ABSTRACT:
In a magnetic disk driver for driving a magnetic disk inserted thereinto, a pair of locating members locates both ends of a guide bar to mount the guide bar on a main surface of a main frame in cooperation with a guide bar cramp. Disposed in the vicinity of a magnetic head, one of the locating members includes a projecting portion which projects on the main surface of the main frame. The projecting portion may be a projection squeezed out of the main frame by half blanking. Disposed over the main surface of the main frame and apart from the main frame, a head carriage holds a magnetic head movably along a predetermined radial direction to the magnetic disk. The head carriage comprises a head carriage body and a supporting frame for supporting the head carriage body. The supporting frame projects into the main surface of the main frame and is fitted on the guide bar. The main frame comprises a safe portion, which is opposed to the guide bar, for preventing contact of the supporting frame of the head carriage with the main surface of the main frame when the head carriage slides along the guide bar. The safe portion includes a concave portion. The concave portion may be dented by half blanking.
