Abstract
A microfabricated slider assembly used in a disc drive is disclosed. The slider assembly has a slider body having a stator and a rotor, wherein the rotor and the stator are integrally formed from a single substrate. The rotor has a head supporting portion movable both laterally and vertically in relation to the stator to facilitate positioning the transducer head accordingly. The slider assembly also has a microactuator for actively moving the rotor. In one embodiment, the slider assembly has microactuators for actively moving the rotor both laterally and vertically.
Claims21
A slider assembly used in a disc drive for supporting a transducer head with respect to a rotatable disc, the slider assembly comprising:
- a slider body having a stator and a rotor, wherein the rotor and the stator are integrally formed from a single substrate, the rotor has a head supporting portion carrying the transducer head, and the head supporting portion of the rotor is movable in both vertical and lateral directions in relation to the stator;
- and
- microactuating means for laterally moving the head supporting portion of the rotor in relation to the stator.
A slider assembly used in a disc drive for supporting a transducer head with respect to a rotatable disc, the slider assembly comprising:
- a slider body having a stator and a rotor, wherein the rotor and the stator are integrally formed from a single substrate, the rotor has a head supporting portion carrying the transducer head, and the head supporting portion of the rotor is movable in both vertical and lateral directions in relation to the stator;
- and
- a first microactuator for laterally moving the head supporting portion of the rotor in relation to the stator.
A slider assembly used in a disc drive for supporting a transducer head with respect to a track of a rotatable disc, the slider assembly comprising:
- a slider body having a stator and a rotor, wherein the rotor and the stator are integrally formed from a single substrate, and the rotor has a head supporting portion carrying the transducer head thereon and a base portion connected to the head supporting portion, the rotor being movable in a first direction in relation to the stator and the head supporting portion of the rotor being movable in a second direction in relation to the base portion of the rotor;
- and
- a first microactuator for moving the rotor.
