Latest Patents

Shau Yann Lea holds a patent for a method titled "Head degradation characterization for a data storage device." This invention provides a method and apparatus for characterizing whether a head of a data storage device exhibits excessive performance degradation. The device includes a data transducing head adjacent to a recording medium, along with read channel circuitry that features a variable gain amplifier (VGA) and a gain control block. The gain control block supplies VGA gain control values to maintain the amplitudes of readback signals within a suitable range for the read channel circuitry. A baseline VGA gain control value is first obtained, after which the read channel is parametrically adapted to optimize read error performance. An adaptive VGA gain control value is then obtained, allowing for the determination of head degradation based on the magnitude of this value and the difference between the VGA gain control value and the baseline value.
