Latest Patents

Hobson holds a patent for the "Detection of mechanical defects in a disc drive using injected test." This invention discloses a method and apparatus for testing mechanical defects during the manufacturing process of disc drives. The technique involves exciting resonances in the disc drive by injecting a sinusoidal test signal into the servo position error (SPE) signal. This modified SPE is then sampled and filtered to characterize the test frequency, which is compared to the incoming SPE. If the gain exceeds predetermined criteria, an error flag is set, indicating a failure condition for the disc drive. This innovation allows for the identification of defects early in the manufacturing process, enabling timely remedial actions.
