Abstract
In an apparatus of the type including a magnetic transducer head adapted for flying on a fluid bearing in close proximity to a transducing surface and a gimbal apparatus to which the head is mounted for flying so as to provide flexural freedom of rotation of the head around roll and pitch axes parallel to the transducing surface and flexural freedom of translation in the direction of an axis perpendicular to the surface while restraining rotation of the head about the axis perpendicular to the surface and translation of the head in directions parallel to the surface, the gimbal apparatus comprising a thin, resilient, gimbal sheet having an external shape and interior openings defining an outer ring attachable to a gimbal sheet support at substantially opposite points on the outer ring and an inner ring spaced apart from the outer ring and attached to it by a pair of webs intersecting the outer ring at opposite interior edges between the points at which the outer ring is attached to the gimbal sheet support, the inner ring being attached to the transducer head at a point between the two webs, there is disclosed an improvement wherein both of the outer and inner rings have material r…
