Abstract: A spring actuated magnetic head positioning system mounted upon an arm extending over the surface of a rotatable magnetic disk is disclosed for advancing the magnetic head into its operating position adjacent the magnetic surface. The spring positioning mechanism is contained within a housing, one end of which resiliently supports the magnetic head. The other end of the housing supports a remotely controlled actuator for actuating the spring positioning mechanism. The spring positioning mechanism is preloaded and held within a fixed and predetermined compressed length when retracted. In its operating position, the spring is translated toward the magnetic disk and further compressed to provide the force necessary to hold the magnetic head in position against the opposing force produced by the air pressure existing between the magnetic head and the rotating magnetic disk.

Abstract: A pneumatic actuating device for a magnetic recording head for a disk memory file or the like is described. Pneumatic pressure is brought to the actuator by an air supply tube which is held in place and also sealed by an O-ring surrounding the tube and compressed between a flat surface and a conical surface so as to squeeze inwardly on the outside wall of the tube. Pneumatic pressure within the assembly acts on a diaphragm to which a rigid disk is attached, and the disk acts on one end of a pin, the other end of which actuates the recording head.

Abstract: A manifold for use in positioning magnetic transducers adjacent a rotating disc coated with a magnetic material. A pressure source communicates with two or more transducers through the manifold to advance the transducers toward the disc surface to provide proper spacing between the transducers and the surface. Separation between the disc and transducers is maintained by an air bearing created at the surface of the rotating disc.
