Abstract
A data storage device is disclosed comprising a first disk surface, a first actuator arm, a first head connected to a distal end of the first actuator arm, an actuator, and a first coupler configured to couple the first actuator arm to the actuator. The first coupler is actuated in order to couple the first actuator arm to the actuator during at least part of a seek interval, and while the first actuator arm is coupled to the actuator, the actuator is moved in order to seek the first head over the first disk surface.
Claims14
A data storage device comprising:
- a first disk surface;
- a first actuator arm;
- a first head connected to a distal end of the first actuator arm;
- an actuator;
- a first coupler configured to couple the first actuator arm to the actuator;
- control circuitry configured to seek the first head over the first disk surface during a seek interval by at least:
- actuating the first coupler in order to couple the first actuator arm to the actuator during at least part of the seek interval;
- while the first actuator arm is coupled to the actuator, moving the actuator in order to seek the first head over the first disk surface;
- and
- actuating the first coupler to decouple the first actuator arm from the actuator.
