Abstract

A method for enabling different modes on a multi-modal data storage system such as a tape-based data storage system includes enabling a data storage system to operate in at least one of two modes, a first of the modes being different than a second of the modes. In one embodiment, the data storage system has all physical components required to operate in the first and second modes. An ability to operate in at least one of the modes is not allowed prior to enabling the data storage system to operate in the at least one of the modes.

Claims

1. A method for on-demand enablement of functionality of a multi-modal data storage system, the method comprising:

allowing a data storage system to read and/or write to a storage medium in a first data format but not a second data format, wherein the way data is written in the first data format is different than the way the same data is written in the second data format;

allowing the data storage system to operate in the second data format upon occurrence of a first condition;

upon occurrence of a second condition, no longer allowing the data storage system to operate in the second data format; and

charging a sum of money for enabling the data storage system to operate in the second data format.

2. The method as recited in claim 1, wherein each data format relates to compatibility with a data storage medium.

3. The method as recited in claim 1, wherein the first condition is purchase of computer instructions.

4. The method as recited in claim 3, wherein the computer instructions are selected from a group consisting of firmware, software, and a key.

5. The method as recited in claim 1, wherein the second condition is expiration of a prespecified time period.

6. The method as recited in claim 1, wherein the second condition is receipt of an instruction from a user of the data storage system.

7. The method as recited in claim 1, wherein the data storage system is a tape-based data storage system.

8. The method as recited in claim 1, wherein the storage medium is a magnetic storage medium.

9. A multi-modal data storage system, comprising:

a processor for enabling a data storage system to operate in a first of at least two modes, the first of the modes being different than a second of the modes, wherein the first mode includes operation in a first format and the second mode includes operation in a second format, and

wherein the data storage system is allowed to operate in the second of the modes only upon at least one of installation of additional computer instructions and receiving a key.

10. The multi-modal data storage system as recited in claim 9, wherein the multi-modal data storage system is a tape-based system.

11. The multi-modal data storage system as recited in claim 9, wherein a way data is written and/or read in the first format is different than the way the same data is written and/or read in the second format.

12. The multi-modal data storage system as recited in claim 9, wherein each data format relates to compatibility with a data storage medium.

13. The multi-modal data storage system as recited in claim 9, further comprising no longer allowing the data storage system to operate in the second data format upon occurrence of a second condition, wherein the second condition is at least one of expiration of a prespecified time period and receipt of an instruction from a user of the data storage system.

14. The multi-modal data storage system as recited in claim 9, wherein the multi-modal data storage system is a tape-based data storage system.

15. A computer program product for enabling different modes on a multi-modal data storage system, the computer program product comprising:

a computer readable storage medium having computer usable program code embodied therewith, the computer usable program code comprising;

computer usable program code configured to enable a data storage system to operate in a first of at least two modes, the first of the modes being different than a second of the modes, wherein the first mode includes operation in a first format and the second mode includes operation in a second format, and

computer usable program code configured to allow the data storage system to operate in the second of the modes only upon at least one of installation of additional computer instructions and receiving a key.

16. The computer program product as recited in claim 15, wherein the multi-modal data storage system is a tape-based system.

17. The computer program product as recited in claim 15, wherein a way data is written and/or read in the first format is different than the way the same data is written and/or read in the second format.

18. The computer program product as recited in claim 15, wherein each data format relates to compatibility with a data storage medium.

19. The computer program product as recited in claim 15, further comprising no longer allowing the data storage system to operate in the second data format upon occurrence of a second condition, wherein the second condition is at least one of expiration of a prespecified time period and receipt of an instruction from a user of the data storage system.

20. The computer program product as recited in claim 15, wherein the multi-modal data storage system is a tape-based data storage system.
