Flexible magnetic disc cassette

摘要

A magnetic disc cassette has a casing for enclosing a magnetic disc therein and a shutter provided on the casing and slideably moveable to expose or cover a head access opening in the casing. The shutter is molded from a synthetic resin to have a generally U-shaped cross section and has opposed edges which closely approach each other and are separated by less than the width of the casing when the shutter is removed from the casing.
