Claims13
A magnetic tape cartridge comprising:
- a magnetic tape;
- and
- a cartridge memory detachably attached to the magnetic tape cartridge for previously storing identification data that is externally, wirelessly read and written,
- wherein the identification data is readable from the cartridge memory attached to the magnetic tape cartridge to encipher information recorded on the magnetic tape with the identification data as key data and decipher the information from the magnetic tape with the key data, and
- wherein the magnetic tape cartridge and the cartridge memory hold first and second visual identifying indications indicative of a unique relation therebetween, respectively, to allow an operator to independently keep the magnetic tape and the detached cartridge memory and thereafter attach the cartridge memory again to the magnetic tape cartridge having the unique relation with the cartridge memory to decipher the information with the key data.
