Abstract
Various embodiments of the present invention provide systems and methods for reducing low frequency loss in a magnetic storage device. For example, a data processing circuit is disclosed that includes an amplifier, two filters and a summation element. The amplifier provides an amplified output that is filtered using a first of the two filters to create a first filtered output. The first filtered output is then filtered using the second of the two filters to create a second filtered output. The summation element sums the first filtered output with the second filtered output to provide a pole altered output.
