IPC: G11B5/82
Filed: 1995-10-31
Abstract: PROBLEM TO BE SOLVED: To prevent the dusting by sanding or grinding a glass plate formed into a disklike shape and then treating the whole glass substrate with a treating liquid of hydrosilicofluoric acid. SOLUTION: An aluminosilicate glass, etc., is cut and worked to form a disklike glass substrate and both the surfaces of the glass substrate are ground with a diamond grindstone. A hole is then bored in the central part of the substrate with a cylindrical grindstone to carry out the chamfering of the end faces on the outer and inner peripheries. The substrate is then lapped with a grindstone such as #400 or #1100 to provide about 4μm surface roughness. The resultant substrate is dipped in hydrosilicofluoric acid at 0.01-10wt.% concentration at about 10-50 deg.C for about 1-3min. The dipped substrate is further washed with a neutral detergent and water and the surface roughness of the end faces of the outer and inner peripheries is regulated to about 2μm.  The grinding step with a polishing liquid and the washing step with the hydrosilicofluoric acid are repreated to afford a prescribed surface roughness. The resultant substrate is dipped in a chemical strengthening solution prepared by heating and melting a mixture of KNO3 /NaNO3 and the whole surface is chemically strengthened and then washed with warmed sulfuric acid to provide a glass substrate for magnetic disks.
