Disc drive suspension
A disc drive suspension has a base portion including a baseplate and a plate member, a load beam, a pair of hinge members, and a flexure with conductors. The flexure passes through a gap between the hinge members and ranges over the load beam and the base portion. A thin-walled portion is formed by partial etching on that region of a front end portion of the plate member of the base portion which faces the flexure. A thin-walled portion is also formed by partial etching on that region of a rear end portion of the load beam which faces the flexure.
1. A disc drive suspension comprising:
a base portion including a baseplate;
a load beam formed independently of the baseplate;
a hinge member having a pair of spring portions situated between a front end portion of the base portion and a rear end portion of the load beam and fixed portions fixed overlapping the base portion and the load beam, individually;
a flexure with conductors which is located on those sides, obverse or reverse, of the base portion and the load beam on which the hinge member is lapped, passes between the spring portions, and ranges over the load beam and the base portion, and
a recess formed on that region of the front end portion of the base portion which faces the flexure with conductors; and/or a recess formed on that region of the rear end portion of the load beam which faces the flexure with conductors.
2. A disc drive suspension according to claim 1 , wherein the recess on the base portion is a thin-walled portion formed by reducing the thickness of a part of the front end portion of the base portion, and the recess on the load beam is a thin-walled portion formed by reducing the thickness of a part of the rear end portion of the load beam.
3. A disc drive suspension according to claim 1 , wherein the recess on the base portion is a notch formed on the front end of the base portion, and the recess on the load beam is a notch formed on the rear end of the load beam.
