Tape cartridge paired data

Abstract

A method for maintaining paired data between tape cartridges and linking the paired data to through medium auxiliary memory devices is presented. One method includes providing a first tape cartridge possessing a first medium auxiliary memory device and a first tape medium and a second tape cartridge possessing a second medium auxiliary memory device and a second tape medium. Data maintained on the first tape medium can be copied to the second tape medium. A first record can be stored on the first medium auxiliary memory device indicating that data on the first tape medium was copied to the second tape medium. Likewise, a second record can be stored on the second medium auxiliary memory device indicating that data on the second tape medium originated from the first tape medium.
