Abstract :
A special-purpose instrument was used to measure peak amplitude distributions in a rigid disk system employing thin-film heads and particulate disks. The distributions are attributed to Gaussian noise together with multiplicative defects whose sizes are exponentially distributed. The observed dependence of these distributions on track width is in reasonable agreement with this hypothesis. Information on the relative importance of various noise sources is also derived from these measurements.
