Abstract
A method of calculating an amplitude decay rate of a magnetic storage medium. The method involves (a) writing a test track to the magnetic storage medium and measuring the initial amplitude of the test track to obtain a reference amplitude; (b) performing a DC erase on the test track; (c) measuring and storing the test track amplitude after step (b) together with a time at which the measurement was made; (d) writing a reference track; (e) measuring and storing the reference track amplitude after step (d); (f) repeating steps (b) to (e) until a DC erase amplitude decay rate has been established; and (g) calculating a normal amplitude decay rate for the magnetic storage medium from the DC erase amplitude decay rate.
