METHOD FOR MANUFACTURING A MAGNETIC DISK COMPRISING A GLASS SUBSTRATE

摘要

A method for manufacturing a glass substrate (110) for use in magnetic disk manufacturing comprising the steps of a) forming a glass sheet (100); b) forming a protective sheet (102a, 102b) over one or both sides of the glass sheet; c) cutting the glass sheet into workpieces (104); d) cutting the workpieces into disk-shaped substrates (110); e) subjecting the edges of the substrates to an edge polishing process; and f) removing the protective layer. Of importance, by leaving the protective layer over the substrate, the substrate surface is protected from damage.
