Abstract

Method, system, and computer program product embodiments for recording data on a contactless integrated circuit (IC) memory associated with a data storage cartridge are provided. In one exemplary embodiment, a consistency is verified between a TOC written to a contactless IC memory and an index, wherein if the TOC and the index are inconsistent, a TOC profile file is refreshed with data from the index. The TOC is written to the contactless IC memory.

First claim

What is claimed is:

1. A method for recording data on a contactless integrated circuit (IC) memory associated with a data storage cartridge, comprising:
verifying consistency between a TOC (table of contents) written to a contactless IC memory and an index, wherein if the TOC and the index are inconsistent, a TOC profile file is refreshed with data from the index, and
writing the TOC to the contactless IC memory.

2. The method of claim 1 , further including parsing the index of a plurality of files to be recorded on the storage media of the data storage cartridge with the table of contents (TOC) profile file to build the table of contents (TOC) specific to an owning application of the plurality of files.

3. The method of claim 1 , further including storing the index on the storage media of the data storage cartridge.

4. The method of claim 1 , further including storing the TOC profile file on the storage media of the data storage cartridge.

5. The method of claim 1 , further including, previous to verifying consistency between the TOC written to the contactless IC memory and the index:
building an additional TOC by reading the index and the TOC profile file from the storage media, and
comparing the additional TOC with at least one of the TOC written to the contactless IC memory and the index to verify additional consistency.

6. The method of claim 1 , wherein writing the TOC to the contactless IC memory includes sending the TOC to a radio frequency (RF) communication unit for transmission to the contactless IC memory.

7. A system for recording data file information describing contents of storage media of a data storage cartridge in an automated storage and retrieval library, comprising:
a processor device operational in the automated storage and retrieval library, the processing device adapted for verifying consistency between a table of contents (TOC) written to a contactless IC memory and an index, wherein if the TOC and the index are inconsistent, a TOC profile file is refreshed with data from the index, and
a contactless integrated circuit (IC) memory in communication with the processor device and embedded in the data storage cartridge, the contactless IC memory adapted for storing the table of contents (TOC).

8. The system of claim 7 , wherein the processor device is further adapted for building the table of contents (TOC) specific to an owning application of a plurality of files to be recorded on the storage media by parsing the index of the plurality of files with the table of contents (TOC) profile file.

9. The system of claim 7 , wherein the processor device is further adapted for storing the index on the storage media of the data storage cartridge.

10. The system of claim 7 , wherein the processor device is further adapted for storing the TOC profile file on the storage media of the data storage cartridge.

11. The system of claim 7 , wherein the processor device is further adapted for, previous to verifying consistency between the TOC written to the contactless IC memory and the index:
building an additional TOC by reading the index and the TOC profile file from the storage media, and
comparing the additional TOC with at least one of the TOC written to the contactless IC memory and the index to verify additional consistency.

12. The system of claim 7 , wherein the processor device is further adapted for, pursuant to writing the TOC to the contactless IC memory, sending the TOC to a radio frequency (RF) communication unit for transmission to the contactless IC memory.

13. The system of claim 7 , wherein the storage media is compatible with a Linear Tape Open-5 (LTO-5) data storage format.

14. The system of claim 7 , wherein the automated data storage and retrieval system includes an automated tape library, and the data storage cartridge includes a tape cartridge device for insertion in to the automated tape library.

15. A computer program product for recording data on a contactless integrated circuit (IC) memory associated with a data storage cartridge, the computer program product comprising a non-transitory computer-readable storage medium having computer-readable program code portions stored therein, the computer-readable program code portions comprising:
a first executable portion for verifying consistency between a TOC written to a contactless IC memory and an index, wherein if the TOC and the index are inconsistent, a TOC profile file is refreshed with data from the index; and
a second executable portion for writing the TOC to the contactless IC memory.

16. The computer program product of claim 15 , further including a third executable portion for parsing the index of a plurality of files to be recorded on the storage media of the data storage cartridge with the table of contents (TOC) profile file to build the table of contents (TOC) specific to an owning application of the plurality of files.

17. The computer program product of claim 15 , further including a third executable portion for storing the index on the storage media of the data storage cartridge.

18. The computer program product of claim 15 , further including a third executable portion for storing the TOC profile file on the storage media of the data storage cartridge.

19. The computer program product of claim 15 , further including a fourth executable portion for, previous to verifying consistency between the TOC written to the contactless IC memory and the index:
building an additional TOC by reading the index and the TOC profile file from the storage media, and
comparing the additional TOC with at least one of the TOC written to the contactless IC memory and the index to verify additional consistency.

20. The computer program product of claim 15 , further including a third executable portion for, pursuant to writing the TOC to the contactless IC memory, sending the TOC to a radio frequency (RF) communication unit for transmission to the contactless IC memory.
