摘要： A system and method are provided that reduce the amount of data held commonly in both high-ranking and low-ranking cache memories, thereby having each of those cache memories hold data more efficiently. More particularly, a computer system is provided with an HDC card 21 connected to an expansion bus 20 and an HDD unit 22 connected to the HDC card 21. The HDC card 21 is provided with a disk cache (high-ranking cache memory) and the HDD unit 22 is provided with a disk cache 54 (low-ranking cache memory). The HDC card 21 and the HDD unit 22 exchange select information for selecting a swap mode of each cache memory when the system is started up, thereby selecting different swap modes according to the exchanged select information respectively.

摘要： An external controller performs a thorough analysis and prediction on true requests from an application to issue a look-ahead request to an HDD or other auxiliary storage. An HDC card is connected to an HDD device which stores data and has a cache memory. The HDC card, which controls the HDD device, includes an access request tracer for tracing a true access request made by an application program executed by a host directly from the application program, a speculation request determination section for determining a speculation request to be expected later based on the traced true access request, and an HDC for issuing the determined speculation request to the HDD device.

摘要： A method and an apparatus for predicting the recovery time required until the hard disk drive is restored to a usable state from a stand-by state. The recovery time is a time required until the hard disk drive is restored to a usable state from the stand-by state. Then, the predicted recovery time is reported to the host system. When the host system knows how much time is needed until the disk drive is recovered, it can schedule a task to be completed before the hard disk drive is restarted, thereby scheduling of all the tasks in the host system can be optimized.

摘要： A method and apparatus for providing passed pointer detection in audio/video streams on disk media. The present invention sets up an audio/video stream on a disk drive, uses read and write commands for accessing contiguous data and provides a pointer system that provides a warning when manipulating the pointers during fast forward and reverse functions that one pointer has passed the other. The position of a first pointer and a second pointer in at least one stream is monitored during a command execution. A determination is made when the positions of the first and second pointers cross to create a passed pointer state. An indicator is set to signal that a passed pointer state has occurred. The passed pointer indicator is then used to prevent anomalous behavior in processing of the at least one stream.

摘要： A disk drive device comprising a disk-shaped recording medium, having a recording surface on which a plurality of tracks having a predetermined width in a radial direction are defined, said recording surface including a first area wherein a plurality of recording tracks and a plurality of non-recording tracks are located so as to form an alternating pattern along the radial direction of the recording surface. The disk drive device may further comprise: a transducer to record information on the disk-shaped recording medium; a position error detector element to detect position error relative to a target track to be recorded on; an actuator to move the transducer to the target track according to the position error; and an end-of-seek detector, wherein when the transducer is moved to a target track inside the predetermined area the end-of-seek detector determines an end of seek based on whether the position error is less than a first threshold, and when the transducer is moved to a target track outside the predetermined area, the end-of-seek detector determines an end of seek based on whether the position error is less than a second threshold, wherein the second threshold is less than the first threshold.
