Abstract
A hard disk drive apparatus is disclosed which utilizes at least a pair of actuator assemblies each of which includes a plurality of separate actuator arms and spacers stacked on a tubular sleeve which is bearing supported on a stationary actuator shaft. The arms and spacers are preferably ceramic with head leads and preamplifiers carried on the arm. Each actuator stack has heads oriented in only one direction to minimize the spacing between the hard disks. The head disk assembly is built up on the baseplate by installation of layers of actuator arms, spacers and hard disks. The assembled head disk assembly is enclosed between the generally flat baseplate and a top plate by a peripheral housing therearound. The disks are rotated by a dual stator motor located between the baseplate and the top plate with one stator mounted to the baseplate and the other stator mounted to the top plate.
