- 12. A storage system comprising:a storage device for accessing a loaded storage medium, and reading/writing data from/to said storage medium; and a managing device for managing said storage device; wherein said storage device reads medium life management information from said loaded storage medium, and thereafter, detects an operating state of at least one of the reading and the writing of data in said storage medium, updates said medium life management information according to results of such detection, and writes said updated medium life management information to said storage medium upon unloading the storage medium, and, in addition, reports information related to said medium life management information to said managing device in response to a request from said managing device, wherein said storage device detects a plurality of states of at least one of the reading and the writing of data in said storage medium, with the plurality of states being read/write characteristics of said storage medium, and updates said medium life management information according to each of said plurality of states, and wherein said storage device analyzes each of the plurality of states of said medium life management information, and determines the life of said storage medium based on the respective analysis results.
- 13. The storage system according to claim 12, wherein said storage device analyzes said medium life management information, determines the life of said storage medium, and reports said determination results to said managing device.
- 14. The storage system according to claim 12, wherein said storage device comprises a library device, said library device comprising:a storage drive for accessing a loaded storage medium, and for reading/writing data from/to said storage medium; and an accessor for loading a desired storage medium into said storage drive, and removing said storage medium from said storage drive.
- 15. A storage medium stored program for managing the life of a storage medium in a storage device, which accesses a loaded storage medium for reads/writes data from/to said storage medium, wherein said program comprises:a program for reading medium life management information from said loaded storage medium; a program for updating said medium life management information according to an operating state of at least one of the reading and the writing of said storage medium data, wherein said updating program detects a plurality of states of at least one of the reading and the writing of data in said storage medium, with the plurality of states being read/write characteristics of said storage medium, and updates said medium life management information according to each of said plurality of states; a program for writing said updated medium life management information to said storage medium upon unloading the storage medium; and a program for analyzing each of said plurality of states of medium life management information, and for determining the life of said storage medium based on the results of each analysis.
- 16. A storage device for accessing a loaded storage medium, and reading/writing data from/to said storage medium, comprising:read/write unit to read/write data from/to said storage medium; and control unit to control said read/write unit, wherein said control unit, develops medium life management information, which has been read from said loaded storage medium, to a memory, and thereafter, detects an operating state of at least one of the reading and the writing of data in said storage medium by said read/write unit, updates said medium life management information according to results of such detection, and writes said updated medium life management information to said storage medium upon unloading the storage medium, wherein said control unit detects a plurality of states of at least one of the reading and the writing of data in said storage medium, with the plurality of states being read/write characteristics of said storage medium, and updates said medium life management information according to each of said plurality of states, and wherein said control unit analyzes each of the plurality of states of said medium life management information, and determines the life of said storage medium based on the respective analysis results.
