuming signal recording once suspended. The synchronization is established without using a phase error component. Once synchronization is established, a phase error component is added to a servo signal of the spindle motor (2). A gain for a phase error component is begun gradually increasing after a phase error component is begun being added to a servo signal. An upper limit value of the gain of a phase error component to be added is determined depending on the location of a part on the disk (1) at which to resume the once suspended signal recording.
    • 为了提供一种适用于能够使用从光学拾取器施加的激光将信号记录到盘上的光盘记录和再现装置的主轴电动机控制方法,来自盘(1)的参考信号和必要的参考信号 当暂停信号记录时,信号记录被彼此同步。 在不使用相位误差分量的情况下建立同步。 一旦建立了同步,则将相位误差分量加到主轴马达(2)的伺服信号上。 在相位误差分量开始加到伺服信号之后,相位误差分量的增益开始逐渐增加。 要添加的相位误差分量的增益的上限值是根据恢复暂停信号记录的盘(1)上的部分的位置确定的。

    • A storage system capable of identifying all volumes to be audited is provided.Operation logs 3005 concerning the operations of volumes are associated with a time and stored in storage apparatuses 1400 and 1500, and a management computer 1100 collects information about these operation logs 3005, restores the status history of the operation logs 3005, sets, as an audit range, the operation logs 3005 including volumes with an audit period and audit target data stored therein, extracts the operation logs 3005 belonging to the audit range from the restored status history of the operation logs 3005, and transmits the extracted operation logs 3005 to a computer (requesting computer) 1000. As a result, all the audit target volumes can be identified.
    • 提供了一种能够识别要审核的所有卷的存储系统。 关于卷的操作的操作日志3005与时间相关联并存储在存储设备1400和1500中,并且管理计算机1100收集关于这些操作日志3005的信息,恢复操作日志3005的状态历史,设置为审计 范围内,包含审核期间的卷和审核对象数据的操作日志3005从恢复的操作日志3005的状态历史中提取属于审核范围的操作日志3005,并将提取的操作日志3005发送到计算机 (请求计算机)1000.因此,可以识别所有审核目标卷。
