Abstract

Embodiments of methods and systems for controlling access to information stored on memory or data storage devices are disclosed. In various embodiments, methods of retrieving information from a data storage device previously deactivated by modification or degradation of at least a portion of the data storage device are disclosed.

Claims

1. A method of configuring a memory device comprising:

providing a memory device including a first data storage region including a material that is modifiable by a limited expected lifetime of data from the first data storage region and a second data storage region including a material that is substantially unmodifiable by a limited number of readings of data from the second data storage region;

storing primary read-support information in the first data storage region that is readable prior to modification of the material by a first data read system;

storing data of interest in the second data storage region that is ordered, encoded, encrypted, or otherwise structured so that it is readable with use of the primary read-support information;

providing secondary read-support information on the memory device that is readable by a second data read system, but not the first data read system, for decoding the ordered, encoded, encrypted, or otherwise structured data of interest.

2. The method of claim 1, including providing read-support information on the memory device that is readable by a second data read system but not the first data read system by storing secondary read-support information in the second data storage region.

3. The method of claim 2, including storing secondary read-support information at one or more locations in the second data storage region, wherein information about the one or more locations is available to the second data read system but not the first data read system.

4. The method of claim 1, wherein the primary read-support information includes index information.

5. The method of claim 1, wherein the primary read-support information includes an encryption key.

6. The method of claim 5, wherein the encryption key is a private key.

7. The method of claim 5, wherein the encryption key is a public key.

8. The method of claim 1, including storing data of interest in an optical data storage medium.

9. The method of claim 1, including storing data of interest in a magnetic data storage medium.

10. The method of claim 1, including providing read-support information on the memory device that is readable by an optical data read device.

11. The method of claim 1, including providing read-support information on the memory device that is readable by a magnetic data read device.

12. The method of claim 1, including providing secondary read-support information on the memory device in the form of at least one RFID.

13. The method of claim 1, including providing secondary read-support information on the memory device in the form of at least one resonant circuit.
