Abstract
According to one embodiment, a head suspension assembly includes a support plate including a proximal end portion, a distal end portion, a lift tab, and a first opening, a wiring member on the support plate, including a gimbal portion opposed to the distal end portion, and a head including a slider mounted on the gimbal portion, a head element on the slider, and a laser oscillator on the slider, opposed to the first opening. The support plate includes a first protrusion provided on the distal end portion and brought into contact with a central part of the slider via the gimbal portion, and a second protrusion that is provided between the first protrusion and the lift tab and that protrudes toward the gimbal portion.

A head suspension assembly comprising:
- a support plate including a proximal end portion, a distal end portion, a lift tab protruding from the distal end portion, and a first opening provided in the distal end portion;
- a wiring member provided on the support plate and including an elastically deformable gimbal portion opposed to the distal end portion of the support plate;
- and
- a head comprising a slider mounted on the gimbal portion, a head element provided at the slider, and a laser oscillator provided on the slider and opposed to the first opening, wherein
- the support plate includes a first protrusion provided on the distal end portion and brought into contact with a central part of the slider via the gimbal portion, and a second protrusion that is provided between the first protrusion and the lift tab and that protrudes toward the gimbal portion, the first opening and the laser oscillator being provided between the first protrusion and the second protrusion.
A head suspension assembly comprising:
- a support plate including a proximal end portion, a distal end portion, a lift tab protruding from the distal end portion, and a first opening provided in the distal end portion;
- a wiring member provided on the support plate and including an elastically deformable gimbal portion opposed to the distal end portion of the support plate;
- and
- a head comprising a slider mounted on the gimbal portion, a head element provided at the slider, and a laser oscillator provided on the slider and opposed to the first opening, wherein
- the support plate includes a first protrusion provided on the distal end portion and brought into contact with a central part of the slider via the gimbal portion and
- two second protrusions that are provided between the first protrusion and the lift tab and that protrude toward the gimbal portion, and
- the support plate has a central axis extending from the proximal end portion to the distal end portion, and the two second protrusions are provided on both sides of the central axis and apart from the central axis.
A disk drive comprising:
- a disk-shaped recording medium;
- and
- a head suspension assembly, comprising:
- a support plate including a proximal end portion, a distal end portion, a lift tab protruding from the distal end portion, and a first opening provided in the distal end portion;
- a wiring member provided on the support plate and including an elastically deformable gimbal portion opposed to the distal end portion of the support plate;
- and
- a head comprising a slider mounted on the gimbal portion, a head element provided at the slider, and a laser oscillator provided on the slider and opposed to the first opening, wherein
- the support plate includes a first protrusion provided on the distal end portion and brought into contact with a central part of the slider via the gimbal portion and
- two second protrusions that are provided between the first protrusion and the lift tab and that protrude toward the gimbal portion, and
- the support plate has a central axis extending from the proximal end portion to the distal end portion, and the two second protrusions are provided on both sides of the central axis and apart from the central axis.
