Abstract

A magnetic tape cartridge reel includes a hub having a first end and a second end configured to receive a magnetic tape to be wound thereon and at least one flange which is attached to at least one of the first end and the second end of the hub, wherein the at least one flange is formed separately from the hub and is made of a flexible material.

Claims (28)

1. A magnetic tape cartridge reel comprising:

a hub having a first end and a second end configured to receive a magnetic tape to be wound thereon, and an inner hole extending between the first end and the second end;

at least one flange which is attached to at least one of the first end and the second end of the hub, wherein a diameter of an aperture of the at least one flange is the same as a diameter of the inner hole; and

at least one ring portion disposed on an outer surface of the at least one flange so as to be positioned along an outer perimeter of the at least one flange, so that a shape of an outer perimeter of the at least one ring portion is the same as a shape of the outer perimeter of the at least one flange, a diameter of an aperture of the at least one ring portion being larger than the diameter of an aperture of the at least one flange,

wherein the at least one ring portion has a greater specific gravity than the at least one flange.

2. The magnetic tape cartridge reel as set forth in claim 1 ,

wherein said at least one ring portion is concentric with the outer perimeter of the at least one flange.

3. The magnetic tape cartridge reel as set forth in claim 1 ,

wherein the at least ring one portion has one of a shock proof and shock-absorbing function.

4. The magnetic tape cartridge reel as set forth in claim 1 ,

wherein said at least one ring portion comprises a single unit having an outer perimeter substantially similar to the outer perimeter of the at least one flange.

5. A magnetic tape cartridge reel comprising:

a hub having a first end and a second end configured to receive a magnetic tape to be wound thereon;

at least one flange which is attached to at least one of the first end and the second end of the hub; and

at least one ring portion disposed on an outer surface of the at least one flange so as to be positioned between an outer perimeter of the at least one flange, and an aperture of the at least one flange, wherein the at least one ring portion is made of foam material.

6. A magnetic tape cartridge reel, comprising:

a hub having a first end and a second end configured to receive a magnetic tape to be wound thereon, and an inner hole extending between the first end and the second end;

at least one flange which is attached to at least one of the first end and the second end of the hub, wherein a diameter of an aperture of the at least one flange is the same as a diameter of the inner hole; and

at least one ring portion disposed on an outer surface of the at least one flange so as to be positioned along an outer perimeter of the at least one flange, so that a shape of an outer perimeter of the at least one ring portion is the same as a shape of an outer diameter of the outer perimeter of the at least one flange, a diameter of an aperture of the at least one ring portion being larger than the diameter of the aperture of the at least one flange,

wherein the at least ring one portion has one of a shock proof and shock-absorbing function, and

wherein the at least one ring portion is made of a material different from a material of the at least one flange.

7. A magnetic tape cartridge reel comprising:

a hub having a first end and a second end configured to receive a magnetic tape to be wound thereon;

at least one flange which is attached to at least one of the first end and the second end of the hub; and

at least portion disposed on an outer surface of the at least one flange so as to be positioned along an outer perimeter of the at least one flange, so that an outer diameter of an outer perimeter of the at least one ring portion corresponds to an outer diameter of the outer perimeter of the at least one flange, a diameter of an aperture of the at least one ring portion being larger than a diameter of an aperture of the at least one flange,

wherein the at least ring one portion has one of a shock proof and shock-absorbing function, and

wherein the at least one ring portion is made of a material different from a material of the at least one flange,

wherein the at least one ring portion is made of foam material.
