Described herein is an actuator latch, for limiting rotational movement of a disk drive actuator. The latch preferably includes a coupling portion that has an elongate member received by a bore in a disk drive base. The coupling portion is configured to be rotatable about an axis defined by the elongate member. The latch also includes an engagement portion, integrally formed with the elongate member, that extends in a direction transverse to the axis and engages and limits rotation of a disk drive actuator.

1. A disk drive comprising: a disk drive base having a coupling portion, the coupling portion extending from the base and having a bore therein;a disk, rotatably coupled to the disk drive base, the disk having a recordable surface;an actuator rotatably coupled to the disk drive base, the actuator having an actuator arm that is rotatable to a position over the recordable surface when the disk drive is in an operation mode and is rotatable to a position substantially not over the recordable surface when the disk drive is in a non-operation mode; anda latch that is rotatably coupled, about an axis of rotation, to the coupling portion of the base, the latch having an engagement portion that engages the actuator to limit rotational movement of the actuator when the disk drive is in the non-operation mode and permits rotational movement of the actuator when the disk drive is in the operation mode, the latch having a base portion that forms a pin, and the pin being received by the bore of the base coupling portion to provide relative rotational movement between the latch and the base. 2. The disk drive of claim 1, wherein the latch further comprises a dome, aligned along the axis, on a top portion, the dome providing an area of contact between the latch and a top cover of the disk drive. 3. The disk drive of claim 1, wherein the pin is formed integrally with the latch. 4. The disk drive of claim 3, wherein the pin and the latch are molded as a single unit. 5. The disk drive of claim 1, wherein the pin and the latch form a unitary member. 6. The disk drive of claim 1, wherein the latch comprises a plurality of materials. 7. The disk drive of claim 6, wherein the engagement portion comprises a different material than the pin. 8. The disk drive of claim 1, wherein the engagement portion comprises a polymer. 9. The disk drive of claim 1, wherein the engagement portion is configured to avoid contacting the base when the latch is rotated from a first position in the non-operation mode to a second position in the operation mode. 10. The disk drive of claim 1, wherein the latch comprises a magnetic portion that is manipulated to rotate the latch between the positions for the operation mode and the non-operation mode. 11. The disk drive of claim 1, wherein the pin comprises a tapered portion at an end of the pin that is received by the bore of the base. 12. An actuator latch, for limiting rotational movement of a disk drive actuator, the latch comprising: a coupling portion having an elongate member that is configured to be received by a bore in a disk drive base, the coupling portion being configured to be rotatable about an axis defined by the elongate member when the elongate member is received by the bore of the base; andan engagement portion, integrally formed with the elongate member, extending in a direction transverse to the axis and configured to engage and limit rotation of a disk drive actuator. 13. The actuator latch of claim 12, wherein the latch further comprises a dome on a top portion and aligned along the axis, the dome providing an area of contact between the latch and a top cover of the disk drive. 14. The actuator latch of claim 12, wherein the elongate member and the coupling portion are molded as a single unit. 15. The actuator latch of claim 12, wherein the latch comprises a plurality of materials. 16. The actuator latch of claim 15, wherein the engagement portion comprises a different material than the elongate member. 17. The actuator latch of claim 12, wherein the engagement portion comprises a polymer. 18. A disk drive comprising: a disk drive base having a coupling portion, the coupling portion extending from the base and having a bore therein; anda latch comprising an integral pin formed therewith, the pin sized to be received within the bore of the coupling portion and to permit relative rotational movement between the latch and the base; the latch rotatable about an axis of rotation, when coupled with the coupling portion, between a first position, where the latch engages a portion of an actuator assembly for limiting rotational movement of the actuator assembly, and a second position, where the latch does not engage the actuator assembly or limit rotational movement of the actuator assembly. 19. The disk drive of claim 18, wherein the latch further comprises a dome on a top portion, aligned with the axis of rotation, the dome providing a point of contact between the latch and a top cover of the disk drive. 20. The disk drive of claim 18, wherein the latch contacts the base, at a portion of the latch other than a latch coupling portion, in one of the first and second positions and does not contact the base in the other of the first and second positions.
