Abstract
An actuator structure in which the arms which support the magnetic heads are of sheet material in back-to-back pairs having ends fitted into and clamped between the confronting faces of pads arranged in columns on an actuator body. The pads in each column are cantilevered from the body on deflectable supports, except for one rigid support substantially centrally positioned in each column. A bolt extending through axially aligned holes in the pads and the arms in each column applies pressure to deflect the pad supports and clamp the arms between the pads.
