LTO Cartridge Memory
Linear Tape Open—Cartridge Memory (LTO-CM) is EEPROM memory that is
embedded in every Ultrium tape cartridge. It is non-volatile and is contactless
in that it is read by inductive coupling rather than electrical contact.
The Cartridge Memory is used to store the tape directory and diagnostic and
log information. Because of the speed at which it can be read, load and
unload times are reduced, information is found on the tape more quickly and
fewer tape passes are needed, increasing tape reliability.
The memory is primarily designed to speed up internal operations in the
drive, but it also contains free space that can be used by application software.
Of the 4 kilobyte memory, about 1 kilobyte is free space. This may be used to
store “common” information (shared by all software vendors) and “vendor-
unique” information (specific to the application).
A SCSI access method has been defined to allow hosts to use this free space
using Write Attribute and Read Attribute commands. For information on these
commands, see Chapter 4 of The SCSI Interface, Volume 3 of this HP Ultrium
Technical Reference Manual.
For details of use of LTO-CM in library applications, see “Using Cartridge
Memory (LTO-CM)” on page 47.
For more information on LTO-CM, see “LTO Cartridge Memory” in Chapter 5
of Background Information, Volume 6 of this HP Ultrium Technical Reference
Manual.
