The traditional tests used by disk manufacturers for accelerated wear and durability measurement of the magnetic disk surface are the start/ stop and accelerated wear tests. In both tests it takes days to weeks to get useful data. Thus, for the quality control of the manufacturing process and for the development of new types of surface coatings, there has been a great need for a tester which could do wear testing in much shorter times. A new tester has been designed and built which does the wear and durability testing in less than ¼ hour. The results obtained from this test correlate well with the traditional tests. This new tester, called the OSCILLATORY WEAR TESTER, uses coupons (2" x 1»") made out of disk material.
