Storing Cartridge Tapes
Observe the following precautions when storing cartridge tapes:
•
Follow the requirements listed in Table 4-2 on page 4-2 for storing cartridge tapes.
•
Do not store cartridges near maximum temperature and humidity for more than
three months.
•
Do not store cartridges near a strong magnetic field such as a permanent magnet
or an electromagnet.
•
Do not store cartridges in direct sunlight.
Setting the File-Protect Thumbwheel
You can position the file-protect thumbwheel on a cartridge to prevent erasing or
altering data on the tape. When the flat surface (with the white dot) is parallel with the
edge of the cartridge, an application program can read data from the cartridge tape but
cannot write (or erase) data on the tape. The unprotected position is 180 degrees
around from the file-protected position (see Figure 4-1).
To stop protecting the data on the cartridge, use your thumb or fingernail to roll the
file-protect thumbwheel until the white dot is inside the cartridge. When the white dot is
not in view, an application program can both read data from and write data to the
cartridge tape.
