Abstract: PROBLEM TO BE SOLVED: To provide a restoration time prediction method, a restoration time prediction device and a hard disk drive capable of effectively utilizing power restoration time required for restoration from a standby state and achieving the acceleration of the entire system provided with the hard disk drive. SOLUTION: When a host originates a request for releasing the standby state to this hard disk drive in a standby state, the power restoration time required for the hard disk drive to be restored from the standby state so as to become usable is predicted (S2). Then, the predicted power restoration time is reported to the host (S3). Since a host system recognizes the time required for power restoration, a schedule is made so as to execute a task to be ended within the time interval before the hard disk drive is started and the schedule of the task of the entire system inside the host system is optimized. Thus, the acceleration of the entire system provided with the hard disk drive is achieved.

Abstract: PROBLEM TO BE SOLVED: To provide a method for realizing a stream link in a voice/image disk medium and a device for the method. SOLUTION: A voice/image stream is set up in a disk drive device, and consecutive data are accessed with a read command and a write command. When a main stream which has been established exists, the stream link is established by sending to the disk drive device a request for the stream link provided with the number of the main stream. A new stream takes over the starting address and ending address of the main stream. When the pointer of a linked stream gets ahead of the pointer of the main stream, a pointer-overrun warning is set.
