Abstract
A suspension for a magnetic transducer including a normally flat gimbal spring in the form of a figure eight, with a pair of tabs or ears at the sides of the eight by means of which the spring is mounted; and a folded backup spring having legs extending from a mounting side to the other side and then back again, with a depending leg and flange portion effective to provide pressure on the center of the gimbal spring and transducer so that the backup spring provides resilient backup force against translation of the transducer on its main axis and the gimbal spring provides resilience against transducer pitching and rolling.
Claims6
A transducer suspension assembly comprising:
- a rigid support,
- a gimbal spring of thin flexible material attached to said support,
- a transducer fixed to and thereby supported and carried by said gimbal spring, and
- a backup spring of thin sheet spring material having a first leg fixed at one end thereof to said rigid support, a second leg connected serially with said first leg and folded back with respect to said first leg to permit flexure of said second leg in a pivotal direction opposite the pivotal direction of flexure of said first leg and a third leg connected serially with said second leg and folded back with respect to said second leg and having its distal end backing up said transducer and thereby applying a force on the transducer.
