IBM 200 GB LTO-2 User Manual page 24

The IBM LTO-2 Ultrium 200 GB Data Cartridge includes a Linear Tape-Open
Cartridge Memory (LTO-CM) chip ( 1 in Figure 4 on page 13), that contains
information about the cartridge and the tape (such as the name of the
manufacturer that created the tape), as well as statistical information about the
cartridge's use. Whenever you unload a tape cartridge, the tape drive writes any
pertinent information to the cartridge memory. The storage capacity of the
LTO-CM is 4096 bytes.
The cartridge door 2 protects the tape from contamination when the cartridge is
out of the drive. Behind the door, the tape is attached to a leader pin 3 . When
you insert the cartridge into the drive, a threading mechanism pulls the pin (and
tape) out of the cartridge, across the drive head, and onto a non-removable takeup
reel. The head can then read or write data from or to the tape.
The write-protect switch 4 prevents data from being written to the tape
cartridge. The label area 5 provides a location for you to place a label. Affix only
a bar code label. When affixing a label, place it only in the recessed label area. A
label that extends outside of the recessed area can cause loading problems in the
drive. The insertion guide 6 is a large, notched area that prevents you from
inserting the cartridge incorrectly.
The IBM LTO-2 Ultrium 200 GB Data Cartridge has a nominal cartridge life of 5000
load and unload cycles. The Generation 2 cartridge is purple; the Generation 1
cartridge is black.
