IBM 3590 - Manual (Page 108)

v Do not load a damaged cartridge into a tape subsystem. During an
emergency, if you need to recover data from a damaged cartridge, call your
service representative. (IBM charges the customer for the time and materials
that are used during the service call.)
See Figure 21 to identify the parts of a cartridge that may become damaged.
The following lists the parts of the tape cartridge:
1 Cartridge Case
2 Leader Block Latch
3 Leader Block
4 Cartridge Tape
5 File-Protect Selector (shows either a closed lock or a dot)
Examples of cartridge damage are included in the following list.
v The cartridge case (see item
1 ) is cracked, broken, or contains liquid.
v The leader block latch (see item 2 ) is broken.
v The leader block (see item 3 ) is broken.
v The tape (see item 4 ) has detached from the leader block (see item 3 ).
– See “Leader Block Replacement” on page 90.
– If the leader block is damaged, or not properly attached to the tape, a
load error may occur. This happens when the drive tries to load or
unload the cartridge.
