Abstract
When a video cassette having a tag adhered thereto is mounted on the information processing apparatus or brought to a position within a predetermined distance therefrom, a read-writer reads a serial number from the tag and determines whether the read serial number has already been stored in a memory. If the determination has proved that the serial number has been stored in the memory, the read-writer reads current update history data from the tag and determines whether the read current update history data coincides with the update history data that has been stored in the memory. When it has been determined that the current update history data does not coincide with that stored in the memory, the read-writer reads whole data from the tag 2 and stores the read data in the memory, from which the data is read so as to be processed. In contrast, when it has been determined that the current update history data coincides with that stored in the memory, the read-writer reads whole data of the tag from the memory and processes the read data, instead of reading the data from the tag.
