Abstract
A flexure is described herein. The flexure includes a slider tongue with a proximal end and a distal end. The sliding tongue including a leading edge at the proximal end prone to contact an undersurface of a load beam attached to the flexure. The flexure also includes a magnetic read/write head slider attached to the slider tongue at the distal end, at least one PZT microactuator affixed to the slider tongue, between the proximal end and the distal end, and at least one dampening device at the leading edge of the slider tongue configured to reduce an impulse during a non-operational shock event and reduce stress on the at least one PZT microactuator.
Claims2
A suspension comprising:
- a flexure including:
- a slider tongue with a proximal end and a distal end, the slider tongue including a leading edge at the proximal end,
- a magnetic read/write head slider attached to the slider tongue at the distal end, and
- at least one actuator affixed to the slider tongue, between the proximal end and the distal end;
- and
- a load beam including:
- a mounting surface configured to receive the flexure, and
- at least two dampening devices positioned at locations of where the slider tongue of the flexure contacts the mounting surface of the load beam during a non-operational shock event, wherein each of the at least two dampening devices comprise first portion curved upwards away from the slider tongue and a second portion curved downwards toward the slider tongue.
