Abstract :
In all practical heads the gap deviates from straightness. Such irregularities reduce the output voltage. Assuming that a Gaussian distribution, of variance σ, describes the irregularities, the loss in output is shown to be 
dB. Inordinate losses are avoided if the variance in each head be less than 0.1λ.
