    摘要: Aspects of the invention include a method and apparatus to optimize the location of data on a disc drive storage system by optimizing the physical location of the file to allow the read ahead memory cache to operate more efficiently. In one aspect, the disc drive uses a reserved area on the media to hold files during the optimization process. In another aspect, the drive includes an optimization table that stores optimized file access data to further enhance the drive performance.

    摘要: A hang-up detector and an interrupt generator are provided in a disk controller incorporated in a disk storage system. By monitoring a command execution period, the detector detects whether the disk storage system reaches a hang-up state during the execution of a command in the system. The interrupt generator generates an interrupt to a CPU when the detector has detected the hang-up state. Upon receiving the interrupt, the CPU executes control for re-executing the command.

    摘要: A magnetic disk device having a head IC on a magnetic head supporting mechanism. In order to secure the reliability by controlling the IC temperature below a predetermined level, the difference in the IC cooling ability varying with the radial position on the disk is quantified, so that power (signal) sufficient to maintain a constant temperature according to the IC temperature is supplied to the IC. Since the cooling ability at a given radial position of the IC is not exceeded by the power consumption, the IC temperature can be maintained below a predetermined level.

    摘要: In recording, reproducing, and recording/reproducing apparatuses and methods thereof, while endlessly-recording first data, desired second data can be easily stored. The present invention comprises recording means for endlessly-recording the first data in a recording medium, input means for inputting a start and end point of the second data out of the first data, and control means, when the start point and end point are designated, for controlling the recording means so as to endlessly-record the first data while avoiding a recording region for the second data. Thereby, the second data can be stored without replacing the recording medium even if the second data is endlessly-recorded. In addition, when the start point and end point of the desired second data out of the first data are designated, the start point and end point are recorded, and then the first data is endlessly-recorded based on the recorded start point and end point while avoiding the recording region for the second data. Thereby, the second data can be stored without replacing the recording medium.

    摘要: A tape drive arrangement is configured to automatically adapt to drive different size tape cassettes and includes a sensor that senses the size of a tape cassette inserted into the tape drive. A controller is automatically responsive to the signals provided by the sensor to move drive spindles to respective different positions to drive different size tape cassettes.

    摘要: a method for determining and varying the capacity, track per inch and bit per inch values of a hard disk drive. The method includes determining an optimal track per inch value for each head of the drive. The method then determines whether each head does not exceed a threshold BER value. If one or more heads do not exceed the threshold BER value then the BPI (data rates) of the non-performing heads are decreased until an acceptable BER is achieved. The BPI of performing heads may be increased to insure that the capacity of the disk drive still meets a target value. Likewise, if all of the heads are above the threshold value, the BPI of one or more of the performing heads may be decreased to improve the BER of the heads. The reduction in BPI is limited so that the drive always meets the target capacity value. The BPI and TPI values are stored in memory for use during the operation of the drive.
