Flying head slider capable of avoiding collision when loaded
View Patent ↗A flying head slider includes a slider body. The upstream or leading end of a bottom surface on the slider body is defined along a first datum line extending in the lateral direction of the slider body. The first datum line may be set perpendicular to the longitudinal centerline of the slider body. The upstream or leading end of the front air bearing surface is defined along a second datum line intersecting the first datum line at a predetermined inclined angle. As the incidence angle of an airflow colliding against a step defined at the leading end of the front air bearing surface gets decreased, the pitch angle of the slider body also gets decreased in the flying head slider during flight.
1. A flying head slider comprising:
a slider body;
a generally flat bottom surface defined on the slider body;
a front rail standing on the flat bottom surface at an upstream position so as to extend in a lateral direction of the slider body;
a front air bearing surface defined on a top surface of the front rail and extending in the lateral direction across a longitudinal centerline of the slider body;
a rear rail standing on the flat bottom surface at a downstream position;
a rear air bearing surface defined on the rear; and
a front facing surface defined on the front rail, the front facing surface standing on the flat bottom surface and defining an upstream end of the front rail, wherein
part of the front facing surface is retracted from a remaining part of the front facing surface in a downstream direction so as to define an air clogging dished space on the flat bottom surface.
