Miniature hard disk drive system

PCT No. PCT/GB93/02366 Sec. 371 Date Aug. 3, 1995 Sec. 102(e) Date Aug. 3, 1995 PCT Filed Nov. 17, 1993 PCT Pub. No. WO94/11877 PCT Pub. Date May 26, 1994The present invention relates to a miniature hard disk drive system including a substantially sealed enclosure housing a head-disk assembly and a printed circuit board assembly. The head-disk assembly includes a rotary drive motor and an actuator assembly which pivotally supports and positions one or more read-write head flexure assemblies. In one aspect of the invention, the drive system includes two miniature hard disks having an outer diameter of between 40 mm and 50 mm and has a total thickness not exceeding 10.5 mm. In another aspect, the printed circuit board assembly has first contact pads and the head-disk assembly has a flexible circuit assembly with a first flexible portion connected to the actuator assembly for electrical connection to the read-write heads and with a second flexible portion having second contact pads. A miniature elastomeric connector is mounted in an aperture in a planar side wall of the enclosure for providing a low current capacity electrical connection between the first and second contact pads for facilitating data transmission between the read-write heads and the printed circuit board assembly. In addition, the miniature elastomeric connector provides a high current capacity electrical connection between the printed circuit board assembly and the rotary drive motor of the head-disk assembly.\!
