Abstract

A tape cartridge for a magnetic tape may be provided. The tape cartridge includes a magnetic tape surrounded by a housing and a temperature indicator that signals a temperature of the tape cartridge, for example, by a thermochromic label. Additionally, a system for tape cartridge data protection that interoperates with the tape cartridge is provided. The system includes a storage for holding a tape cartridge, a sensor that detects temperature information from the temperature indicator of the tape cartridge, and a control unit for controlling an actuator that performs an action depending on the detected temperature information. Furthermore, a method for operating the system for tape cartridge data protection is proposed.

First claim

What is claimed is:

1. A tape cartridge for a magnetic tape, the tape cartridge comprising:
a magnetic tape surrounded by a housing; and
a temperature indicator that signals a temperature of the tape cartridge, wherein the temperature indicator is a temperature sensitive sticker attached to the tape cartridge, wherein the temperature sensitive sticker changes color depending on the temperature, and wherein the temperature sensitive sticker depicts different barcodes depending on the temperature.

2. The tape cartridge according to claim 1 , wherein the temperature indicator signals two statuses relating to at least two temperature ranges.

3. The tape cartridge according to claim 1 , wherein the temperature indicator signals three temperature ranges.

4. The tape cartridge according to claim 1 , wherein the tape cartridge is of type Linear Tape-Open (LTO).

5. The tape cartridge according to claim 1 , further comprising:
a humidity sticker that signals humidity information.

6. A system for tape cartridge data protection that interoperates with a tape cartridge, the tape cartridge comprising a magnetic tape surrounded by a housing and a temperature indicator that signals a temperature of the tape cartridge, the system comprising:
a storage for holding a tape cartridge;
a sensor that detects temperature information from the temperature indicator of the tape cartridge;
a climate chamber; and
a control unit for controlling an actuator that performs an action depending on the detected temperature information, wherein the actuator moves the tape cartridge into the climate chamber if the detected temperature is outside a predefined temperature range.

7. The system according to claim 6 , wherein the sensor is a camera and a barcode reader.

8. The system according to claim 6 , wherein the storage is a component of a tape library.

9. The system according to claim 6 , wherein the sensor is integrated into a gripper of a tape library.

10. The system according to claim 6 , wherein the sensor further detects humidity information from a humidity sticker attached to the cartridge; and wherein the control unit further performs the action depending on a combination of the detected temperature information and the detected humidity information.

11. A method for operating a system for tape cartridge data protection, the system interoperates with a tape cartridge, the tape cartridge comprising a magnetic tape surrounded by a housing and a temperature indicator for signaling a temperature of the tape cartridge, the system comprising:
a storage for holding a tape cartridge;
a sensor that detects temperature information from the temperature indicator of the tape cartridge;
a control unit of an actuator that performs an action depending on the detected temperature information; and
wherein the method comprises:
selecting a cartridge by the actuator controlled by the control unit;
detecting a temperature of the cartridge by the sensor;
upon the temperature being in a predefined temperature range, moving the tape cartridge into a tape drive; and
upon the temperature being outside the predefined temperature range, moving the cartridge into a climate chamber.

12. The method according to claim 11 , wherein the tape drive and the climate chamber are part of a tape library.

13. The method according to claim 11 , further comprising:
determining whether the detected temperature is below or above the predefined temperature range.

14. The method according to claim 11 , further comprising:
upon receiving an urgency signal, interrupting the moving the cartridge into a climate chamber, and moving the cartridge directly into the tape drive.

15. The method according to claim 11 , further comprising:
determining, after an adaptable delay, whether the temperature of the tape cartridge in the climate chamber is still outside the predefined temperature range.

16. The method according to claim 11 , wherein the sensor further detects humidity information from a humidity sticker attached to the cartridge; and wherein the control unit further performs the action depending on a combination of the detected temperature information and the detected humidity information.
