PLURAL DRIVE DEVICE DELAY COUNTERMEASURE AND RECORDING/REPRODUCTION DEVICE PERFORMING POWER SAVING CONTROL

摘要

By combining a plurality of cheap hard discs of intermediate capacity, it is possible to perform recording of a data capacity equivalent to a large-capacity hard disc. By performing power saving management, it is possible to minimize the power consumption of the hard discs. Simultaneously with this, in order to eliminate a delay when accessing a different hard disc, drive devices other than the access object are set to a power saving state. While access to one drive device is continuing, the remaining time of the access to the drive device is calculated, so that while the drive device is being accessed, the next drive device to be accessed is set to a standby state from the power saving state.
