ABSTRACT:
A hermetically sealed mobile hard disk drive that combines high storage capacity and performance with low power consumption and portable operation, including an integrated base substrate. One embodiment is a method for fabricating an integrated base substrate with a plurality of spiral conductors, MR stripes, and interconnect conductors fabricated by a semiconductor process, and upon which electronic integrated circuits are later assembled. Various embodiments of the invention can support a single or dual rotor spindle assembly, a multi-arm actuator assembly, and a housing to form a hermetically sealed chamber with the integrated base substrate. Various embodiments of the invention can be filled with low viscosity gas at ambient pressure or a lower than ambient pressure.
