  • Method and apparatus for determining equalized signal-to-noise ratio in a storage device
    Publication number: 20020054443
    Abstract: A method and data storage device determine an equalized signal-to-noise ratio in the storage device. The equalized signal-to-noise ratio is determined by generating an analog read signal, passing the read signal through an equalizer in the storage device, and sampling the equalized signal using an analog-to-digital converter in the storage device. The samples from the analog-to-digital converter are then used in the equalized signal-to-noise calculation.
