IBM only supports using DVD discs supplied by IBM. Data grade media is the
only type of media that should be used for backup and data processing. Saving
money by using generic media for data purposes will do little to save your
business if your data is destroyed and your backup discs fail because of inferior
media. For best performance, only order discs for your drive that are
recommended in Table 15.
To order DVD discs in the United States and Canada, call 1-888-IBM-MEDIA. To
order cartridges in other locations, contact your local provider of IBM storage
products or visit the following URL:

Recommendations for Disc Usage
The following list describes recommended guidelines that will help to protect your
data and prolong the life of your discs and the installed DVD-RAM drives:
v Back up and then discard any disc that repeatedly produces error messages (the
error information is in the System Error Log).
v Do not touch the disc data surface, handle by the disc edges to prevent against
disc damage and data loss.
v Use only one label on a disc. Apply labels only to top surface. Multiple or
poorly placed labels can clog the drive load mechanism.
v Discard any discs that may have been damaged due to mishandling.
v Make sure the environment is kept clean and constant. Do not operate in a
dusty environment and always maintain a constant environmental atmosphere.
A consistent storage and operating environment reduces media exposure to
climatic stress.
v Printers and copiers can produce paper and toner dust. Locate the unit away
from these items. High traffic areas near hallways and doors can also produce
excess dust and dirt.
v All important information should be recorded on the disc label. Information,
such as the model and number of the system or DVD-RAM drive, the date, the
density, any error statistics, and a log number should be included. The operating
environment and format mode should also be noted.
v Position the enclosure in a location where the temperature is relatively stable, for
example, away from open windows, fan heaters and doors.
v Avoid leaving discs in severe temperature conditions, for example in a car
standing in bright sunlight.
v Avoid transferring data (reading from or writing to discs ) when the temperature
is changing by more than 10°C (18°F) per hour.
v After either the disc or drive has experienced an extreme change of temperature
(more than 15°C, 27°F), do not use the drive for at least two hours to allow the
temperature of the device and media to stabilize.
