Abstract

PURPOSE:To make the surface of a disk into a coarse plane at an arbitrary position on the disk, by moving a grinding tape with narrow width in the radius direction of the disk, and performing grinding by changing the rotating speed of the disk. CONSTITUTION:A tape with narrow width is used as the grinding tape 3, and a roller 4 pressurized contact with a magnetic disk 1 is linked to a rod 7 on an eccentric cam 6. The making of the surface into the coarse plane is performed by detecting the angle of rotation of the eccentric cam 6 and controlling the rotating speed of a spindle 2 variably. As a result, it is possible to perform the grinding by moving the tape 3 in the radius direction and changing the rotating speed of the disk. Therefore, it is possible to process surface coarseness being set at a reverse state to the floating quantity of a head so as to be decreased advancing from an outer peripheral part to an inner peripheral part, or to process so as to obtain uniform coarseness extending over from the inner peripheral part to the outer peripheral part.
