Abstract
A carriage assembly capable of suppressing flutter of actuator arms and magnetic disk is to be provided. In one embodiment, the carriage assembly comprises a first actuator arm having a windward side face, a leeward side face, an outer surface and an inner surface, and a second actuator arm having a windward side face, a leeward side face, a first inner surface opposed to the inner surface of the first actuator arm and a second inner surface positioned on the side opposite to the first inner surface. The first actuator arm is formed with a slant face extending from the windward side face toward the inner surface and the second actuator arm is formed with a slant face extending from the windward side face toward the first inner surface and a slant face extending from the windward side face toward the second inner surface.
