Abstract
A tape cartridge is described including tape storage medium maintaining stored encrypted data that can be unencrypted via an encryption key. The tape cartridge also contains a medium auxiliary memory possessing a moniker wherein the moniker identifies the encryption key. The tape cartridge further includes a threshold parameter stored in the medium auxiliary memory wherein the threshold parameter influences a moniker state control, the moniker state control comprises an on state and an off state wherein the off state disables the moniker from identifying the encryption key.
