Cartridge Storage Conditions

Before you use a cartridge, let it acclimate to the normal operating
environment for 24 hours.
Ensure that all surfaces of the cartridge are dry before use.
Do not expose the cartridge to moisture or direct sunlight.
Always ship or store a cartridge in the vertical orientation and inside a
jewel case to prevent damage to the tape edge.
Do not expose recorded or blank cartridges to stray magnetic fields (for
example, terminals, motors, video equipment, X-ray equipment, or fields
that exist near high-current cables or power supplies). Such exposure can
lead to loss of data or render the blank cartridge unusable.
Maintain the environmental conditions outlined in the Table 11.
