Abstract

PURPOSE:To increase a floating amt. of a magnetic head and to prevent a collision against a protrusion part on the surface of a CSS area by driving a disk at higher speed in its rotation at the time of commencing a read/write operation than that at the time of its normal rotation. CONSTITUTION:A drive control means (motor drive control circuit) 24 is provided to control a rotating mechanism 21 in its drive, so as to drive a magnetic recording medium 23 at higher rotating speed than that at the time of read/write of data; when the magnetic head 26 is positioned in the contact-start-stop (CSS) area 12 at the time of commencing the read/write of the data. By this method, even when the surface smoothness of the CCS are 12 of the magnetic recording medium 23 is deteriorated to prevent a sucking phenomenon with the magnetic head 26, the floating amt. of the magnetic head at the time of its floating becomes larger, so that the situation of the magnetic head 26 to come into collision with the protrusion part of the surface can be prevented.
