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 suspension for disc drive having a micro actuator mechanism comprises a base plate, a connecting plate having a hinge portion thinner than the base plate, a load beam provided with a flexure, a pair of actuator elements such as PZT, etc. The micro actuator mechanism includes a pivot portion formed between a pair of slits and support walls formed on the connecting plate. The actuator elements are provided individually on the opposite sides of the pivot portion. Each support wall is a bent portion that is formed by raising an edge portion of the connecting plate in the thickness direction of the main portion of the connecting plate.
