1. A data processing method comprising:
- reading, by a computer processor, a removable recording medium containing management data set at an access position, the management data linking a globally unique identifier and an access path together, the globally unique identifier uniquely identifying a material data and the access path indicating the path on the removable recording medium to the material data;
notifying, by a computer processor, a remote network location that the removable recording medium is set at the access position when it is determined that the management data has linked the globally unique identifier with the access path;
accessing the removable recording medium at the access position; and
providing said access path in response to a request designating said globally unique identifier from the remote network location.

5. A data processing method executed by a computer based on an application program, a management program, and a file system program, comprising:
-
reading, by a computer processor, a removable recording medium containing management data set at an access position, the management data linking a globally unique identifier and an access path together, the globally unique identifier uniquely identifying a given material data in the removable recording medium; notifying, by a computer processor, a remote network location that the removable recording medium is set at the access position when it is determined that the management data has linked the globally unique identifier with the access path; accessing the removable recording medium at the access position; issuing a request designating said globally unique identifier, by said application program at the remote network location to said management program; providing said access path, to said file system program, in response to said request, said access path corresponding to said designated globally unique identifier contained in said management data; and accessing, by the file system, said material data stored at a physical address of said removable recording medium, based on said access path. - View Dependent Claims (6)

7. A non-transitory computer-readable memory including program code stored thereon, the program code being executable to perform operations comprising:
-
reading a removable recording medium containing management data set at an access position, the management data linking a globally unique identifier and an access path together, the globally unique identifier uniquely identifying a given material data and the access path indicating the path to the given material data in the removable recording medium; notifying a remote network location that the removable recording medium is set at the access position when it is determined that the management data has linked the globally unique identifier with the access path; accessing the removable recording medium at the access position; and providing said access path in response to a request, from the remote network location, designating said globally unique identifier. - View Dependent Claims (8)

9. A data management hardware apparatus comprising:
-
a reading means that reads a removable recording medium containing management data set at an access position, the management data linking a globally unique identifier and an access path together, the globally unique identifier uniquely identifying a given material data and the access path indicating the path to the given material data in the removable recording medium; a notifying means that notifies a remote network location that the removable recording medium is set at the access position when it is determined that the management data has linked the globally unique identifier with the access path; an accessing means that accesses the removable recording medium at the access position; and a providing means that provides said access path in response to the request, from the remote network location, designating said globally unique identifier. - View Dependent Claims (10)
