2110172 9222056 PCTABS00018 An improved low profile magnetic head disk assembly (28) is used with dynamic magnetic information storage devices or rigid disk drives. The HDA (28) includes a head mounted to a suspension, wherein the suspension base plate is an integral part of the actuator arm (34). Each actuator arm (34) is in close registration with a bearing (36). The actuator assembly positions the head in close proximity with the rigid disk (42) surfaces, with the actuator arms (34) positioned exterior to the disks (42) and not passing over the surface of the disks (42). The actuator arms (34) may be a single piece for each disk (42), two pieces (one for each suspension), or three pieces (two actuator arms and one spacer). The center line of the actuator(s), with or without the spacer, is at the center line of the disk, thus reducing the total HDA (28) height.
