A data storage apparatus includes a first storing unit that stores data in a sequential-access recording medium, and that stores storage history information relating to the data stored. The sequential-access recording medium stores the data by sequential access, and a second storing unit that stores any one of specific data and data excluding the specific data, in the sequential-access recording medium. The second storing unit detects the specific data from among the data stored, based on the storage history information. |
