Abstract

A magnetic memory disk storage system has a pair of storage disks rotatably mounted in a housing. A head actuator assembly is pivotably mounted adjacent to the storage disks and includes a plurality of load beam assemblies for placing read/write heads adjacent to the disk surfaces. Each of the load beam assemblies has a load beam, a magnetic recording slider adjacent an outboard end of the load beam, an actuator arm welded to the inboard end of the load beam and two alignment ears on the actuator arm. A pivot bearing assembly extends through pivot holes through the load beam assemblies for pivotable support of the head actuator assembly. The load beam assemblies are clamped together with the alignment ears on all of the load beam assemblies being in alignment. A torque washer next to the nut which clamps the parts on the bearing assembly includes a hole for resisting torque and preventing twisting of the load beam assemblies. The head actuator assembly is assembled from its component parts in a comb which protects the load beam assemblies and sliders during assembly, testing and transport.
