Abstract: PURPOSE: To correct the mismatch of tracks when reading and writing elements, which are separated to a slider of a head.assembly, are included. CONSTITUTION: Offsets are fundamentally determined at first and second positions of an actuator.arm.assembly. Then, from these offsets, the constants and the multiplier are determined to set the offsets as a function of cylinder positions. Moreover, the method and the device are provided to make the movement distance minimum in order to prevent the mismatch while conducting a repositioning between the reading and writing elements. The reading element is intentionally offset from the writing element with an angle in which the movement distance across a disk is made minimum.
