A disk storage medium and a disk drive which reduce friction during landing of the head/slider is described. The minimum fly height area of the head/slider is positioned over a texture free portion of the landing zone on the disk surface landing. In a preferred embodiment, the landing zone of a magnetic disk is a laser texture zone comprising a great number of bumps and is positioned during landing adjacent an area other than the minimum fly height area of the head/slider. The area facing the minimum fly height area of a head/slider has no bumps, i.e. is a bump free zone.

In the slider 1 on which a transducer 5 is mounted and which moves above a recording surface 4, in order to generate different vibration modes according to various situations such as vertical lift-off and landing, and breaking away from stiction, etc. A plurality of piezo-electric elements 8A, 8B, 8C, and 8D are disposed on the slider 1 and means for supplying a different AC voltage to each of the piezo-electric elements 8A, 8B, 8C, and 8D is provided.
