Disk drive suspension

摘要

A microactuator element is disposed on a gimbal portion of a flexure. A first end of the element is secured to a first supporting portion by a first insulating adhesive. A second end is secured to a second supporting portion by a second insulating adhesive. A first conductor is disposed on the first supporting portion. A second conductor on the ground side is disposed on the second supporting portion. A first electrode is disposed on a first end of the element. A first electrically conductive paste is provided between the first electrode and the first conductor. A second electrode is disposed on a second end of the element. A second electrically conductive paste is provided between the second electrode and the second conductor.

1. A disk drive suspension which comprises a load beam and a flexure that is formed of a metal base made of a stainless steel plate and that comprises 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 formed of a part of the stainless steel plate to which the first end portions of the pair of microactuator elements are individually secured in a thickness direction of the stainless steel plate; a pair of second supporting portions formed of another part of the stainless steel plate to which the second end portions of the pair of microactuator elements are individually secured in the thickness direction of the stainless steel plate; a tongue on which the slider is mounted; a first conductor provided on each of the pair of first supporting portions; a second conductor provided on each of the pair of second supporting portions; a first electrode provided on at least an end surface of each of the first end portions of the pair of microactuator elements; a second electrode provided on at least an end surface of each of the second end portions of the pair of microactuator elements; an electrically insulating first adhesive which secures the first end portions of the pair of microactuator elements and the pair of first supporting portions of the stainless steel plate to one another respectively in the thickness direction of the stainless steel plate; an electrically insulating second adhesive which secures the second end portions of the pair of microactuator elements and the pair of second supporting portions of the stainless steel plate to one another respectively in the thickness direction of the stainless steel plate; a first electrically conductive paste which is provided between the first conductor and the first electrode on the end surface of each of the first end portion portions and which electrically connects the first electrode and the first conductor to each other; and a second electrically conductive paste which is provided between the second conductor and the second electrode on the end surface of each of the second end portions and which electrically connects the second electrode and the second conductor to each other.
