1. A cartridge data storage system with information-theoretic security comprising:
a first cartridge storing a first encrypted data packet;
a second cartridge storing a second encrypted data packet; and
a shared controller providing read and write access to the first cartridge and the second cartridge, the shared controller having data partitioning circuitry including:
a file partitioner to divide a file into a first part and a second part;
a key generator to randomly generate one or more keys; and
a packet generator to combine the first part of the file with a linear combination of one or more of the keys to generate the first encrypted data packet, the packet generator further to combine the second part of the file with another linear combination of one or more of the keys to generate the second encrypted data packet.
