Abstract: A disk drive system includes a base, a disk rotatably attached to the base, and an actuator assembly movably attached to the base. The actuator assembly moves the transducer to selected areas of the disk where information representative of data is to be written or read. The transducer is attached to the suspension. The arm has at least one suspension attached thereto using a wire wound sleeve or wrap. The wire wound sleeve or wrap surrounds the end of the arm and captures one or two suspensions between the arm and the wire wound coil. A transducer is attached to the suspension. The electrical connections between the arm and the suspension can also be made along with the mechanical connection of these two elements.

Abstract: An improved disc memory module design in which mechanical force to shift the data transducers and to rotate the discs is supplied through magnetic couplings to the module, thereby avoiding radial stresses created by mechanical couplings such as belts, splined connection shafts, gears, etc. The use of bearings at each end of the spindle and the head arm shaft also reduces the errors induced by radial stresses on the axis of the head arm shaft and spindle.
