Handling the Floppy Disk Drive(FDD) and Floppy Disk
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 commer-
cially-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 humid-
ity, 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 unread-
able.
• 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).
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.
