Abstract

An apparatus and associated method for making a base for a data storage device. The base has a plurality of raised pads defining coplanar supporting surfaces. The surfaces are adapted for supportingly engaging intermittent portions of a component supported by the base so that the base clearingly disengages other portions of the component between the pads.

Claims

1. A base for a data storage device comprising a plurality of raised pads defining coplanar supporting surfaces, the surfaces adapted for supportingly engaging intermittent portions of a component supported by the base so that the base clearingly disengages other portions of the component between the pads.

2. The base of claim 1 wherein the component is a motor and the base defines a counterbore comprising the pads that supportingly engage an outer annulus of a stator portion of the motor.

3. The base of claim 2 wherein a first longitudinal surface defining a major diameter of the counterbore is sized for a close mating engagement with an outer diameter of the stator.

4. The base of claim 3 comprising an undercut in a lateral surface defining the counterbore at an intersection with the first longitudinal surface.

5. The base of claim 1 comprising three pads.

6. The base of claim 2 wherein the stator is stepped defining a first diameter and a second diameter larger than the first diameter, and wherein a second longitudinal surface defining a minor diameter of the counterbore is sized for a close mating engagement with the stator first diameter.

7. The base of claim 6 wherein the first longitudinal surface clearingly disengages the stator second diameter.

8. The base of claim 1 wherein the component is an actuator.

9. The base of claim 1 wherein the component is a head load/unload ramp.

10. A method for supporting a component in a data storage device, comprising:

stamping a base member;

coining a plurality of raised pads in the base member defining coplanar supporting surfaces;

placing the component on the plurality of raised pads; and

attaching the component to the base member.

11. The method of claim 10 wherein the attaching step is characterized by using a fastener device.

12. The method of claim 10 wherein the attaching step is characterized by using an adhering material.

13. The method of claim 10 wherein the attaching step is characterized by press fitting the component to the base member.

14. The method of claim 10 wherein the placing step is characterized by placing intermittent portions of the component against the pads so that the base member clearingly disengages the other portions of the component.

15. The method of claim 10 wherein the component is a motor and the placing step is characterized by placing an outer annulus of a motor stator on the pads.

16. The method of claim 15 wherein the stator is stepped defining a first diameter and a second diameter larger than the first diameter, and wherein the placing step is characterized by placing the stator in a counterbore defined by the base with the stator first diameter disposed in a counterbore minor diameter and the stator second diameter disposed in a counterbore major diameter.

17. The method of claim 10 wherein the component is characterized by one or more selected components of a set consisting of a motor, an actuator, and a load/unload ramp.

18. A data storage device comprising:

a data storage medium in a data storing and retrieving relationship with a data transfer device; and

means for supporting a component in relation to the data storage medium.

19. The data storage device of claim 18 wherein the means for supporting is characterized by a base member with parallelism features for locating a motor which, in turn, supports the data storage medium.

20. The data storage device of claim 18 wherein the means for supporting is characterized by a base member with parallelism features for locating a component which, in turn, supports the data transfer device.
