## Abstract

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.

## Claims

### Claim 1

A process for producing a magnetic disk cartridge comprising the steps of
moistening at least one liner to be attached to an inner surface of a cassette shell to face a magnetic disk rotatably encased in the cassette shell, thereby expanding the liner, and
attaching the moistened and expanded liner to the inner surface of the cassette shell.

### Claim 2 (depends on 1)

A process for producing a magnetic disk cartridge as defined in claim 1, wherein the step of moistening the liner includes moistening liner material to expand the material and cutting the liner from the material.

### Claim 3 (depends on 1)

A process for producing a magnetic disk cartridge as defined in claim 1, wherein the step of moistening of the liner includes cutting the liner from liner material and moistening the liner to expand it.
