Abstract

THE PRESENT INVENTION PROVIDES AN ABRASIVE COMPOSITION FOR POLISHING MAGNETIC RECORDING DISK SUBSTRATES THAT RESULTS IN A LOW SURFACE ROUGHNESS OF THE MAGNETIC RECORDING DISK, ALLOWS THE ATTAINING OF HIGH-DENSITY RECORDING WITHOUT THE OCCURRENCE OR PROTRUSIONS OF POLISHING SCRATCHES, AND ENABLES POLISHING TO BE PERFORMED AT AN ECONOMICAL SPEED. THE PRESENT INVENTION DISCLOSES AN ABRASIVE COMPOSITION FOR POLISHING MAGNETIC RECORDING DISK SUBSTRATES COMPRISING WATER, SILICON DIOXIDE, ANTIGELLING AGENT, ALUMINUM NITRATE AND HYDROGEN PEROXIDE.
