Abstract
A hard disk drive having an actuator coupled to a pivot part about which the actuator rotates, including first and second pivot bearings coupled to the actuator and the pivot part, wherein a rotation center of at least one of the first and second pivot bearings is offset from respective longitudinal centers of the first and second pivot bearings.
Claims21
A hard disk drive comprising:
- an actuator provided with a magnetic head;
- a pivot shaft to which the actuator is coupled and which forms a rotation axis of the actuator;
- and
- first and second pivot bearings each internally including rotation balls forming a rotation center and coupled to the pivot shaft to assist rotation of the actuator;
- wherein at least one of the first and second pivot bearings is configured as an asymmetric pivot bearing having the rotation balls provided at a preset distance from a central axis line in a thickness direction of the asymmetric pivot bearing.
