Preventive Maintenance Handling and Storing Cartridge Tapes
Do not remove the leader block, pull out the tape, or press the reel lock. If the
leader block is detached from the tape, contact the tape supplier for a leader block
repair kit.
When transporting cartridge tapes, do not stack the cartridges more than six high.
Pack them carefully with the reel sides upright. The leader block edges can crack if
they engage with each other.
To store or transport tape cartridges in an ACL cartridge magazine, follow the
same guidelines as you would for storing or transporting individual cartridge tapes.
