ABSTRACT:
A magnetic transducer support assembly includes parrallel flexure spring supporting elements which are of sufficient length to approximate linear motion over the length of translational displacement used. The flexures are formed of a single continuous length of flat spring material, and built-up portions on the spring stretches between the base member and transducer carriage are provided to resist twisting and other unwanted motions induced by vibration and similar influences. Displacement is achieved by cam actuation driven by a stepper motor which may control multiple such transducer mountings on a single side of a disk or on opposite sides of a disk.
