Abstract
A head gimbal assembly includes a load beam, a wiring member including a metal plate disposed on the load beam, a magnetic head attached to a tip section of the wiring member, and a piezoelectric element that is fixed to and supported by supporting pads and deforms in response to a voltage applied thereto. The metal plate includes a tip section to which the magnetic head is fixed, and a base section that is spaced apart from the tip section and is fixed to the load beam. The supporting pads include first and second supporting pads proximate to the tip section and distal from the base section and a third supporting pad proximate to the base section and distal to the tip section, each of supporting pads separated from and independent of both the tip section and the base section.

A head gimbal assembly comprising:
- a load beam;
- a wiring member including a metal plate and an insulating layer disposed on the metal plate and the load beam, the metal plate including a tip section that is movable away from the load beam and a base section that is fixed to the load beam;
- a magnetic head electrically connected to a first wiring of the wiring member and attached to a tip section of the wiring member;
- and
- an expanding and contracting element that is fixed to supporting pads through the insulating layer and configured to deform in response to a voltage applied thereto through a second wiring of the wiring member, the supporting pads including first and second supporting pads proximate to the tip section of the metal plate and distal from the base section and third and fourth supporting pads proximate to the base section and distal from the tip section of the metal plate, the first and second supporting pads being structurally separated from and independent of both the tip section of the metal plate and the base section, and the third and fourth supporting pads being structurally connected to the base section.
A storage device comprising:
- a disk-shaped recording medium;
- a driving motor that supports and rotates the recording medium;
- and
- a head gimbal assembly including:
- a load beam,
- a wiring member including a metal plate and an insulating layer disposed on the metal plate and the load beam, the metal plate including a tip section that is movable away from the load beam and a base section that is fixed to the load beam,
- a magnetic head electrically connected to a first wiring of the wiring member and attached to a tip section of the wiring member, and
- an expanding and contracting element that is fixed to supporting pads through the insulating layer and configured to deform in response to a voltage applied thereto through a second wiring of the wiring member, the supporting pads including first and second supporting pads proximate to the tip section of the metal plate and distal from the base section and third and fourth supporting pads proximate to the base section and distal from the tip section of the metal plate, the first and second supporting pads being structurally separated from and independent of both the tip section of the metal plate and the base section, and the third and fourth supporting pads being structurally connected to the base section.
