ABSTRACT:
Various embodiments of the present invention provide systems and methods for using data equalization. For example, various embodiments of the present invention provide storage devices that include a semiconductor device having an equalization unit and a digital-to-analog converter, a read/write head assembly located in close proximity to the semiconductor device, and a control unit located less proximate to the read/write head assembly than the semiconductor device.
