Abstract
The invention presents a magnetic recording disc cartridge with two small fabric liners affixed inside the media compartment. One liner covers the lifter and the other covers the raised structure. The lifter and the raised structure bring the liners in contact with the flexible surface of the disc as it rotates, thus cleaning the disc. One or more protrusions in the media compartment prevent the disc from abrading the surface of the media compartment.
Claims24
A data storage cartridge comprising:
- a magnetic recording disc including a flexible surface;
- a first shell and a second shell including inner surfaces that define a media compartment to accommodate the magnetic recording disc;
- a fabric liner secured to one of the first shell and the second shell within the media compartment;
- and
- a protrusion on at least one of the inner surfaces, the protrusion making contact with the magnetic recording disc and forcing the magnetic recording disc away from the inner surface,
- wherein the area of the fabric liner is less than fifty percent of the area of the flexible surface of the magnetic recording disc.
An article of manufacture comprising:
- a magnetic recording disc including a flexible surface;
- and
- a shell defining a media compartment to accommodate the magnetic recording disc,
- wherein the shell includes a protrusion in the media compartment, the protrusion making contact with the magnetic recording disc and forcing the magnetic recording disc away from an interior surface of the media compartment, and
- wherein the shell includes a lifter secured to the inner surface of the media compartment.
A method comprising:
- providing a cartridge to enclose a magnetic recording disc, the cartridge including a media compartment with an inner surface;
- providing a protrusion in the media compartment;
- making contact between the magnetic recording disc and the protrusion to keep the magnetic recording disc from contacting the inner surface of the compartment;
- and
- providing at least one of a lifter and a raised structure secured to the inner surface of the media compartment.
A 3.5 inch (8.9 cm) form factor floppy magnetic recording diskette comprising:
- a magnetic recording disc including a flexible surface;
- a back shell;
- a cover shell configured to be joined to the back shell, wherein the back shell and the cover shell define a media compartment, having interior surfaces, to accommodate the magnetic recording disc;
- a first fabric liner secured to the back shell within the media compartment;
- and
- a second fabric liner secured to the cover shell within the media compartment;
- wherein the area of each fabric liner is less than fifty percent of the area of the flexible surface of the magnetic recording disc;
- wherein the back shell includes a first protrusion in the media compartment;
- wherein the cover shell includes a second protrusion in the media compartment;
- and
- wherein the protrusions force the magnetic recording disc away from the interior surfaces of the media compartment.
A data storage cartridge comprising:
- a magnetic recording disc including a flexible surface;
- a first shell and a second shell including inner surfaces that define a media compartment to accommodate the magnetic recording disc,
- a lifter secured to at least one of the inner surfaces;
- and
- a fabric liner secured within the media compartment and interposed between the magnetic recording disc and the lifter,
- wherein the area of the fabric liner is less than fifty percent of the area of the flexible surface of the magnetic recording disc.
