Abstract
A recording head for use in magnetic storage devices is disclosed. The recording head includes a transducer that is bi-directionally movable with respect to a surface of the magnetic storage medium, thereby enabling improved positioning of the transducer during recording head read and write operations. Various structures are disclosed to bi-directionally actuate the recording head transducer. In one embodiment, an interleaver assembly having a plurality of flexure assemblies employs a motor including magnetic portions for selective, bi-directional actuation. In another embodiment, electrostatic charges are employed in the flexure assemblies for selective actuation. In yet another embodiment, piezoelectric elements are included to provide for selective actuation.
Claims26
A recording head for use in a magnetic storage device having a magnetic medium, comprising:
- a slider body;
- a transducer body containing a transducer;
- an interleaver assembly comprising:
- first and second interconnect regions, the first and second interconnect regions connected to the slider body;
- a body portion having a central portion extending between the first and second interconnect regions, the body portion being connected to the transducer body;
- and
- first and second flexure assemblies that respectively interconnect the first and second interconnect region with the central portion;
- the first and second flexure assemblies each including:
- a plurality of resilient flexure beams that extend between and attach to a respective one of the first and second interconnect regions and the central portion;
- and
- a plurality of cantilevered beams that extend between a respective one of the first and second interconnect regions and the central portion, wherein each cantilevered beam is configured to be electrically charged to provide a motional force to selectively move at least one of the first and second flexure assemblies, wherein movement of at least one of the first and second flexure assemblies causes corresponding movement of the transducer with respect to both the slider body and a surface of the magnetic medium.
A recording head for use in a magnetic storage device having a rotating magnetic medium, comprising:
- a slider body;
- a transducer body containing a transducer;
- an interleaver assembly comprising:
- first and second interconnect regions, the first and second interconnect regions connected to the slider body;
- a body portion having a central portion extending between the first and second interconnect regions, the body portion being connected to the transducer body;
- and
- first and second flexure assemblies that respectively interconnect the first and second interconnect region with the central portion;
- the first and second flexure assemblies each including:
- a plurality of resilient flexure beams that extend between and attach to a respective one of the first and second interconnect regions and the central portion;
- and
- a plurality of cantilevered beams that extend between a respective one of the first and second interconnect regions and the central portion;
- wherein each cantilevered beam includes:
- a first end that attaches to one of the first interconnect region, the second interconnect region, and the central portion;
- and
- an unattached second end;
- wherein each cantilevered beam is interposed between nonconductive pairs of the flexure beams;
- wherein each cantilevered beam is configured to be selectively and electrically charged to provide a motional force to selectively move at least one of the first and second flexure assemblies, wherein selective movement of at least one of the first and second flexure assemblies causes corresponding movement of the transducer with respect to both the slider body and a surface of the magnetic medium.
A recording head for use in a magnetic storage device having a rotating magnetic medium, comprising:
- a slider body;
- a transducer body containing a transducer;
- an interleaver assembly comprising:
- a flexure assembly connected with the both slider body and the transducer body, wherein selective movement of the flexure assembly causes corresponding movement of the transducer with respect to both the slider body and a surface of the rotating magnetic medium, the flexure assembly including:
- a plurality of resilient flexure beams;
- and
- a plurality of cantilevered beam sets arranged between the pairs of the resilient flexure beams, wherein each set includes a first cantilevered beam and a second cantilevered beam, wherein each cantilevered beam is configured to be selectively and electrically charged to provide a motional force to selectively move the flexure assembly.
