    摘要: A hard disk drive and magnetic medium including a servo area, a data area divided into a plurality of sector blocks and at least one micro-servo area disposed between two sector blocks. There may be a micro-servo area immediately preceding each of the plurality of sector blocks. The micro-servo areas include an address mark and a track parity check code that allow the detection of an external shock that causes the recording (write) head to skip to an adjacent track in the hard disk medium. The micro-servo area is smaller than the servo areas, and various numbers of different track parity check codes can be used for different resolution of shock detection. An acceleration sensor may also be provided to detect larger external shocks. By detecting various external shocks with improved accuracy, and aborting the recording operation of data if an external shock is detected, the corruption of data in adjacent tracks is substantially reduced to improve disk drive performance.

    摘要: An information storage medium in which speed information has been recorded, and a method of recording and/or reproducing data on the information storage medium. The information storage medium includes a reproduction-only area in which recording speed information and/or reproducing speed information which indicate whether a drive can record and/or reproduce data on the information storage medium are recorded. The method of recording and/or reproducing data in an information storage medium, the method includes: recording, as reproduction-only data in a reproduction-only area, recording speed information and/or reproducing speed information, which is used to indicate speed capabilities to a drive; and recording or reproducing data on the information storage medium when a recording speed or a reproducing speed capability of the drive matches the recording speed information or the reproducing speed information.

    摘要: In a medium having a restriction on its function which has an extremely low overwrite cyclability as compared with a common one, information is arranged so as to allow restricted write and read operations in a commonly current write and read drive, i.e., the medium is subjected to specific formatting. It is possible to perform write and read operations with security. The specific format can be performed with parameters taking the special-purpose using conditions (i.e., overwrite cyclability) into consideration. Consequently, it becomes possible to provide a low-priced information recording medium.
