Media cartridge having reel suspension system and method of manufacture
View Patent ↗In one example of one aspect of the invention, a data storage cartridge is provided. The data storage cartridge includes a housing having at least one opening, a reel rotatably disposed within the housing and accessible through the opening, the reel capable of translating axially, a biasing member for biasing the reel toward the opening, and an absorbing member disposed between the reel and a portion of the housing opposite the opening. In one example, the absorbing member includes a spring constant value of greater than 30 ounces per inch. The absorbing member may be disposed to engage and dampen the motion of the reel when the reel is displaced beyond a desired distance.
1. A storage media cartridge, comprising:
a housing having an opening;
a reel rotatably disposed within the housing and accessible through the opening, the reel capable of translating axially;
a biasing member for biasing the reel axially toward the opening; and
an absorbing member disposed between the reel and a portion of the housing opposite the opening, wherein the absorbing member is positioned to dampen movement of the reel, wherein the absorbing member has a spring constant value greater than 30 ounces per inch.
2. The storage media cartridge of claim 1 , wherein the absorbing member has a spring constant value greater than 50 ounces per inch.
3. The storage media cartridge of claim 1 , wherein the absorbing member has a spring constant greater than the biasing member.
4. The storage media cartridge of claim 1 , wherein the absorbing member comprises a foam rubber material.
5. The storage media cartridge of claim 1 , wherein the absorbing member is spatially fixed with respect to the cartridge housing.
6. The storage media cartridge of claim 1 , wherein the absorbing member is disposed on a portion of an interior surface of the cartridge housing and at least partially aligned axially with a hub portion and flange portion of the reel.
7. The storage media cartridge of claim 1 , wherein the absorbing member is spatially fixed with respect to the reel.
8. The storage media cartridge of claim 1 , wherein the housing includes a cylindrical protrusion on the inside of the housing and the absorbing member is positioned at least partially within the cylindrical protrusion.
9. The storage media cartridge of claim 1 , wherein the biasing member and the absorbing member are coaxially aligned with the reel.
10. The storage media cartridge of claim 1 , wherein the biasing member straddles at least a portion of the absorbing member.
11. A storage media cartridge, comprising:
a housing having an opening;
a reel rotatably disposed within the housing and accessible through the opening, the reel capable of translating axially; and
an absorbing member coaxially aligned with the reel and disposed between the reel and a portion of the housing for dampening movement of the reel, wherein the absorbing member has a spring constant value greater than 30 ounces per inch.
12. The storage media cartridge of claim 10 , further comprising a biasing member biasing the reel toward an opening within the housing.
13. The storage media cartridge of claim 10 , wherein the absorbing member has a spring constant value greater than 50 ounces per inch.
14. The storage media cartridge of claim 10 , wherein the absorbing member comprises a foam rubber material.
15. The storage media cartridge of claim 10 , wherein the absorbing member is spatially fixed with respect to the cartridge housing.
16. The storage media cartridge of claim 10 , wherein the absorbing member is spatially fixed with respect to the reel.
17. The storage media cartridge of claim 10 , wherein the housing includes a cylindrical protrusion on the inside of the housing and the absorbing member is positioned at least partially within the cylindrical protrusion.
18. A method for disposing a reel within a cartridge housing, comprising,
rotatably mounting a reel within a cartridge housing, the reel capable of translating axially; and
disposing an absorbing member between the reel and a portion of the cartridge housing, wherein the absorbing member has a spring constant value greater than 30 ounces per inch.
19. The method of claim 18 , wherein the reel and the absorbing member are coaxially aligned.
20. The method of claim 18 , further including disposing a biasing member for biasing the reel toward an opening within the housing.
21. The method of claim 18 , wherein the absorbing member has a spring constant value greater than 50 ounces per inch.
22. The method of claim 18 , wherein the absorbing member comprises a foam rubber material.
23. The method of claim 18 , wherein the absorbing member is spatially fixed with respect to the cartridge housing.
24. The method of claim 18 , wherein the absorbing member is spatially fixed with respect to the reel.
25. The method of claim 18 , wherein the housing includes a cylindrical protrusion on the inside of the housing and the absorbing member is positioned at least partially within the cylindrical protrusion.
