Abstract

A slider for use in a disc drive data storage system is disclosed. The slider includes an air bearing surface, a top surface and a first surface extending between the air bearing surface and the top surface. The first surface is oriented relative to at least one of a plane of the air bearing surface and a plane of the top surface such that the first surface forms an oblique angle with the plane to thereby provide increased surface area on the first surface.

Claims

1. A slider for use in a disc drive data storage system comprising:

an air bearing surface formed substantially in a plane;

a top surface oriented substantially parallel to the plane of the air bearing surface;

a substantially planar trailing edge surface extending from the air bearing surface to the top surface such that the trailing edge surface forms a first oblique angle with the plane of the air bearing surface; and

a substantially planar leading edge surface extending from the top surface to the air bearing surface such that the leading edge surface forms a second substantially oblique angle with the top surface.

2. The slider of claim 1, wherein the second substantially oblique angle is approximately equal to the first substantially oblique angle.

3. The slider of claim 2, and further comprising first and second side surfaces disposed between the air bearing surface and the top surface and between the trailing edge surface and the leading edge surface, wherein the first and second side surfaces are each oriented substantially perpendicular to the plane of the air bearing surface and to the top surface.

4. A slider for use in a disc drive data storage system comprising:

an air bearing surface;

a top surface spaced apart from and parallel to the air bearing surface;

a trailing edge surface extending from a first end of the air bearing surface to a first end of the top surface, wherein the trailing edge surface is oriented such that a minimum distance across the trailing edge surface from the air bearing surface to the top surface is greater than a minimum distance between the air bearing surface and the top surface in a region of the slider proximate the trailing edge surface;

a leading edge surface positioned at a second end of the air bearing surface and at a second end of the top surface;

a magnetic transducer located at the trailing edge surface of the slider; and

bond pads coupled to the magnetic transducer and located at the trailing edge surface of the slider for electrically coupling the transducer to external circuitry;

wherein the trailing edge surface is oriented at a first oblique angle relative to one of a plane of the top surface and a plane of the air bearing surface to thereby provide an increased surface area of the trailing edge surface, and the leading edge surface is parallel to the trailing edge surface.

5. The slider of claim 4 and further comprising first and second side surfaces disposed between the air bearing surface and the top surface and between the trailing edge surface and the leading edge surface, wherein the first and second side surfaces are each oriented substantially perpendicular to planes of the air bearing surface and the top surface.

6. A disc drive data storage system comprising:

a magnetic disc having a first disc surface;

a slider comprising;

an air bearing surface;

a top surface;

a substantially planar trailing edge surface positioned at a first end of the air bearing surface and at a first end of the top surface and extending therebetween;

a substantially planar leading edge surface positioned at a second end of the air bearing surface and at a second end of the top surface and extending therebetween wherein the leading edge surface is oriented at a second oblique angle relative to at least one of the plane of the top surface and the plane of the air bearing surface;

a magnetic transducer; and

bond pads coupled to the magnetic transducer and located at the trailing edge surface of the slider for electrically coupling the transducer to external circuitry, wherein the trailing edge surface is oriented at a first oblique angle relative to at least one of a plane of the top surface and a plane of the air bearing surface to thereby provide an increased surface area of the trailing edge surface; and

a slider carrying arm for supporting the slider over the first disc surface of the magnetic disc.

7. The slider of claim 6, wherein the leading edge surface is further oriented parallel to the trailing edge surface.

8. The slider of claim 7, and further comprising first and second side surfaces disposed between the air bearing surface and the top surface and between the trailing edge surface and the leading edge surface, wherein the first and second side surfaces are each oriented substantially perpendicular to the air bearing surface and to the top surface.
