Disk drive suspension in which a pivot center of a slider can be matched with a position of a supporting protrusion when a microactuator element is driven

摘要

A gimbal portion of a flexure is provided with first supporting portions to which first end portions of microactuator elements are secured and second supporting portions to which second end portions are secured. A first tongue portion is formed between the pair of first supporting portions. A leading-side portion of a slider is movably disposed on the first tongue portion. A second tongue portion is formed between the pair of second supporting portions. A trailing-side portion of the slider is secured to the second tongue portion. A narrow hinge portion is formed between the first and second tongue portions. The tongue portions are pivotably connected by the hinge portion. The distal end of a dimple contacts the hinge portion at a point of contact.

主权项

1. A disk drive suspension which comprises a load beam and a flexure comprising a stationary part secured to the load beam and a gimbal portion on which a slider is mounted, the disk drive suspension further comprising:
a pair of microactuator elements disposed on either side of the slider and each comprising a first end portion and a second end portion; a pair of first supporting portions of the gimbal portion to which the pair of first end portions are individually secured and supported by the stationary part; a pair of second supporting portions of the gimbal portion to which the pair of second end portions are individually secured; a first tongue portion which is formed between the pair of first supporting portions and on which a leading-side portion of the slider is disposed for movement; a second tongue portion which is formed between the pair of second supporting portions and to which a trailing-side portion of the slider is secured; a hinge portion which is formed between the first and second tongue portions, is narrower than the tongue portions, and pivotably connects the tongue portions; and a supporting protrusion swingably supporting the hinge portion relative to the load beam.
