Abstract
A disc drive is disclosed that includes textured features on the disc surface and a slider. The slider texture can include one or more features oriented in a first direction, and the disc can include one or more features oriented in a second direction. The first and second directions are selected such that the second direction includes a component that is perpendicular to the first direction. The orientation of the features facilitates the provision of matrix of contact points between the slider and the disc surface.
Claims18
A disc drive comprising:
- a disc for storing data, the disc having first stiction reduction means;
- a slider for reading and writing data on the disc, the slider having second stiction reducing means for cooperating with the first stiction reduction means to reduce stiction between the disc and the slider, the second stiction reducing means including a plurality of slider texture regions.
A disc drive comprising:
- a rotating disc having a disc surface with a disc texture applied thereon including a disc feature extending in a first direction wherein the disc texture extends from the disc surface;
- read/write circuitry for reading data from and writing data to the rotating disc;
- a controller for providing control signals;
- an actuator assembly coupled to the controller, receiving the control signals and providing actuation based upon the control signals;
- and
- a slider coupled to the actuator assembly and having a head operably coupled to the read/write circuitry, the slider having an air bearing surface with:
- a first slider texture region applied thereon including a first slider feature extending in a second direction, the second direction having a component substantially perpendicular to the first direction, wherein the first slider texture region extends from the air bearing surface;
- and
- a second texture region including a second slider feature extending in a third direction, the third direction having a component aligned substantially perpendicular to the first direction, wherein the second texture region is spaced from the first texture region.
