Abstract
According to one embodiment, an actuator arm includes a joint, an extension, a pair of outer surfaces, and a linear protrusion. The joint is rotatably supported on a shaft. The extension extends from the joint and has a tip end connected to a head that performs at least reading or writing with respect to a rotating disk recording medium. The outer surfaces are in a front-and-rear relationship with each other. At least one of the outer surfaces faces the disk recording medium. The linear protrusion is arranged on and extends along an edge of at least one of the outer surfaces. The edge is located upstream on the outer surfaces in a flowing direction of an air flow generated by the rotation of the disk recording medium.
