Abstract: A suspension comprises a load beam, a base plate, and a hinge member. The hinge member has an end portion lapped and fixed on the proximal portion of the load beam, a base plate mounting portion lapped and fixed on the base plate, and flexible portions situated between the end portion and the base plate mounting portion. The flexible portions are situated individually on the opposite sides of an opening formed in the hinge member, and are elastically deformable in its thickness direction. An end portion of the base plate and the hinge member are fixed on each other by means of laser welds in positions near the flexible portions. The laser welds are formed individually in regions that extend in the axial direction of the hinge member from the flexible portions.

Abstract: An extending portion of a hinge member is formed having a first hole in which a first positioning pin can be inserted and a second hole in which a second positioning pin can be inserted. The first hole has an elongated shape that allows the extending portion of the hinge member to move relatively to the first positioning pin in a width direction. The second hole is a circular large hole that allows the extending portion to move relatively to the second positioning pin in the width direction and an axial direction. A third hole and a fourth hole are formed in a flexure. The third hole has an elongated shape that allows the flexure to move relatively to the first positioning pin in the axial direction. The fourth hole has an elongated shape that allows the flexure to move relatively to the second positioning pin.

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 comprises a baseplate having a boss portion, a beam portion with a flexure, and a hinge member. The hinge member includes a connecting portion that can bend in the thickness direction thereof between the baseplate and the beam portion. If the length of the suspension from a pivot portion on the distal end portion of the beam portion to the center of the boss portion is 14.5 mm, the thickness of the baseplate is 0.175 mm or greater, the width of the baseplate is 4.5 mm or greater, the length of the connecting portion of the hinge member is 0.7 mm or shorter, and the length of the baseplate is 5.04 mm or shorter.
