Abstract
An optimized low profile swage mount or press-in fitted base plate for attachment of a suspension assembly to an actuator arm in a hard disk drive. The base plate has a base plate thickness, TBP, overall height, HH, hub inner diameter, DID, hub outer diameter, DOD, hub inner surface depth, HIS, hub radial width, WH, which is one half the hub outer diameter minus the hub inner diameter (DOD-DID)/2, and a counter bore depth Hcb. The optimized parameters are such as to satisfy the following equation: W H T BP · W H ( H IS + H H - H cb ) / 2 ≥ 5
Claims12
An optimized low profile base plate for attachment of a suspension assembly to an actuator arm in a hard disk drive comprising:
- a flange having a flange thickness (TBP);
- and,
- a hub having, a hub height (HH), a hub radial width WH, a land height hub inner surface depth (HIS), and a lead in shoulder hub counter bore height (HCB);
- wherein:
- W H T BP · W H ( H IS + H H - H cb ) / 2 ≥ 5.
An optimized low profile base plate for attachment of a suspension assembly to an actuator arm in a hard disk drive comprising:
- a flange having a flange thickness (TBP);
- and,
- a hub having a hub height (HH), a wall thickness WH, a land height hub inner surface depth (HIS), and a lead in shoulder hub counter bore height (HCB);
- wherein:
- 8 ≥ W H T BP · W H ( H IS + H H - H cb ) / 2 ≥ 5.
A method of making an optimized low profile base plate for attachment of a suspension assembly to an actuator arm in a hard disk drive comprising steps of:
