Note(s):
a. The Netra 20 DDS-4 DAT drive can read DDS-1 formatted tapes but cannot write
DSS-1 formatted tapes.
b. The Netra 240 DAT72 drive does not support DDS-1 or DDS-2 formatted tapes.
When handling and storing tape cartridges, observe the following precautions:
• Keep cartridges away from anything magnetic.
• Store in a clean, dust-free environment, upright on edge rather than flat.
• Store in protective covers when not in use.
• Keep out of direct sunlight and away from extreme heat, cold or humidity.
• Cartridge must be at room temperature before using.
• Never open the tape access door on the cartridge and touch the magnetic
recording surface.
To maintain reliability in the DAT tape drive unit, regular head cleaning is required.
After every 25 hours of tape operation the unit should be cleaned using a DDS
cleaning cartridge. See “Clean the DAT Tape Drive Unit Head,” Procedure 4.22.
