Abstract

A disc drive having a pivot cartridge and an actuator assembly. The actuator assembly consists of an actuator body which has a bore therein to receive the pivot cartridge. The actuator body further consists of an opening which serves as a ledge to engage a biased retaining ring. The biased retaining ring couples onto the pivot cartridge and forces the pivot cartridge to contact against one side of the bore of the actuator body.

Claims (19)

1. An actuator assembly comprising:

an actuator body having a bore, the bore defining an internal surface;

a pivot cartridge in the bore of the actuator body; and

a retaining ring for biasing the pivot cartridge toward one portion of the internal surface and away from another portion of the internal surface.

2. An actuator assembly as claimed in claim 1 , wherein the actuator body comprises a ledge spaced from the bore for engaging the retaining ring.

3. An actuator assembly as claimed in claim 2 , wherein the retaining ring comprises a hook which engages the ledge.

4. The actuator assembly of claim 1 , in which the retaining ring is split so as to define two ends, and further comprises a hook for engaging the actuator body, the hook being spaced from each end.

5. A disc drive comprising:

an actuator body having a bore defining an internal surface;

a pivot cartridge; and

means for biasing the pivot cartridge toward one portion of the internal surface.

6. The disc drive of claim 5 , in which the biasing means comprises a ledge formed in the actuator body spaced from the bore.

7. An actuator assembly comprising:

an actuator body comprising a vertically extending bore defining internal surface;

a pivot cartridge mounted in the bore, the pivot cartridge contacting one portion of the internal surface and being spaced from another portion of the internal surface horizontally spaced from the one portion of the internal surface; and

a retaining ring for securing the pivot cartridge within the bore.

8. An actuator assembly as claimed in claim 7 , wherein the actuator body comprises a ledge spaced from the bore for engaging the retaining ring.

9. An actuator assembly as claimed in claim 7 , wherein the retaining ring comprises a hook at one end for engaging the actuator body.

10. The actuator assembly of claim 7 , in which the ring is outside the bore.
