Abstract
A shaft assembly of a rotary actuator arm structure in a rotary disc memory drive in which all machine operations cutting slots or openings for receiving leaf springs which provide axial and radial loads are performed along axes paralleling the axis of the rotary actuator. One leaf spring provides an axial load on the bearings of the shaft assembly. A second leaf spring fitted between one shaft bearing and the bearing housing thereat provides the radial bearing load.
