LTO-Cartridge Memory (EEPROM)

LTO Cartridge Memory (LTO-CM) is EEPROM 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.
Interface specification
Contactless, passive RF interface using a proximity inductive coupling with a range in the order
•
of millimeters.
• Power to the transponder is coupled through the interface.
• The range depends on implementation (maximum 10 to 20 mm). The best error rate
performance occurs at short distances.
