1. A disk device comprising:
a magnetic disk having a recording surface;
a load beam rotatable around a rotation axis;
a first protrusion protruding from the load beam away from the rotation axis in a first direction orthogonal to the rotation axis;
a flexure including an attachment part attached to the load beam, and a mounting part rotatably supported by the first protrusion with respect to the attachment part;
a slider mounted on the mounting part, including:
a first element configured to read and write information from and to the magnetic disk, and
a floating surface configured to face the recording surface when the first element reads and writes information from and to the magnetic disk; and
a second element attached to the slider apart from a geometric center of the floating surface in the first direction, wherein
on a projection plane as viewed in a direction orthogonal to the floating surface, a contact position between the first protrusion and the mounting part is located between a geometric center of the slider and a center of gravity of the second element.
