  • Storage apparatus, storage apparatus control method, and computer product
    Patent number: 7436612
    Abstract: A calculating unit calculates an interval time from a detection of a servo sync mark until a detection of an adjacent servo sync mark, for all servo sync marks on a track of a disk-shaped recording medium. A measuring unit measures, based on the calculated interval time, a deviation amount between a link interval time that represents the interval time between a servo sync mark recorded first and a servo sync mark recorded last and an ideal interval time that represents the link interval time when it is assumed that all the servo sync marks on the track are written at equal intervals.

  • Head slap detecting device, storage device, head slap detecting method, and computer product
    Patent number: 7420762
    Abstract: A head-slap detecting device detects a head slap. The head slap causes a storage medium to be slapped by at least one storage-medium driving unit that performs at least one of reproduction and recording of data from and to the storage medium. The head-slap detecting device includes a detecting unit that detects the head slap by determining whether a first variable gain obtained from a variable gain amplifier that amplifies an output of data reproduced by the storage-medium driving unit exceeds a predetermined threshold.

  • Storage apparatus, storage apparatus control method, and computer product
    Publication number: 20070064337
    Abstract: A seek-information storing unit stores seek information including a correlation between a seek distance indicating a shift distance from a current track to a target track where a target frame for a data input/out is located and a seek time indicating a shifting time that takes for a head to shift from the current track to the target track, based on an actual measurement. A head-shift control unit controls a shift of the head based on an estimated time obtained by adding a rotational delay time that takes until the target frame arrives at the head position after the head arrives at the target track to the seek time acquired from the seek information.

  • Medium storage device and medium rotation synchronization processing method for medium storage device
    Publication number: 20060203371
    Abstract: A medium storage device writes or read data on a storage medium synchronizing the rotation of the storage medium with the DSW method for decreasing the gap length considering the rotation jitter. The medium storage device has a controller for generating synchronization timing signals during reading/writing from a clock, and a processing unit for calculating the correction value of the frequency from the measurement result of the servo synchronization mark space of the storage medium. The processing unit judges whether or not the detected interval of the servo synchronization marks is within a predetermined range which is not occurred a frequency compensation to influent an error rate when reading, and corrects the synchronization timing of the controller based on the interval of the servo synchronization marks when the detected interval is judged within the predetermined range.
