Abstract
A magnetic transducer head adapted for flying on a fluid atmospheric bearing and a gimbal mounting device comprising a spring structure including an inner spring element secured to the head for inhibiting movement thereof in directions parallel with a plane therethrough and including an outer spring element coupled to the inner element and adapted to restrain rotation movement of the head about a pivot point thereon, the inner element being oriented in a plane coextensive with the line through the center of mass of the head and the head having a load point approximating the center of mass.
Claims7
In combination:
- a transducer head constructed and arranged for flying on a fluid bearing in close proximity to a transducing surface;
- gimbal supporting means to which said head is mounted for flyng so as to provide flexural freedom of rotation of said head around predetermined axes parallel to said surface while restraining rotation of said head about an axis perpendicular to said surface and also restraining motion of said head in a direction parallel to said surface;
- and
- head actuating means for applying a loading force to said head to urge said head toward said surface in a direction perpendicular thereto, said actuating means contacting said head in a plane which is coplanar with the center of mass of said head and parallel to said surface.
