Abstract
A suspension includes a load beam having a main body and a transducer support element which is movable relative to the main body. A sheet of dielectric material extends along the load beam and carries a plurality of transducer signal traces and a coil. A microactuator is positioned along the load beam and includes a first magnet, the coil and a lever arm. The lever arm is secured to the transducer support element and supports one of the first magnet and the coil. The other of the first magnet and the coil is secured relative to the load beam.
Claims16
A suspension for supporting a transducer in a disc drive, the suspension comprising:
- a load beam having a main body;
- a transducer support element which is movable relative to the main body;
- a sheet of dielectric material extending along the load beam;
- a plurality of conductive transducer signal traces which are carried by the sheet;
- a coil which is carried by the sheet;
- and
- a microactuator positioned along the load beam and comprising a first magnet, the coil and a lever arm, wherein the lever arm is secured to the transducer support element and supports one of the first magnet and the coil, and wherein the other of the first magnet and the coil is secured relative to the load beam.
A suspension for supporting a transducer in a disc drive, the suspension comprising:
- a load beam having a main body portion and a transducer support portion which is attached to the main body portion through a flexural pivot;
- a sheet of dielectric material which extends along the load beam and carries a plurality of transducer signal traces and a coil;
- and
- a microactuator positioned along the load beam and comprising a first magnet, the coil and a lever arm, wherein the lever arm has a distal end secured to the transducer support element and a proximal end secured to one of the first magnet and the coil, and wherein the other of the first magnet and the coil is secured relative to the load beam.
A disc drive comprising:
- a data storage disc;
- and
- actuator means for positioning a transducer relative to the data storage disc and for carrying signals to and from the transducer.
