Tape handling and storage
Most tapes are supplied in sealed cartridges. Tapes are provided this way so
that the tape will remain in a clean environment. Opening the cartridge
enables dirt and airborne particles to enter and contaminate the cartridge.
The cartridge must only be opened by the tape drive and not by an operator.
The tape is also held under proper tension inside the cartridge. If the cartridge
is dropped, this tension is relaxed. Inserting a dropped cartridge into a tape
drive can often cause a misload that results in a jam. The jam ruins the tape
and can cause physical damage if the cartridge is not removed properly.
When you store tapes, place them in their protective containers and store them
on their ends. Store the tapes in a clean, dry area at normal room temperature
and away from magnetic fields.
Environmental issues
The operating environment might adversely affect tape drive operation. The
tape drive is designed to operate in a clean environment.
When tape is installed in a tape drive, the clearance between the heads and the
tape is measured in microns. Even particles of smoke are larger than the space
available between the tape and the heads. Other environmental factors that
adversely affect tape drive operation are dirt, dust, fibers, and airborne
particles. Ensure that you operate in a clean environment.
Tape drive cleaning
Even if the operating environment is clean, dirt might build up on the heads of
any tape drive. Every time tape motion occurs, some of the media surface
comes off on the heads. Over time, this material builds up, causing the tape
head clearance to increase. The increased tape head clearance produces reading
and writing errors. Most tape drives today have a built-in cleaning indicator to
notify you when the tape needs cleaning.
Do not use any non-DLT cleaning cartridges with these tape drives. You can
use cleaning cartridges only for a limited number of times. A cleaning cartridge
is expired after it has been used for the maximum number of times as
indicated.
When a cleaning cartridge is expired, you must replace it. Never reuse an
expired cleaning cartridge. If you continue to use an expired cleaning cartridge,
it reintroduces dirt to the tape drive and you might not clean the drive. To
make sure that you know when your cleaning cartridge expires, make a
notation on the cleaning cartridge each time you clean the tape drive.
