Abstract

PURPOSE:To improve the using efficiency of a magnetic disk by fitting a head for a servo, whose moving radius is small, to a swinging arm common to a head for data and reading a servo pattern in the moving range. CONSTITUTION:A head 22 for a servo is fitted on the swinging arm of the center position of a rotation center 24 of a swinging arm 23 and a head 21 for data. An area corresponding to the moving range of the head 22 for the servo in the moving range of the head 21 for the data in a magnetic disc 19 is made into a servo area 26, and another areas are set in a data area 27. Corresponding to that the head 21 for the data is moved in the using range of the magnetic disc 19, the head 22 for the servo moves the servo area, and when the head 22 for the servo is in the vicinity of a track for a servo, the head reads, successively and with the rotation of the magnetic disk, level information from the servo patterns abusent to one another. Thus, the using efficiency of the magnetic disk can be improved.
