Suspension assembly having reinforced end-tab and actuator for disk drive adopting the same

An actuator for a disk drive, comprising:

• a swing arm pivotally mounted on a base member of the disk drive;
• a suspension assembly elastically biasing a slider toward a surface of a disk, a read/write head to reproduce/record data being mounted on the slider;
• and
• a voice coil motor that rotates the swing arm to move the read/write head to a predetermined position of the disk,
• wherein the suspension assembly comprises:
• a load beam coupled to a first portion of the swing arm of the actuator,
• a flexure that supports the slider, the flexure having a first end portion fixed to a disk facing surface of the load beam and a second end portion extended toward a first end portion of the load beam, and
• an end-tab having an inner periphery and an outer periphery both extending linearly and substantially parallel to each other from the first end portion of the load beam, the end-tab being supported by a ramp arranged in an outside of the disk when the head is parked, and
• wherein the end-tab is angled away from a longitudinal central axis of the load beam such that a free end of the end-tab is deflected way from a center of the disk with respect to the longitudinal central axis while extending from the first end portion of the load beam, thereby increasing both vertical and horizontal stiffness of the end-tab.

A suspension assembly of an actuator of a disk drive, comprising:

• a load beam extending from a swing arm of the actuator and having an aperture therethrough and a dimple extending in a first direction;
• a flexure connected to the load beam, elastically biased in the first direction by the dimple, and having a limiter extending through the aperture to engage the load beam, to limit travel of the flexure in the first direction;
• and
• an end-tab extending from an end of the load beam at an angle away from a longitudinal central axis of the load beam to engage a ramp during parking of the actuator, wherein a free end of the end-tab is deflected away from a center of the disk with respect to the longitudinal central axis, while extending from the end of the load beam.
