Setting the Write-Protect Tab on 12/24GB 4mm Tape Cartridges
It is necessary to 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 12/24GB 4mm Data Cartridge
Most bulk eraser devices cannot erase 12/24GB 4mm data cartridges. In order to
properly erase an 12/24GB 4mm data cartridge with a bulk eraser device, the
erasure rating must be at least 3900 oersted.
Environmental Considerations for 12/24GB 4mm 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 12/24GB 4mm 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 12/24GB 4mm tape cartridges are operated,
stored, or shipped outside the temperature or humidity ranges shown in Table 2-1 on
page 2-20.
