Latest Patents

Yeong Heng Tan 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 the VGA to nominally maintain amplitudes of readback signals obtained from the head within a selected range suitable for the remaining portions of 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 thereafter obtained, and head degradation is determined in relation to the magnitude of the adaptive VGA gain control value as well as in relation to a difference between the VGA gain control value and the baseline value. This patent highlights his innovative approach to improving data storage reliability.
