5.3.2 Write protect tab
Moving the write protect table determines whether to enable or disable writing of
the optical disk cartridge. Use a fingernail to move the write protect tab (it must be
completely moved to the end because there is play in the middle).
Figure 5.5 shows the write protect tab location on the optical disk cartridge and the
moving state of the write protect tab (see "write enabled" and write disabled"
entered on the label).
Note:
The hatched part indicates the write protect tab location.
