Abstract
A suspension assembly for supporting a slider carrying transducer elements. The suspension assembly including a load beam and a device for adaptively adjusting the flexure of the load beam to adjust preload force supplied to the slider.
Claims15
A combination comprising:
- a head including at least one transducer element;
- a flexible load beam operably coupled to the head to supply a load force to the head;
- an amplifier supported on the flexible load beam;
- leads connecting the at least one transducer element on the head to the amplifier;
- and
- a thermally expandable member coupled to the load beam to flex the load beam by expansion of the thermally expandable member and the expandable member coupled to the amplifier and expandable by heat dissipated from the amplifier to flex the load beam to adjust the load force supplied to the head.
3 more elements
A combination comprising:
- an elongated flexible load beam;
- a head supporting at least one transducer element coupled to the flexible load beam so that the load beam supplies a load force to the head;
- an amplifier supported on the load beam and coupled to the at least one transducer element;
- and
- flexure adjusting means operably coupled to the amplifier and the load beam for selectively adjusting flexure of the load beam to adjust the load force to the head.
2 more elements
A method for operating a data storage medium comprising steps of:
- a. providing a slider to support a transducer element;
- b. providing a flexible load beam to support the slider relative to the data storage medium, the load beam adapted to provide a preload force to the slider;
- and
- c. supplying a signal to an amplifier coupled to the transducer element and supported on the load beam to adjust flexure of the load beam to adjust the preload force to the slider.
