Abstract
A method of manufacturing a disc drive actuator is provided. The method includes manufacturing a disc drive actuator and machining a peripheral surface of the actuator. The peripheral surface is machined to obtain a desired profile dimension and thereby reduce variations in resonance characteristics from one actuator to the next.
Claims19
A method of manufacturing a disc drive actuator, comprising steps of:
- (a) manufacturing a disc drive actuator;
- and
- (b) machining a peripheral surface of the actuator.
A disc drive having an actuator manufactured according to a process comprising steps of:
- (a) manufacturing a disc drive actuator;
- and
- (b) machining a peripheral surface of the actuator to a desired profile dimension.
A disc drive comprising:
- a disc rotatable about a central axis;
- and
- actuator means for supporting and actuating a transducer relative to the disc and having a peripheral surface which is machined to a desired profile dimension within a tolerance that is defined for limiting variations in resonance characteristics of the actuator means.
