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.
Using Floppy Disks
Be sure to follow these precautions when using
floppy disks:
• 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.
Protecting 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, a “Disk write protected!” or “Disk
error!” message appears in the display,
indicating that the operation is not possible.
(Select “OK” at the prompt, and change the tab
setting, if desired.)
Data Backup
For maximum data security Yamaha
recommends that you keep two copies of
important data on separate floppy disks. This
gives you a backup if one disk is lost or
damaged. To make a backup disk use the Disk
Copy function on page 111.
