  • Patterned-media magnetic recording disk drive with data island misplacement information in the servo sectors
    Patent number: 8427772
    Abstract: A disk drive with patterned-media disks has information recorded in the servo sectors that identifies misplacement of the data islands in the data regions between the servo sectors. This misplacement information is read from the servo sectors prior to writing to correct either or both the radial position of the write head and the timing of the write pulses to the data islands. The misplacement information may include radial deviation of the data tracks, circumferential or along-the-track misplacement of the data islands, or the location of defective data islands.
