Cartridge Memory (LTO-CM)
LTO Cartridge Memory (LTO-CM) is EEPROM memory that is embedded in every LTO Ultrium tape
cartridge. It is non-volatile and is contactless in that it is read by RF coupling rather than electrical
contact.
Further information
• For general information about LTO-CM, see “LTO Cartridge Memory” in Chapter 5, “Cartridges”
in Background to Ultrium Drives, Volume 6 of the Ultrium Technical Reference Manual.
• For suggestions of how to make use of cartridge memory in libraries, see “Using Cartridge
Memory” in “Using Special Features in Libraries”, Chapter 2 of the Hardware Integration Guide,
Volume 1 of the HP LTO Ultrium Technical Reference Manual.
Automation interface
The interface between the tape drive and the library will support both the open standard
Automation/Device Interface (ADI) and the proprietary Automation Control Interface (ACI). The tape
drive defaults to the ACI protocol and will only transition to ADI when the library initiates an ADT
login exchange.
NOTE: The same connector is used for both interfaces; for convenience, it is referred to as the ADI
Connector in this manual.
