Abstract
A disk drive system including a disk having a contact surface and a slider having a surface with a pattern of features is described. The disk's contact surface is textured with protrusions that roughen surface. The distance between the protrusions on the disk is less than the distance between the features on the slider surface.
Claims11
An apparatus, comprising:
- a disk;
- and
- a body in sliding contact with a contact surface of the disk during a portion of an operation of the disk, the body having a surface comprising a pattern of features having a first distance between the features, and
- wherein the disk comprises at least a first zone that includes the contact surface, the first zone having a roughness comprising a plurality of protrusions having a second distance between the protrusions, wherein the second distance between the protrusions is less than the first distance between the features.
1 more element
A method, comprising:
- providing, on a body, a surface comprising a pattern of features having a first distance between the features, the body capable of sliding contact with a contact surface of a disk;
- and
- providing, on the disk, a roughness for at least a first zone by texturing the first zone to generate a plurality of protrusions having a second distance between the protrusions, wherein the second distance between the protrusions is less than the first distance between the features.
