Abstract
A flexure design is provided that can focus the lifting force on a slider device at its leading edge. For sub-ambient pressure sliders, this results in an rapid increase in pressure in the sub-ambient pressure area causing the slider device to quickly lift off from the disk surface in a ramp unload disk drive. In one embodiment, first and second outriggers are provided in the flexure that each include a section that extends distally and a section that extends proximally. The sections of the outriggers that extend proximally can be joined and coupled to a tab section slider which would be located at the leading edge of the slider.
Claims20
A flexure comprising:
- a flexure body;
- first and second outriggers coupled to said flexure body, each including:
- a first section extending in a generally distal direction from said flexure body;
- and
- a second section coupled to said first section and extending in a proximal direction.
A flexure comprising:
- a main body;
- a neck portion coupled to a proximal portion of said main body;
- and
- a tab portion coupled directly to said neck portion.
A head suspension assembly comprising:
- a flexure including
- a flexure body;
- first and second outriggers coupled to said flexure body, each including:
- a first section extending in a generally distal direction from said flexure body;
- and
- a second section coupled to said first section and extending in a proximal direction;
- and
- a slider coupled to said flexure.
A disk drive comprising:
- a disk adapted to be rotated;
- and
- a flexure including
- a flexure body;
- first and second outriggers coupled to said flexure body, each including:
- a first section extending in a generally distal direction from said flexure body;
- and
- a second section coupled to said first section and extending in a proximal direction;
- and
- a slider coupled to said flexure and adapted to fly above said rotating disk.
