Description 2-9
Data Cartridge
The data cartridges used in the DTL7000 Series are housed in
4-inch plastic cases and employ 1/2-inch metal particle tape.
Table 2-6 describes and lists the media cartridges that can be
used with the four models.
The Write-Protect switch prevents accidental erasure of data.
If the switch is moved all the way to the left, the cartridge is
write-protected and the drive cannot write to, or erase data
from, the cartridge. The small orange rectangle will be visible
whenever the cartridge is write-protected. Additionally, an
arrow (beneath the orange rectangle and above the two lines
on the switch), lets you know that data cannot be written to
the cartridge. If the switch is moved all the way to the right,
the cartridge is write-enabled and the drive can write data to,
or erase data from, the cartridge. The orange rectangle will not
be visible whenever the cartridge is write-enabled. On the
right side of the write-protect switch an arrow over one line
indicates that if you slide the switch to the right, data can be
written to the cartridge. Refer to Figure 2-4 on page 2-10.
