ABSTRACT:
A magnetic tape cartridge, such as a Linear Tape Open cartridge, stores parameters in a non-volatile memory, such as a Media Auxiliary Memory page of a Cartridge Memory, for use in reading and writing to a magnetic tape. A backup copy of the parameters is made in the non-volatile memory for use in reading and writing to the magnetic tape in the event that the primary copy of the parameters becomes corrupt. If a tape drive fails to retrieve the primary copy of the parameters, the tape drive looks for the backup copy at a predetermined memory location, such as location 200h in the Cartridge Memory.
