3 Tape cartridges and magazines
This chapter explains which media to use with the tape library, and how to label and write-protect
your tape cartridges. Careful labeling and handling of the tape cartridges will prolong the life of
the tape cartridges and the tape library.
Use the data and cleaning tape cartridges designed for your model of tape library.
The LTO-3 and later tape drives support both rewriteable and WORM data cartridges.
Write-Once, Read-Many (WORM) data cartridges provide an enhanced level of data security
against accidental or malicious alteration of data on the tape cartridge. The WORM data cartridge
can be appended to maximize the full capacity of the tape cartridge, but you will be unable to
erase or overwrite data on the cartridge. WORM data cartridges are clearly identified by their
distinctive, two-tone cartridge color. To see whether your backup or archive software application
supports WORM cartridges, see the Storage Media website at
Using and maintaining tape cartridges
with a magnetic servo signal. This signal is required to use the cartridge with the tape drive. Keep
magnetically charged objects away from the cartridge.
To ensure the longest possible life for your data cartridges, follow these guidelines:
Use only the data cartridges designated for your device.
Clean the tape drive when the Clean drive LED is illuminated.
Do not drop a cartridge. Excessive shock can damage the internal contents of the cartridge
or the cartridge case itself, making the cartridge unusable.
Do not expose data cartridges to direct sunlight or sources of heat, including portable heaters
and heating ducts.
The operating temperature range for data cartridges is 10 to 35º C. The storage temperature
range is -40 to +60º C in a dust-free environment in which relative humidity is always between
20 percent and 80 percent (non-condensing).
If the data cartridge has been exposed to temperatures outside the specified ranges, stabilize
the cartridge at room temperature for the same length of time it was exposed to extreme
temperatures or 24 hours, whichever is less.
Do not place data cartridges near sources of electromagnetic energy or strong magnetic
fields such as computer monitors, electric motors, speakers, or X-ray equipment. Exposure
to electromagnetic energy or magnetic fields can destroy data and the embedded servo
code written on the media by the cartridge manufacturer, which can render the cartridge
Place identification labels only in the designated area on the cartridge.
Labeling tape cartridges
The device contains a bar code reader that reads the tape labels and stores the inventory data
in memory. The device then provides the inventory information to the host application, OCP, and
RMI. Having a bar code label on each tape cartridge enables the bar code reader to identify the
Do not degauss LTO data cartridges! These data cartridges are pre-recorded
Use only Ultrium Universal cleaning cartridges.
