Abstract
Embodiments of the present invention include A head suspension assembly for a data storage device comprising a load beam and a Femto flexure coupled to the load beam, wherein the Femto flexure is a laminate structure comprising a support layer, the flexure comprising a plurality of symmetrical flexure legs, each of the flexure legs substantially hourglass shaped.
Claims15
A head suspension assembly for a data storage device comprising:
- a load beam;
- and
- a Femto flexure coupled to said load beam, wherein said Femto flexure is a laminate structure comprising a support layer, said flexure comprising a plurality of symmetrical flexure legs, each of said flexure legs substantially hourglass shaped wherein one of said plurality of flexure legs comprises two symmetrical tapers that meet at a substantially rectangular mid section to form a narrowest point of said flexure leg.
A data recording disk drive comprising:
- a disk with a data surface of concentric data tracks;
- a rotator for rotating the disk about an axis generally perpendicular to the disk;
- a slider maintained in operative relationship with the data surface when the disk is rotating;
- a transducer attached to the slider for reading data from and writing data to the data surface;
- an actuator for moving the slider generally radially to the disk to allow the transducer to access the data tracks;
- an electronics module for processing data read from and written to the data surface;
- and
- a suspension comprising a Femto flexure, wherein said Femto flexure is a laminate structure comprising a support layer, said flexure comprising a plurality of symmetrical flexure legs, each of said flexure legs substantially hourglass shaped wherein one of said plurality of flexure legs comprises two symmetrical tapers that meet at a substantially rectangular mid section to form a narrowest point of said flexure leg.
5 more elements
A Femto flexure for a data recording disk drive comprising:
- a laminate structure comprising a stainless steel or copper support layer;
- and
- a plurality of symmetrical flexure legs, each of said flexure legs substantially hourglass shaped wherein one of said plurality of flexure legs comprises two symmetrical tapers that meet at a substantially rectangular mid section to form a narrowest point of said flexure leg.
