ABSTRACT:
The object of this invention is, in magnetic disk surface texture processing by abrasive tape, to achieve uniformity of roughness of the processed surface by automatically adjusting the feed speed of the abrasive tape, and to increase productivity. It consists of a sensor unit that measures the processing state of the surface of a magnetic disk on which texture processing has been completed, a holding unit for rotating the magnetic disk during measurement, and a processing equipment that compares the measured values with predetermined processing conditions and again corrects the processing conditions when they depart from the set conditions, and it maintains stable processing accuracy.
