Abstract

Fixed abrasive lapping film process which utilizes the steps of absolute filtering with abrasive technology, establishing coating thickness greater than the largest particles to be embedded, embedding the particles by gravitational settling of abrasive particles, calendaring of the uncured abrasive coating. Fixed abrasive lapping films to finish the magnetic surface of rigid magnetic storage disks are improved by the following processes.
