摘要： A storage device with a disk-shaped recording medium having servo areas in which servo sectors are recorded and data areas in which data sectors are recorded; a read/write head to read and write the data sectors, and to read the servo sectors on the disk-shaped recording medium; a head actuator to control the position of the read/write head; a storage controller to control data sector read and write operations by the read/write head; a servo controller to determine a position of the read/write head from the servo sector output read by the read/write head; a servo assist unit, separate from the storage controller, to calculate servo data for controlling the head actuator based on position information extracted by the servo controller and read/write head; and an interrupt generator to generate interrupt requests to the storage controller as determined by results of calculations by the servo assist unit.
