Data Cartridge Erasure
Most bulk eraser devices do not have the capability to erase the 4mm data cartridge. To
properly erase a 4mm data cartridge with a bulk eraser device, the erasure coercivity
rating must be a minimum of 3900 Oersted.
Storage and Shipping Environments
Before using a tape cartridge, let it acclimate to the operating environment by placing
the cartridge in the operating environment for as long as it has been away from the
environment or for 24 hours, whichever is less. (To determine the appropriate operating
environment, see "Tape Drive Environment and Use" on page 2.)
Acclimation is necessary for any data cartridge exposed to a different humidity
environment or to temperature changes of 11°C (20°F) or more.
Retrieval of archived data should be performed on a tape unit that is clean and fully
operational. Try to make the recovery environment the same as the operating
environment. Allow tapes at least 24 hours to acclimate to environment of the tape unit.
The recommended environment for storage and shipment of 4mm data cartridges is
shown in Table 4.

Tape Cartridge Storage
Tape drives record data using densities similar to hard disk drives. Because most
computer systems are not located in a dust-free, climate-controlled environment, you
must exercise special care when dealing with tape cartridges and tape drives. They
need to be treated as a valuable asset used to protect your business data.
Use the following guidelines for storing your tape cartridges:
v Temperature and humidity should be kept constant at a level comfortable for you.
v Tape cartridges should always be stored 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
