4.9 Description of the Tape Cartridge
The CompacTape III tape cartridge is a 4-inch, gray, plastic cartridge containing 1100
feet of 1/2 inch magnetic metal particle tape.
4.9.1 Cartridge Write-Protect Switch
The tape cartridge has a Write-Protect switch to prevent accidental erasure of data.
Before you load the tape cartridge into the drive, position the write-protect switch on
the front of the cartridge (Figure 4-6). The switch can move to the:
• Left, so the cartridge is Write-Protected
• Right, so the cartridge is Write-Enabled
When you slide the switch to the left, the small orange rectangle is visible. This means
data cannot be written to the tape. The arrow (beneath the orange rectangle and over the
two lines on the write-protect switch) lets you know that data cannot be written to the
tape.
On the right side of the write-protect switch is another symbol: an arrow over one line.
This symbol indicates that if you slide the write-protect switch to the right, data can be
written to the tape.
Figure 4-6 shows the write-protect switch on the tape cartridge.
