ABSTRACT:
Disclosed is a hermetically sealed mobile hard disk drive that combines high storage capacity and performance with low power consumption and portable operation. The key enabling component of the mobile storage device is an integrated base ceramic substrate upon which a plurality of spiral conductors, MR stripes and interconnect conductors have been fabricated by a semiconductor process, and upon which electronic integrated circuits have been assembled. A single or dual rotor spindle assembly, a multi-arm actuator assembly and a ceramic housing are assembled with the integrated base forming a chamber that is hermetically sealed and can be filled with a low viscosity gas at ambient pressures or below.
