Abstract

PURPOSE:To decrease crosstalk from an adjoining track and to realize a reliable data reproducing action by controlling the positioning of a magnetic head using servo information on a servo surface. CONSTITUTION:At a hard disk device, seeking is executed on a data surface 23a of a disk 23 to rotate and drive a data head 21, and data reading/writing to a prescribed target track is executed. The head 21 is positioned and controlled to the center of the target track by a servo circuit 24. The circuit 24 sends a positioning control signal to correct the position error of the head 21 to a driving circuit 25 based on the servo information from a head 22, a carriage 20 is driven by the output, and the head 21 is positioned to the center of the target track. For the data surface 23a, its track interval is comparatively wide at an inner periphery side, and from the inner periphery side to an outer periphery side, the interval becomes narrower gradually.
