ABSTRACT:
Different from a conventional casing for fixed disc memory assembly constructed by conjoining two covering members at the flanges by sandwiching a gasket prepared by punching a sheet of a spongy rubber, the invention proposes a covering member in which a gasket of a solid silicone rubber is adhesively and integrally bonded to the flange thereof in advance so that the fixed disc memory assembly can be constructed with greatly improved work-ability in addition to the advantage obtained by the absence of any tiny rubber particles formed by pubching of a spongy rubber sheet as the dusts to cause serious troubles. The gasket may be shaped either by a conventional rubber molding method and bonded to the flange using a silicone-based adhesive or may be formed by the techniques of the so-called FIPG method.
