Retrieve archived data on a tape unit that is clean and fully operational. Try to
make the recovery environment the same as the operating environment. Let the
tapes acclimate to the environment of the tape unit for at least 24 hours.
The recommended environment for storage and shipment of VXA data cartridges
is shown in Table 3.

Tape drives record data using densities that are similar to those of hard disk
drives. Because most computer systems are not in a dust-free, climate-controlled
environment, you must use special care when dealing with tape cartridges and
tape drives.
Use the following guidelines for storing tape cartridges:
v Keep temperature and humidity constant at a level that is comfortable for you.
v Store tape cartridges in their protective cases. The storage case helps prevent
damage from dust and physical misuse. When the tape cartridges are not in use
or being stored, they should be in their storage cases and stood on edge in a
designated storage location. Do not stack cartridges on the flat side or stack
other items on top of the tape cartridges. Handle your tape cartridges with care
to reduce archival problems.
v Keep tape cartridge protective cases closed except when you insert or remove a
cartridge. Contamination can build up and be transferred to the tape cartridge if
the protective case is left open.
v Exercise stored tapes at least once every 12 months. Run the tape from
Beginning of Data (BOD) to End of Data (EOD) and back to BOD at normal
operating speeds. Tapes that are stored in a warmer environment should be
exercised more frequently.
v Sunlight can damage the tape and the cartridge shell. Store tape cartridges out
of the direct sunlight
