Appl. No.:

09/887600

Assignee:

Imation Corp. - Oakdale MN

International Classification:

B65C 100

US Classification:

156391, 156556, 156580, 156DIG 1, 156DIG 2

Abstract:

A CD label applicator kit including a case, a support device and an applicator tool. The case includes a base and cover that provides a label plate. The label forms an opening. The support device includes an alignment post, a hub and a spring. The alignment post is affixed to an outer wall of the cover and extends outwardly through the opening. The hub is slidably disposed about the alignment post and defines a disk-receiving surface. The spring biases the hub to a raised position in which the disk-receiving surface is above the label plate. Finally, the applicator tool forms a central passage sized for selective placement about the alignment post. In one preferred embodiment, the kit includes a label sheet pack and a software disk stored within the base, and a writing utensil secured to the cover.

Assignee:

Minnesota Mining and Manufacturing Company - St. Paul MN

International Classification:

G11B 2303

US Classification:

360133

Abstract:

A lifter for cleaning a flexible magnetic recording disc. The lifter forces a fabric liner on the inner surface of a cartridge toward the rotating disc. The perimeter of the lifter is configured so that the force profile of the lifter taken across the width of its leading edge is not characterized by sudden changes in force across its width. The lifter can include a cut-out region within the area of the lifter, the region being configured to increase the force applied by the lifter along the inner tracks of the magnetic recording disc. The lifter does not significantly increase the torque required to drive the disc. The invention also includes a method of cleaning a disc using the lifter described above.

Inventors:

Jon R. Clark - Minneapolis MN
John W. Swanson - Mahtomedi MN

Assignee:

Imation Corp. - Oakdale MN

International Classification:

G11B 2303

US Classification:

360133

Abstract:

A removable data storage cartridge having a releasable shutter assembly. The shutter assembly rotatably maintains a data storage media and includes a first half and a second half. In this regard, at least a portion of an outer periphery of the first half is configured to releasably engage at least a portion of an outer periphery of the second half. With this configuration, the first half can easily be disassembled from the second half for replacing the media if found to be defective. In one preferred embodiment, the shutter assembly further includes a hinge integrally formed with the first half and the second half for facilitating axial assembly of the first half to the second half.

Assignee:

Imation Corp. - Oakdale MN

International Classification:

G11B 370
G11B 584

US Classification:

369290

Abstract:

An optical data storage disc comprising a disc-shaped substrate and a centrally-located magnetizable hub. The disc has a central bore configured to receive a drive pin from an optical disc drive. The substrate has a recessed annular portion adjacent its center bore. The hub is provided within the recessed portion of the substrate. The central bore of the disc may be defined by the central bore of the hub alone, so that the diameter of the hub's bore is less than that of the substrate. In the alternative, the central bore of the disc may be defined in part by the inner bores of both the substrate and the hub, in which case those inner bores are of equal diameter. In either case, the thickness of the disc when measured at its inner portion, i. e. , in the area of the hub and recessed portion, is equal to the thickness of the substrate at the periphery thereof. By reducing the thickness of the hub area to that of the substrate itself, the number of discs that can be stored together in a fixed space can be increased, thereby increasing the potential storage capacity of an optical disc jukebox or magazine system.

International Classification:

G11B 582

US Classification:

360135

Abstract:

A rotating removable data storage device hub, such as a hub for a micro-floppy magnetic data storage disc, that has a core of plain carbon steel and a primary coating. The hub may also include a vapor corrosion inhibiting layer on the primary coating. The plain carbon steel can have about 0. 5% or less carbon. The primary coating can be tin, nickel, zinc, chrome, paints, epoxies, epoxy-urethanes, phenolic resins, and combinations thereof. The vapor corrosion inhibiting layer may include an amine to reduce the rate of oxidation of the plain carbon steel core.
