Magnetic head slider with side pads which each have a width W and a length L, wherein W>L
View Patent ↗A magnetic head slider, for sliding on a magnetic disk, which has a leading edge, a trailing edge, an air bearing surface having a front step bearing of submicron depth made from the leading edge, and a rail surface made from the front step bearing. A negative pressure recess which is deeper than the front step bearing, is formed as a recess from the rail surf ace, and a side step bearing with a depth identical to that of the front step bearing is made from the rail surface. Side padB are provided which each have a width W and length L, wherein W is greater than L.
1. A head slider comprising:
a leading edge;
a trailing edge;
a front step bearing formed from the leading edge;
a rail surface formed between the front step bearing and the trailing edge;
a first side pad and a second side pad formed between the rail surface and the trailing edge,
a first side step bearing formed between the rail surface and the first side pad; and
a second side step bearing formed between the rail surface and the second side pad;
wherein each of the side pads has a width W in a width direction of the slider and a length L in a length direction of the slider, and wherein W>L; and
wherein each of the first arid second aide step bearings is divided into two parts in a length direction of the slider.
