摘要： 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.

摘要： A suspension for disc drive comprises a base portion, a beam portion formed of the same material as the base portion and made thinner than the base portion by partial etching, and a hinge member connecting the base portion and the beam portion to each other. In manufacturing this suspension, a platelike semi-finished suspension, which integrally includes a base portion, a beam portion, and a connecting portion connecting the base portion and the beam portion to each other, is first manufactured. The thickness of the beam portion of the semi-finished suspension is reduced by partial etching. Thereafter, the base portion and the beam portion are connected by means of the hinge member, and moreover, the connecting portion is separated from the base portion and the beam portion.

摘要： A head suspension restricts deformation of a flexure caused by frictional force produced between a hard disk and a slider when the hard disk turns in a reverse direction. The head suspension has a load beam resiliently supported with a base. The base is supported with an arm that is turned around an axis. The load beam applies load onto a head having a slider to write and read data to and from the hard disk. The flexure is attached to the load beam and has a tongue that supports the slider. The flexure is provided with a limiter that limits displacement of the tongue due to frictional force produced between the hard disk and the slider when the hard disk is reversely turned. The limiter is on the base side and faces a free end of the tongue. The limiter is integrally formed from a part of the flexure, to face the free end of the tongue.

摘要： A carriage for a disc device, which has a top arm, bottom arm, and mid arm, has a main mode, end arm mode, and mid arm mode as a frequency response obtained when subjected to a vertical shake. In the main mode, all of the top, bottom, and mid arms swing at a first frequency within the same phase in a primary bending mode. In an end arm mode, the top and bottom arms swing at a second frequency higher than the first frequency within opposite phases and with an amplitude larger than that of the mid arm. In the mid arm mode, the mid arm swings at a third frequency having a difference of 50 Hz or less from the second frequency within the same phase as in the main mode, and the top and bottom arms swing within the phase opposite from that in the main mode.
