Claims
- 1. A method of contouring a surface portion of a head for a disc drive that includes a disc rotatably mounted on a base, the method comprising:
positioning the head over a park zone of the disc; and rotating the disc for a selected time to burnish the head against the park zone of the disc while maintaining the head positioned substantially over the park zone.
- 2. The method of claim 1, wherein the park zone comprises a textured surface.
- 3. The method of claim 2, wherein the textured surface includes bumps that interact with the surface portion of the head.
- 4. The method of claim 1, wherein the rotating step includes rotating the disc at a fixed rotational speed for the selected time.
- 5. The method of claim 4, wherein the fixed rotational speed is less than an operating rotational speed of the disc.
- 6. The method of claim 5, wherein the fixed rotational speed is less than a take off speed of the head.
- 7. The method of claim 4, wherein the rotating step comprises rotating the disc for a period of time of from about five minutes to about thirty minutes.
- 8. The method of claim 1, wherein the rotating step includes plural sequences of starting and stopping the disc.
- 9. The method of claim 8, wherein the rotating step includes from about 100 to about 500 starting and stopping sequences.
- 10. A disc drive including a disc rotatably mounted on a spindle motor mounted on a base and an actuator assembly mounted adjacent the disc, the actuator assembly having an actuator arm including a distal end supporting a head over a surface of the disc, the head comprising:
a head surface portion facing the disc surface, wherein the head surface portion has been contoured by positioning the head over a park zone on the disc and maintaining the head positioned substantially over the park zone of the disc while rotating the disc for a selected time so as to burnish the head surface portion.
- 11. The disc drive of claim 10, wherein the head surface portion has a roughness of less than about 0.5 nanometers.
- 12. The disc, drive of claim 10, wherein the park zone comprises a textured surface defining a plurality of bumps that interact with the surface of the head as the head is burnished.
- 13. The disc drive of claim 12, wherein the disc is rotated at a fixed rotational speed for the selected time as the head is burnished.
- 14. The disc drive of claim 13, wherein the fixed rotational speed is less than an operating rotational speed of the disc drive.
- 15. The disc drive of claim 14, wherein the fixed rotational speed is less than a take off speed of the head.
- 16. The disc drive of claim 13, wherein the disc is rotated for a period of time of from about five minutes to about thirty minutes.
- 17. The disc drive of claim 12, wherein the disc undergoes a plurality of starting and stopping sequences as the head is burnished.
- 18. The disc drive of claim 17, wherein the plurality of starting and stopping sequences is between about 100 and about 500 sequences.
- 19. A method of contouring a surface portion of a head for a disc drive that includes a disc rotatably mounted on a base, the method comprising:
positioning the head over a park zone of the disc; and contouring the head surface portion to reduce contact between the head and the disc during operation of the disc drive.
- 20. The disc drive of claim 19, wherein the contouring step comprises rotating the disc at a fixed rotational speed for a selected time.
- 21. The disc drive of claim 19, wherein the contouring step comprises plural sequences of starting and stopping rotation of the disc.
