Attributes of data recorded on a magnetic tape are stored in an attribute information table saved in an MIC (Memory in Cassette) of a tape cassette accommodated in a tape streamer drive connected to a host computer. The attributes are recorded for every identifier used for identifying a recording unit of the data. For each identifier, the attributes include the name of a file, a title, a file creation date/time, a file updating date/time, the amount of data contained in the file, the type of the data and a compression rate of the data. The attributes include not only those supplied by the host computer but also attributes generated after a data recording operation as information on the recording location of data. The attributes generated after the data recording operation include a group number and an offset from the beginning of the group identified by the group number. For example, the present invention can be applied to the tape streamer drive.
