Abstract :
We present a Monte Carlo simulation of inductive recording heads with a PRML recording channel. We show the effects of various head parameters such as gap length, throat height, track width, pole thickness, pulse undershoot and flying height on signal to noise (SNR) and bit error rates. The analysis shows a strong dependency of bit error rate on flying height, track width and pulse undershoot
