Abstract: PROBLEM TO BE SOLVED: To remove contamination without the occurrence of fresh contamination by contact of a head and a disk. SOLUTION: Track following is performed in the outer peripheral part of the disk outside an effective recording region for a specified period after the head 3 is loaded onto the disk 1 from a ramp loading mechanism 17. The movement to the inner side of the disk and the movement to the outer side thereof are repeated in the outer peripheral part after the track following in the outer peripheral part of the disk. The velocity Vout of the outer side moving is set larger than the velocity Vin of the inner side moving, more preferably at about several times.
