ABSTRACT:
A low magnetic isolation closure glass for use in multitrack magnetic tape heads has been prepared by combining a specific lead borosilicate glass with a specific borosilicate glass in a 60/40 weight percent ratio. The glass formed from the combination exhibits compatibility with ferrite and has reduced wear. Controlling the anneal temperature regulates the residual stress of the closure glass produced, and thus, provides some control over the wear characteristics of the glass.
