Abstract

A media player is utilized to determine presence of defects in storage devices, and to retrieve replacement data from media management servers. The retrieval of the replacement data is performed during playback and/or use of the storage devices. The replacement data is only utilized during real time playback of the storage devices. The replacement data can also be stored within the data storage player, into the storage devices, and/or into external storage devices accessible during playback operations. Addressing information is created and/or modified to enable use of stored replacement data. A new copy of the data can be created in the same or in new storage device. The media management server performs access authentication operations during replacement data retrieval. The media management server is accessed via user-based webpage-like interfaces and/or dedicated APIs.

Claims

1. A method for data processing, the method comprising:

determining by a reader device, presence of defects in a magnetic medium, an optical medium or a magneto-optical medium of a storage device, wherein said defects prevent reading of at least a portion of data from the magnetic medium, an optical medium or a magneto-optical medium of said storage device;

communicating access information to a remote management server, wherein said communicated access information causes a user authentication operation and a copy verification operation to occur in said remote management server;

retrieving corresponding replacement data corresponding to said at least said portion of said data from said remote management server, based on success of said user authentication operation, including retrieving a new copy of said data stored in said storage device for storage and subsequent use and playback of said replacement data if the copy verification operation determines that said portion of data from said storage device exceeds a threshold;

identifying available and accessible portions the storage device; and

writing the replacement data in one or more identified available and accessible portions of the storage device.

2. The method according to claim 1, wherein said read data comprises multimedia information.

3. The method according to claim 1, wherein said storage device comprises a magnetic storage device, an optical storage device, a magneto-optical storage device, a magneto-electronic storage device, or a solid state storage device.

4. The method according to claim 1, comprising retrieving said replacement data from said remote management server during playback or use of said data.

5. The method according to claim 1, wherein said communicated access information causes said remote management server to enforce protection of applicable proprietary rights during said user authentication operation.

6. The method according to claim 1, comprising storing said retrieved replacement data to enable subsequent use or playback of said stored data by said storage device.

7. The method according to claim 1, further comprising adapting addressing information for accessing the one or more identified available and accessible portions of the magnetic medium, the optical medium or the magneto-optical medium which are not subject to defects which prevent reading and writing data at the available and accessible portions of the storage device during subsequent use or playback of said replacement data.

8. The method according to claim 1, further comprising disabling the portion of the data which the defects prevent reading.

9. The method according to claim 8, comprising disabling use of said storage device after said creation of said new copy of said stored data into a said storage device.

10. The method according to claim 1, wherein said remote management server performs user authentication to allow said retrieval of said replacement data.

11. The method according to claim 10, wherein said remote management server creates or updates personal user portfolios based on said user authentication.

12. The method according to claim 1, wherein said remote management server performs license verification to authenticate said stored data in said storage device.

13. A system for data processing, the system comprising:

one or more circuits for use in a reader device, said one or more circuits being operable to;

determine presence of defects in a magnetic medium, an optical medium or a magneto-optical medium of a storage device, wherein said defects prevent reading of at least a portion of data from the magnetic medium, an optical medium or a magneto-optical medium of said storage device;

communicate access information to a remote management server, wherein said communicated access information causes a user authentication operation and a copy verification operation to occur in said remote management server, the copy verification operation comparing a defective amount of said portion of data with a threshold;

retrieve replacement data corresponding to said at least said portion of said data from said remote management server, based on success of said user authentication operation;

retrieve from said remote management server a new copy of said data stored in said storage device for storage and subsequent use and playback of said replacement data if the copy verification operation determined that the defective amount of said portion of data from said storage device exceeds the threshold;

identify available and accessible portions of the magnetic medium, an optical medium or a magneto-optical medium which are not subject to defects which prevent reading and writing data at the available and accessible portions of the storage device where the replacement data may be written for subsequent use and playback of the replacement data; and

write the replacement data in one or more identified available and accessible portions of the storage device.

14. The system according to claim 13, wherein said read data comprises multimedia information.

15. The system according to claim 13, wherein said one or more circuits are operable to retrieve said replacement data from said remote management server during playback or use of said data.

16. The system according to claim 13, wherein said communicated access information causes said remote management server to enforce copyright protection for said at least a portion of data during said user authentication operation.

17. The system according to claim 13, wherein said one or more circuits are operable to store said retrieved replacement data to enable subsequent use or playback of said stored data by said storage device.

18. The system according to claim 17, wherein said one or more circuits are further configured to create or modify addressing information for accessing the one or more identified available and accessible portions of the magnetic medium, the optical medium or the magneto-optical medium which are not subject to defects which prevent reading and writing data at the available and accessible portions of the storage device during subsequent use or playback of said replacement data.

19. The system according to claim 13, wherein said one or more circuits are operable to disable the portion of data and replace defective data with the retrieved new copy for subsequent use and playback of said retrieved new copy.

20. The system according to claim 19, wherein said one or more circuits are operable to disable use of said storage device after said creation of said new copy of said stored data into a new storage device.

21. The system according to claim 13, wherein said remote management server performs user authentication to allow said retrieval of said replacement data.

22. The system according to claim 21, wherein said remote management server creates or updates personal user portfolios based on said user authentication.

23. The system according to claim 13, wherein said remote management server performs license verification to authenticate said stored data in said storage device.
