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.
Claims29
A flexure comprising:
- a slider tongue with a proximal end and a distal end, the slider tongue including a leading edge at the proximal 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.
A flexure comprising:
- 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;
- at least one actuator affixed to the slider tongue, between the proximal end and the distal end;
- and
- at least one partial etched portion 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 actuator.
A load beam comprising:
- a mounting surface configured to receive a flexure;
- and
- one or more damping material at a location on the load beam to reduce an impact of non-operational shock event of the flexure impacting the load beam.
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,
- at least one actuator 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 to reduce stress on the at least one actuator;
- and
- a load beam including:
- a mounting surface configured to receive the flexure, and
- one or more damping material positioned at a location of where the slider tongue of the flexure contacts the mounting surface of the load beam during a non-operational shock event.
A load beam comprising:
- a mounting surface configured to receive a flexure;
- and
- one or more damping device at a location on the load beam to reduce an impact of non-operational shock event of the flexure impacting the load beam.
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
- one or more damping devices positioned at a location of where the slider tongue of the flexure contacts the mounting surface of the load beam during a non-operational shock event.
