Method for manufacturing a magnetic disk comprising a glass substrate

摘要

A method for manufacturing a glass substrate for use in magnetic disk manufacturing comprises the steps of a) forming a glass sheet; b) forming a protective sheet over one or both sides of the glass sheet; c) cutting the glass sheet into workpieces; d) cutting the workpieces into disk-shaped substrates; 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.
