1.6 Cartridges
A cartridge is a storage device that contains either magnetic tape or a cleaning ribbon inside a protective
case. The cartridge protects the tape or ribbon and makes handling easier. The two types of cartridges:
(1) cleaning cartridges and (2) cartridge tapes.
1.6.1. Cleaning Tapes
Cleaning cartridges are used to clean the recording heads of the tape drive with a cleaning ribbon.
1.6.2 Cartridge Tapes
Cartridge tapes hold magnetic storage media for the tape drive. A cartridge tape is a self-contained
plastic shell containing a spool of magnetic tape. These cartridges are used to record and read back
system data.
1.6.3 Humidity
To avoid condensation problems, allow a tape to stabilize at least two hours after a change in
humidity or temperature before using.
1.6.4 Life Expectancy of Tapes
DDS-certified media is electronically checked to withstand at least 2000 passes. Under optimum
environmental conditions (50% relative humidity, 22ºC), this is equivalent to about 200 to 300
backup operations. This rating takes into account that an area of tape might have several passes
during a backup. Sustained use at the low end of the humidity specification reduces the tape life.
1.6.5 Using Labels
Cartridge and magazine labels must be firmly stuck to the recessed label area and nowhere else.
To avoid a mechanism jam:
•
Labels must be firmly stuck and not peeling off or curling at the corners.
• Labels must be stuck only within the label area.
• A label must not be stuck on top of another label.
• Only use the labels that are supplied with the cartridges or magazine.
