Chapter 4  Precautions

The magneto-optical disk cartridges are equipped
with a DATA PROTECT switch (red tab) to
prevent accidental erasure of data on the disk or
inadvertent writing of unwanted data. Slide this
switch in the direction of the arrow as illustrated
below to enable the write protect function.
You can still read the data contained on the disk,
but will not be allowed to write on or erase the
disk. Return the switch to its original position to
disable the write protect.

DATA PROTECT
switch

Make it a practice to leave the write protection
enabled when you do not foresee the need to
write on the disk.

Dust and stains may accumulate on MO disks
when they are used for a long period of time. To
avoid resultant data read/write errors, use an
optional disk cleaner. To maintain the high
performance and prolong the useful life of your
MO disk, cleaning at least once every three
months is recommended.

Attention
In the subsystem, preventive measures are taken
to guard against dust. It is unnecessary to clean
the optical lens of your subsystem. Using a lens
cleaning cartridge may damage the subsystem.
