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.
