Claim 11:
12. A disk device comprising:
a plurality of magnetic disks each having a recording surface;
a first head gimbal assembly including
a first magnetic head configured to read and write information from and to a first magnetic disk of the plurality of magnetic disks,
a first load beam supporting the first magnetic head, and
a first base plate connected to the first load beam;

a first damper including
a first viscoelastic material, and
a first member attached to the first viscoelastic material and having higher rigidity than the first viscoelastic material; and

a carriage configured to rotate about a rotation axis to move the first magnetic head along the recording surface of the first magnetic disk, the carriage including
an arm,
a first fixation surface of the arm, the first fixation surface configured to face the recording surface of the first magnetic disk and to which the first base plate is fixed, and
a second fixation surface of the arm, the second fixation surface configured to face the recording surface of the first magnetic disk and to which the first viscoelastic material is fixed, wherein in a direction along the rotation axis, a distance between the first magnetic disk and the first fixation surface is less than or equal to a distance between the first magnetic disk and the second fixation surface.
