Method of grinding a substrate and method of manufacturing a glass substrate and a magnetic recording medium by the use of the glass substrate |
摘要 |
In a method of grinding side end surfaces of substrates, spacers are interposed between the substrates to form a stack of the substrates and the spacers. The spacers are slightly smaller in size than the substrates. The stack of the substrates and the spacers are ground by a rotatable brush or pad on the side end surfaces of the substrates so as to smooth chamfered portions of the substrates together with the side end surfaces.
