Abstract

Described are embodiments of an invention for a textured interface between a notch of a data storage cartridge and a retention tab of a storage cell. The textured surface reduces the contact surface between the retention tab and the notch of the data storage cartridge. The reduced contact surface between the retention tab and notch of the data storage cartridge reduces the amount of friction between the retention tab and the notch of the data storage cartridge. The data storage cartridge can thus be removed from the storage cell with less force than that required by the prior art having a generally smooth interface between the notch of the data storage cartridge and the retention tab of the storage cell.

Claims

1. A data storage cartridge comprising:

a cartridge housing having a notch on at least one side, said notch engaging with a retention tab that protrudes from a side wall of a storage cell for retaining said data storage cartridge within said storage cell when said data storage cartridge is inserted into said storage cell; and

said notch having at least one textured surface configured to reduce a force necessary for inserting and/or removing said data storage cartridge from said storage cell.

2. The data storage cartridge of claim 1, wherein said cartridge housing comprises a top, bottom, front, back and two sides.

3. The data storage cartridge of claim 1, wherein said at least one textured surface of said notch is configured to contact said retention tab when said data storage cartridge is inserted into said storage cell.

4. The data storage cartridge of claim 1, wherein said at least one textured surface comprises at least one of bumps, lines, grooves.

5. The data storage cartridge of claim 1, wherein a texture of said at least one textured surface of said notch is configured to reduce a contact surface between said notch and said retention tab.

6. The data storage cartridge of claim 1, wherein said data storage cartridge is a tape cartridge.

7. The data storage cartridge of claim 1, wherein said at least one textured surface of said notch is configured to reduce the force necessary for inserting and/or removing said data storage cartridge from said storage cell compared to a force necessary for inserting and/or removing a data storage cartridge having a notch with a non-textured surface from said storage cell.

8. The data storage cartridge of claim 4, wherein said textured surface of said retention tab reduces a contact surface between said notch and said retention tab.

9. The data storage cartridge of claim 5, wherein said at least one textured surface of said notch reduces a contact surface between said notch and said retention tab.

10. A data storage cartridge, comprising

a cartridge housing having a notch on at least one side, said notch engaging with a retention tab that protrudes from a side wall of a storage cell for retaining said data storage cartridge within said storage cell when said data storage cartridge is inserted into said storage cell;

and

said notch having at least one textured surface,

wherein said texture of said notch reduces a contact surface between said notch and said retention tab,

wherein said reduced contact surface between said notch and said retention tab reduces an amount of force necessary for removing said data storage cartridge from said storage cell.

11. A data storage cartridge comprising:

a cartridge housing comprising a top, bottom, front, back and two sides;

a notch on at least one side of said data storage cartridge for retaining said data storage cartridge within a storage cell having a pair of opposing side walls, a back wall, a floor and an opening for inserting and removing said data storage cartridge;

said notch being configured to engage with a retention tab protruding from a side wall of said storage cell when said data storage cartridge is inserted into said storage cell; and

wherein said notch has at least one textured surface that contacts said retention tab when said data storage cartridge is inserted into said storage cell, said at least one textured surface being configured to reduce a force necessary for inserting and/or removing said data storage cartridge from said storage cell.

12. The data storage cartridge of claim 11, wherein said at least one textured surface comprises at least one of bumps, lines, grooves.

13. The data storage cartridge of claim 11, wherein a texture of at least one textured surface of said notch is configured to reduce a contact surface between said notch and said retention tab.

14. The data storage cartridge of claim 13, wherein said reduced contact surface between said notch and said retention tab reduces an amount of force necessary for removing said data storage cartridge from said storage cell.

15. The data storage cartridge of claim 11, wherein said at least one textured surface of said notch is configured to reduce the force necessary for inserting and/or removing said data storage cartridge from said storage cell compared to a force necessary for inserting and/or removing a data storage cartridge having a notch with a non-textured surface from said storage cell.
