A suspension includes a multilayered plate member formed by at least three layers laminated together. The modulus of elasticity of neighboring layers of the at least three layers are different from each other. Both side edges of only a part of the layers of the multilayered plate member within a stiffness-required region are bent to form ribs.

摘要:
A complementary signal generator, for outputting complementary positive-phase and antiphase signals that vary between a first logical value and a second logical value, which includes a signal forming unit for outputting a positive-phase intermediate signal being in phase with an input signal varying between the first logical value and the second logical value, and an antiphase intermediate signal antiphase to the input signal. The generator also includes a first connecting means for simultaneously transferring the second logical value of the positive-phase intermediate signal and the first logical value of the antiphase intermediate signal to a positive-phase signal output part and an antiphase signal output part in synchronism with a state change of the input signal from the first logical value to the second logical value.

A suspension is provided, which comprises: a flexure with elasticity for supporting a head slider having at least one head element; a first load beam having first ribs for reinforcement at both side ends of the first load beam, for supporting the flexure; and a second load beam having second ribs for reinforcement at both side ends of the second load beam, at least a part of the second load beam being overlapped with the first load beam and being fixed to the first load beam, at least a part of the first and second ribs being overlapped with each other.
摘要:
A precise positioning actuator to be fixed to a head slider provided with at least one head element, for precisely positioning the at least one head element includes a base, and a pair of movable arms extending from the base and having slider fixing portions to be fixed to side surfaces of the head slider at top end sections thereof. Each of the pair of movable arms includes an arm member and an actuator layer formed on a side surface of the arm member, for displacing the arm member in response to a drive signal applied thereto. The actuator layer is terminated on the side surface of the arm member at a frontward position form the slider fixing portion.
