Abstract

Claims (13)

1. A disk drive comprising:

an actuator comprising:

an actuator body defining an axis of rotation;

a coil;

a wrap-around support extending from the actuator body radially beyond the coil with respect to the axis of rotation without encircling the coil; and

a tang supported by the wrap-around support, the coil positioned radially between the tang and the axis of rotation;

wherein the actuator body, the wrap-around support, and the tang are all a single component comprising a metal material having material continuity rather than an assembly of subcomponents;

the disk drive further comprising a first crash stop, the actuator being rotatable between first and second positions, the tang being disposed at the first crash stop with the actuator in the first position;

wherein the first crash stop includes a latch, the tang including a latching element, the latching element being engaged with the latch with the actuator in the first position.

2. The disk drive of claim 1 wherein the latch is a ferromagnetic latch.

3. The disk drive of claim 1 wherein the latching element comprises a ferromagnetic metal material.

4. The disk drive of claim 1 wherein the actuator body, the wrap-around support, and the tang comprise aluminum.

5. The disk drive of claim 1 wherein the actuator comprises an actuator arm defining a longitudinal axis extending orthogonal to and through the axis of rotation, the tang being angularly positioned within 15 degrees of the longitudinal axis with respect to the axis of rotation.
