Always let a cartridge acclimate to the operating environment before you use it. Acclimation is necessary for any data cartridge that has been exposed to a different humidity environment or to a temperature change of 11°C (20°F) or more. Place the cartridge, with its container, in the operating environment for as long as it has been away from the operating environment or for 24 hours, whichever is less.

Operating the 12/24GB 4mm Tape Drive in Harsh Environments

The tape drive is ideally suited to streaming operations rather than tape movement operations involving multiple stops and starts and random searches. You should use streaming movement whenever possible.

Do not use for archiving any tape that was previously used outside the ranges specified in ªEnvironmental Considerations for 12/24 GB 4 mm Data Cartridgesº on page 32 for an extended period of time. Exposure to the new environment deteriorates the magnetic and physical strength of the tape. Do not store important data on a tape that was used outside the specified ranges. For reliable archiving, transfer the data to a new tape.
