Overview
The CM is a 4096 byte write/read device mounted in the cartridge. The interface to
external devices is via a contactless radio frequency system. The radio frequency
provides power transfer and write/read access.
The CM contains:
* LTO-CM manufacturing information
* LTO-CM page control information
* Cartridge initialization information
* Tape directory
* Cartridge information
o Manufacturer info
o Pass history
o Error history
o Usage
o Tape Alert flags
