Process for producing magnetic disk cartridge

摘要

A process for producing a magnetic disk cartridge comprises the steps of moistening liners to be attached to inner surfaces of a cassette shell to face a magnetic disk rotatably encased in the cassette shell, thereby expanding the liners, and attaching the moistened and expanded liners to the inner surfaces of the cassette shell. Since the liners shrink upon drying, they remain taut irrespective of changes in the use environment.
