Abstract
An apparatus for storing data includes a storage medium, a head assembly disposed in relation to the storage medium and operable to read and write data on the storage medium, an analog high pass filter operable to filter an output from the head assembly to yield a filtered analog signal, wherein a high pass corner frequency of the analog high pass filter is below a servo data frequency in the data, an analog to digital converter operable to sample the filtered analog signal to yield digital samples, and a digital filter operable to perform pole-zero compensation for the analog high pass filter on the digital samples to yield filtered digital samples, with a zero at the high pass corner frequency of the analog high pass filter, and with a pole at a frequency higher than the high pass corner frequency of the analog high pass filter.
