Life management method of storage medium, storage device, storage system and storage medium

摘要

The present invention relates to a method of managing a life of a storage medium for detecting the service life of a storage medium (1), a storage device and a storage system. The medium life management information (14) shown in the read / write state of the medium is recorded in the storage medium (1). The drive (5) reads the medium life management information (14) from the storage medium (1) at the time of loading of the storage medium (1) and updates the medium life management information (14) in accordance with at least one of the read / write operations of the storage medium (1). When the storage medium 1 is unloaded, the medium life management information 14 is written into the storage medium 1. The medium life management information (14) is used to determine the medium life of the drive (5) or the host (4). Since the management information corresponding to the actual read / write state is detected, deterioration of the storage medium can be accurately detected.
