Magnetic head suspension having selected thicknesses for enhancing rigidity
 A magnetic head suspension for a magnetic memory apparatus includes a load arm having a head arm portion and a carriage arm portion that is thicker than the head arm portion. The load arm may include a first plate as the head arm portion, and a second plate attached to the first plate as the carriage arm portion. A magnetic head slider attaching part is gimbaled to the first plate, and is formed from the material of the first plate. The first plate is provided with a loading bend in an intermediate portion thereof to provide an added pushing force to the magnetic head toward the magnetic disk. A conductor layer is patterned in the underside of the first plate, to transfer signals to and from the head.
