Abstract

An experiment investigation has been conducted into the dependence of the read signal on flying height and medium thickness, employing a technique that permits the study of the effect of flying height and medium thickness on the same disk using the same slider. For the range of flying height (50-250 μin) and medium thickness (0–70 µin) investigated, excellent agreement with theoretical predictions is seen to exist for the maximum signal amplitude and half-pulsewidth of isolated pulses. It is further seen that the 6-dB packing density, calculated from half-pulsewidth measurements of isolated pulses, agrees well with experimental results.
