Abstract:
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.
