humidity, and maximum wet bulb data.
Attention: The manufacturer specifies a set of temperature and humidity ranges in
which the 12/24 GB 4 mm data cartridge can operate with ease. Only
regular cleaning procedures are required when operating the cartridge
within this range. The risk of possible data loss is increased if 12/24 GB 4
mm tape cartridges are operated, stored, or shipped outside the
temperature or humidity ranges shown in the following table.
