Abstract

According to one embodiment, a disk device includes a first adhesive attaching a slider to a suspension. A flexure of the suspension includes an outer surface of a metal plate and an insulator. The insulator surrounds the first adhesive. The insulator includes two first walls, a second wall, and a third wall. The first walls extend closer to each other toward a axis of a carriage. The second wall is spaced apart from the first walls and further away from the axis than the first walls. The third wall is located at a center of the insulator in a circumferential direction and is located between the first walls and the second wall. The third wall is shorter than the second wall. The distance between the second wall and the third wall is shorter than a distance between the first walls and the third wall.

Dependent claims

A disk device comprising:

a magnetic disk;
a slider configured to read and write information from and to the magnetic disk;
a carriage configured to rotate about a rotation axis;
a suspension that is attached to the carriage;
and
a first adhesive that attaches the slider to the suspension, wherein
the suspension includes a base plate attached to the carriage, a load beam attached to the base plate, and a flexure attached to the load beam;
the flexure includes
a metal plate,
an outer surface of the metal plate to which the first adhesive adheres, and
an insulator located on the outer surface to surround at least a part of the first adhesive, the insulator including
two first walls extending closer to each other toward the rotation axis,
a second wall spaced apart from the two first walls and further away from the rotation axis than the two first walls, and extending across a center of the insulator in a circumferential direction about the rotation axis, and
a third wall located at least partially at the center of the insulator in the circumferential direction and located between the two first walls and the second wall, the third wall being shorter in length than the second wall in the circumferential direction;
and
a distance between the second wall and the third wall is shorter than a distance between each of the two first walls and the third wall.
