摘要： In the read-write apparatus of the present invention, concentrated sliding of the read-write head in a specific area on the recording media is reduced. The recording media is rotationally set and the read-write head contacts the recording media to read and write information on the recording media. While the read-write head is accessing (read/write) the information on the recording media, a slide count calculation section calculates a slide count of the read-write head by monitoring the servo information of the recording media. The memory section stores the slide count calculated by the slide count calculation section by unit of access area. The relocation section suitably relocates the information recorded on the recording media in accordance with the slide count by unit of the access area.

摘要： A magnetic disk storage device has a magnetic disk with a storing/reproduction region formed thereon and a head slider facing the disk surface with a plurality of parallel projections to generate an air bearing. Magnetic heads each having a head gap are provided in the projections and have an interval between head gaps of at least 1/N of the width of the whole storing/reproduction region of the disk where N is the number of heads. The device makes it feasible to increase the number of heads per disk and to shorten the seek distance without increasing the weight of the head actuator.

摘要： A partial response (PR) waveform generator generates a digital value sequence of an expected PR waveform based on the output of a soft-decision Viterbi detector included in, for example, a first-stage decoder unit incorporated in an iterative decoder. The generator also generates flag information indicative of whether reliability of the digital value sequence is low or high, in parallel with the generation of the digital value sequence. An error detector detects error values in a PR equalized sample value sequence, needed for feedback control of a control target, using the digital value sequence of the expected PR waveform as a digital value sequence of a reference waveform. An error output controller controls the output of the error values detected by the error detector in accordance with the state of the flag information generated by the generator.

摘要： According to one embodiment, a disk drive is disclosed to which a plurality of disk rotational speed modes can be set. The disk drive is configured such that input of servo data from servo sectors is thinned out by thinning out an output of an interrupt request to a CPU in a high-speed rotation mode. At the time, a disk controller obtains servo data reproduced from all the servo sectors at timing of servo gates and stores it to a register.
