Setting the Write-Protect Tab on 12/24 GB 4 mm Tape Cartridges
Set the write-protect tab on a tape cartridge so that you do not accidentally lose
information. The write-protect tab on the tape cartridge controls write-protection. When
the write-protect tab on a tape cartridge is closed, information can be read from the
tape and written to it. When the write-protect tab on a tape cartridge is open,
information can be read from the tape, but not written to it.
1 Write-protect tab closed: Write enabled
2 Write-protect tab open: Write disabled
Erasing 12/24 GB 4 mm Data Cartridge
Most bulk eraser devices cannot erase 12/24 GB 4 mm data cartridges. To properly
erase an 12/24 GB 4 mm data cartridge with a bulk eraser device, the erasure rating
must be at least 3900 oersted.
Environmental Considerations for 12/24 GB 4 mm Data Cartridges
This section describes operating and storage conditions including temperature, relative
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.
Condition Operating Ranges Storage Shipping
Temperature 60°F-90°F (16°C-32°C) 41°F-90°F (5°C-32°C) -40°F-126°F
(-40°C-52°C)
Relative Humidity
(non-condensing) 20%-80% 20%-80% 20%-80%
Maximum Wet Bulb 79°F (26°C) 79°F (26°C) 79°F (26°C)
