ABSTRACT:
A recording disk device comprises a sheet-like magnetic disk medium having at least one recording surface, a jacket body enclosing the magnetic disk medium and having first and second inner surfaces faced to both surfaces of the magnetic recording medium, and upper and lower liners attached to the first and the second inner surfaces of the jacket body to remove fine dust adhered to the magnetic recording medium. The recording disk device further comprises upper and lower subsidiary liners each of which is attached to at least a part of each of the upper and the lower liners so that the magnetic disk medium rotated within the jacket body is interposed between the upper and the lower subsidiary liners with both surfaces of the magnetic disk medium kept in contact with the upper and the lower subsidiary liners. The jacket body has upper and lower shells parallel to each other with the upper and the lower liners attached thereto, respectively. The upper and the lower shells have inner surfaces faced to the upper and the lower subsidiary liners through the upper and the lower liners, respectively. At least one of the inner surfaces of the upper and the lower shells is provided with a recess for accommodating a bent portion of the magnetic disk medium when it is deformed or bent.
