Chapter 4. Using the Media
This chapter describes the types of tape cartridges to use with the 7207 Model 122
4GB External SLR5 Quarter-Inch Cartridge Tape Drive. It gives guidelines for their
usage, defines recommended storage and shipping environments, lists data
cartridge compatibility, and describes variables that affect tape cartridge efficiency.
It also tells how to set the write-protect switch.
Types of Tape Cartridges
The 7207-122 Tape Drive is shipped with a media kit that contains the following
cartridges.
Data Cartridge
Use the SLR5-4GB quarter-inch data cartridge to save or restore programs or data.
For a list of compatible data cartridges, see “Data Cartridge Compatibility” on
page 20.
Test Cartridge
Use the specially labeled SLR5-4GBSL test tape cartridge to perform diagnostic
procedures on the drive. Do not use it to save or restore programs or data.
Cleaning Cartridge
Use the specially labeled cleaning cartridge to clean the 7207-122 Tape Drive. For
instructions about how to clean the 7207-122 Tape Drive see “Cleaning the Tape
Drive” on page 16.
To order additional cartridges, refer to “Ordering Tape Cartridges” on page 24.
Data Cartridge Usage and Erasure
Do not touch the tape material in the data cartridge. Any substance transferred to
the tape by touching could cause loss of data.
Do not use worn or noisy cartridges. If a cartridge generates frequent read or write
errors, replace the cartridge.
The 7207-122 Tape Drive erases previously used tapes as it overwrites them. The
tape drive overwrites from the beginning of the tape or it can append to the end of
existing data.
Data cartridges that contain the QIC-4GB-DC (and below) format may be bulk
erased. To properly erase a QIC-4GB-DC data cartridge with a bulk eraser device,
the erasure coercivity rating must be 3000 oersted minimum.
