3 The library sends an ACI Unload command to eject the cartridge.
4 The drive ejects the tape to Eject Point.
5 The picker takes the cartridge from drive and places it in its storage slot.
6 Load Forces
7 The unload force is 4.45N maximum. The peak load force varies
according to the speed at which the cartridge is inserted into the drive.
The peak load force occurs when the cartridge begins to accelerate the
drive carrier and only lasts for a short time. The following graph plots two
examples of peak load force against load speed:
Using Cartridge Memory (LTO-CM)
See “Use the following table to resolve cleaning problems:” on page 26 for
troubleshooting suggestions.
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
