  • Method for predicting and improving wear characteristics of laser textured bumps formed on magnetic recording disk
    Patent number: 5987391
    Abstract: A method for predicting total bump height reduction from volume wear rate data for a laser textured magnetic disk. In this method, a bump topography function, r(h), is first established by which the bump half-width, r, is expressed as a function of bump depth, h. Then the bump height depth after first revolution, h.sub.1, is calculated according to the following equation: ##EQU1## Based on the observation of constant wear volume per cycle, the bump height depth after each subsequent revolution, h.sub.i, i=2 . . . N, is calculated according to the following equation: ##EQU2## The so-calculated h.sub.N is the total bump height reduction after the Nth revolution.
