Cleaning the Disk Drive
Read/Write Head
●
Clean the read/write head regularly. This
instrument employs a precision magnetic
read/write head which, after an extended period of
use, will pick up a layer of magnetic particles from
the disks used that will eventually cause read and
write errors.
●
To maintain the disk drive in optimum working
order Yamaha recommends that you use a
commercially-available dry-type head cleaning
disk to clean the head about once a month. Ask
your Yamaha dealer about the availability of
proper head-cleaning disks.
Never insert anything but floppy disks into
the disk drive. Other objects may cause
damage to the disk drive or floppy disks.
About the Floppy Disks
■
To handle floppy disks with care:
Do not place heavy objects on a disk or
bend or apply pressure to the disk in any
way. Always keep floppy disks in their
protective cases when they are not in use.
Do not expose the disk to direct sunlight,
extremely high or low temperatures, or
excessive humidity, dust or liquids.
Do not open the sliding shutter and touch
the exposed surface of the floppy disk
inside.
Do not expose the disk to magnetic fields,
such as those produced by televisions,
speakers, motors, etc., since magnetic fields
can partially or completely erase data on the
disk, rendering it unreadable.
Never use a floppy disk with a deformed
shutter or housing.
Do not attach anything other than the
provided labels to a floppy disk. Also make
sure that labels are attached in the proper
location.
■
To protect your data (Write-protect Tab):
To prevent accidental erasure of important data,
slide the disk's write-protect tab to the "protect"
position (tab open). If you attempt to modify the
disk when the write-protect tab is set to "on"
position, "Prot (Protected)" will appear on the LED
display in the M.D.R. section indicating that the
operation is not possible.
