In this paper we present an automated technique of extracting the 2D readback waveforms from the spinstand especially for the evaluation of the servo pattern. The setup is tested with commercial media mounted on a Guzik spinstand. The raw readback data is acquired, processed and averaged to get the image of the servo region with high signal to noise ratio (SNR). Based on the 2D readback signal captured...
