Abstract: Disclosed is a mobile Integrated Battery Powered Hard Disk Drive (IBP-HDD) equipped with USB OTG capabilities for direct connection to other USB devices, such as cell phones, PDAs, MP3 players, GPS, digital camcorders, digital cameras and other devices. These drives come in all form factors and combine high storage capacity and performance with low power consumption and portable operation. One component of the integrated drives is the base upon which all components and assemblies of the HDD have been mounted to produce a Drive-On-A-Substrate. A cover mounts to the base and separates each component and assembly into isolated compartments that can be evacuated of air and refilled with inert gases for improved performance and reliability. A first embodiment of the invention involves a method to manufacture a base. A second embodiment of the invention involves a method to manufacture an integrated battery powered hard disk drive portion on a base.

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.

Abstract: The integrated planer motor assembly consists of two parts: a. A integrated planer stator assembly that combines the motors stator coils, biased MR sensors and the motor's variable speed control IC into a single part using advanced high volume semi-conductor manufacturing processes; b. A planer rotor assembly having a precise planer surface containing the high energy permanent magnet and the ceramic ferrite return structure. The rotor assembly is assembled to the stator assembly using a precision washer to establish the motors small and precise air gap thus maximizing magnetic flux density.

Abstract: Disclosed is a multiple rotary actuator assembly consisting of a plurality of modular actuators, wherein each modular actuator is mounted to and rotates independently about a common pivot shaft. Modular actuators consist of Integrated and Data arms, upon which multiple read/write transducers are mounted, for the recording and recovery of digital data. An integrated arm also contains a spiral conductor pattern that interacts with a multi-gap voice coil motor, to provide the necessary torque to rapidly position the modular actuator.

Abstract: A dramatic way to increase I/O performance, of a disk drive, is by the addition of another actuator to the disk drive. Dual-actuators allows the drive to overlap seeks, which produces a seamless stream of data to the host system by eliminating the breaks caused by conventional single actuators when they are repositioned.
