Abstract

Claims (55)

1. An archival cartridge management system for conditioning removable data cartridges and normal archival operations, comprising:

a plurality of cartridge holders configured to be coupled to a plurality of removable data cartridges, wherein:

the plurality of cartridge holders comprise a cartridge holder,

the plurality of removable data cartridges comprises a removable data cartridge, and

the cartridge holder comprises a connector, wherein the connector is configured for coupling with the removable data cartridge;

a controller coupled to the plurality of connectors, wherein:

the controller performs archival functions on the plurality of removable data cartridges,

the controller reads from the plurality of removable data cartridges to determine if at least some data stored on the removable data cartridge should be refreshed, and

the controller refreshes data stored on the removable data cartridge based, at least in part, on the determination.

2. The archival cartridge management system for conditioning removable data cartridges and normal archival operations as recited in claim 1 , wherein the archival cartridge management system can monitor the data integrity of the removable data cartridge.

3. The archival cartridge management system for conditioning removable data cartridges and normal archival operations as recited in claim 1 , wherein the archival cartridge management system is adapted to use removable data cartridges that include a hard disk drive.

4. The archival cartridge management system for conditioning removable data cartridges and normal archival operations as recited in claim 1 , wherein the archival cartridge management system can automatically refresh data stored on the removable data cartridge when the data is determined prone to errors.

5. The archival cartridge management system for conditioning removable data cartridges and normal archival operations as recited in claim 1 , wherein the connector electrically communicates between the removable data cartridge and the controller.

6. The archival cartridge management system for conditioning removable data cartridges and normal archival operations as recited in claim 1 , wherein the controller automatically performs its functions on the removable data cartridge.

7. The archival cartridge management system for conditioning removable data cartridges and normal archival operations as recited in claim 1 , further comprising a battery pack to supply power to the archival cartridge management system.

8. The archival cartridge management system for conditioning removable data cartridges and normal archival operations as recited in claim 1 , further comprising a battery pack to supply power to the archival cartridge management system, wherein the battery pack is coupled to the connector.

9. The archival cartridge management system for conditioning removable data cartridges and normal archival operations as recited in claim 1 , wherein:

the removable data cartridge comprises a hard disk drive, and

the hard disk drive includes an error correction circuit.

10. The archival cartridge management system for conditioning removable data cartridges and normal archival operations as recited in claim 1 , further comprising a cartridge database, wherein:

the cartridge database stores information on the plurality of removable data cartridges, and

the cartridge database can be used to determine when the removable data cartridge should be refreshed.

11. A method for conditioning removable data cartridges and normal archival operations performed with a cartridge holder, the method comprising steps of:

accepting insertion of the removable data cartridge;

performing archival functions on removable data cartridges;

reading information from removable data cartridges;

automatically determining if at least some data stored on a removable data cartridge should be refreshed, wherein the determining step is performed outside the removable data cartridge; and

refreshing data stored on the removable data cartridge based, at least in part, on the automatically determining step, wherein the performing and refreshing steps are performed with the cartridge holder.

12. The method for conditioning removable data cartridges and normal archival operations performed with the cartridge holder as recited in claim 11 , wherein the information is stored in an archival sense field.

13. The method for conditioning removable data cartridges and normal archival operations performed with the cartridge holder as recited in claim 11 , further comprising a step of maintaining an archival sense field, which is indicative of when data should be refreshed.

14. The method for conditioning removable data cartridges and normal archival operations performed with the cartridge holder as recited in claim 11 , wherein the determining step comprises steps of:

reading data from the removable data cartridge; and

determining that data is in peril of being lost.

15. The method for conditioning removable data cartridges and normal archival operations performed with the cartridge holder as recited in claim 11 , wherein the determining step comprises steps of:

analyzing the information; and

determining that data is in peril of being lost.

16. The method for conditioning removable data cartridges and normal archival operations performed with the cartridge holder as recited in claim 11 , wherein the removable data cartridge comprises a hard drive.

17. The method for conditioning removable data cartridges and normal archival operations performed with the cartridge holder as recited in claim 11 , further comprising a step of performing a media refresh operation that reads and re-writes data to the removable data cartridge.

18. A method for conditioning removable data cartridges and normal archival operations performed with a cartridge holder, the method comprising steps of:

accepting insertion of the removable data cartridge;

writing information to removable data cartridges with the cartridge holder;

reading information from removable data cartridges with the cartridge holder;

automatically determining if at least some data stored on a removable data cartridge is prone to errors, wherein the automatically determining step is performed outside the removable data cartridge; and

refreshing data stored on the removable data cartridge with the cartridge holder based, at least in part, on the determining step.

19. The method for conditioning removable data cartridges and normal archival operations performed with the cartridge holder as recited in claim 18 , further comprising a step of reading an archival sense field from the removable data cartridge.

20. The method for conditioning removable data cartridges and normal archival operations performed with the cartridge holder as recited in claim 18 , further comprising a step of maintaining an archival sense field, which is indicative of when data should be refreshed.

21. The method for conditioning removable data cartridges and normal archival operations performed with the cartridge holder as recited in claim 18 , wherein the determining step comprises steps of:

reading data from the removable data cartridge; and

determining that data is in peril of being lost.

22. The method for conditioning removable data cartridges and normal archival operations performed with the cartridge holder as recited in claim 18 , wherein the determining step comprises steps of:

analyzing the information; and

determining that data is in peril of being lost.

23. The method for conditioning removable data cartridges and normal archival operations performed with the cartridge holder as recited in claim 18 , wherein the refreshing step is performed autonomously by the removable data cartridge.

24. The method for conditioning removable data cartridges and normal archival operations performed with the cartridge holder as recited in claim 18 , wherein the cartridge holder accepts a plurality of removable data cartridges simultaneously.

25. The method for conditioning removable data cartridges and normal archival operations performed with the cartridge holder as recited in claim 18 , wherein the removable data cartridge comprises at least one of a hard drive and a solid state drive.
