Abstract
An apparatus allowing for a slider for use in a disk drive is disclosed. An embodiment of the present invention may include a leading side, a trailing side, at least two main rails, a slider surface with an air bearing surface, and at least one trench substantially parallel to the width of the slider. The trench in the air bearing surface results in a lower compression length of the slider and allows for particles to be channeled off of the disk surface.
Claims16
An air bearing slider comprising:
- a slider body defined by a leading edge, an inner and outer edge extending longitudinally along the slider body, and a rear edge, the slider body including an air bearing surface including a leading portion and a step region extending from the leading edge of the slider to the leading portion of the air bearing surface, the leading portion including a trench within the leading portion that extends from an inner edge of the leading portion to an outer edge of the leading portion.
A air bearing slider for use in a disk drive:
- a leading edge and a trailing edge;
- and
- an air bearing surface including at least two main rails and a leading portion, wherein the leading portion includes at least one set of trenches substantially parallel to a width of the slider.
A disk drive comprising:
- a disk coupled to spindle motor;
- an actuator;
- a slider including:
- a leading edge and a trailing edge;
- and an air bearing surface including a leading portion;
- at least two main rails;
- and
- at least one set of trenches within the leading portion and substantially parallel to a width of the slider.
