Abstract: A suspension for disc drive comprises a base plate, a load beam attached to the base plate, and a flexure attached to the load beam. The load beam includes a rigid body portion, formed of a thick plate independent of the base plate, and a spring portion, formed of a spring member in the form of a thin sheet independent of the rigid body portion. The spring member connects the rigid body portion and the base plate. The spring member is thinner than the rigid body portion and has a lower spring constant. The spring portion is more flexible than the rigid body portion.

Abstract: A pair of side rails with an L-shaped cross section are formed individually on the opposite side edge portions of a load beam. Each side rail includes a low rail portion and a high rail portion higher than the low rail portion. The low and high rail portions are situated in a region nearer to the distal end portion of the load beam with respect to its longitudinal direction than the center of gravity of the load beam.

Abstract: A suspension comprises a base plate, a load beam, and a hinge member. An extending portion is provided on the side of the hinge member. A step forming portion is formed between the base plate mounting portion and the extending portion. The step forming portion has a difference in level such that the extending portion is situated inside the base plate mounting portion with respect to its thickness direction. An end portion of the flexure fixed on the extending portion is situated inside the surface of the base plate mounting portion with respect to the thickness direction.

Abstract: A suspension for disc drive has a base portion including a base plate, a load beam, a pair of hinge members, a wired flexure, etc. The wired flexure has a metal base and a wiring portion on the metal base. The hinge members are fixed overlapping the rear end portion of the load beam and the front end portion of the base plate. The wired flexure extends through a gap between the hinge members and ranges over the load beam and the base plate.
