Handling the Floppy Disk Drive(FDD) and Floppy Disk
Precautions
Be sure to handle floppy disks and treat the disk drive with 
care. Follow the important precautions below.
■
 Compatible Disk Type
3.5" 2DD and 2HD type floppy disks can be used.
■
 Inserting/Ejecting Floppy Disks
●
To insert a floppy disk into the disk drive:
• Hold the disk so that the label of the disk is facing upward 
and the sliding shutter is facing forward, towards the disk 
slot. Carefully insert the disk into the slot, slowly pushing it 
all the way in until it clicks into place and the eject button 
pops out.
●
To eject a floppy disk:
•  Before ejecting the disk, be sure to confirm that the FDD is 
stopped (check if the LED below the floppy disk slot is off). 
Press the eject button slowly as far as it will go; the disk 
will automatically pop out. When the disk is fully ejected, 
carefully remove it by hand. 
• Never attempt to remove the disk or turn the power off dur-
ing recording, reading and playing back. Doing so can 
damage the disk and possibly the disk drive. 
• If the eject button is pressed too quickly, or if it is not 
pressed in as far as it will go, the disk may not eject prop-
erly. The eject button may become stuck in a half-pressed 
position with the disk extending from the drive slot by only 
a few millimeters. If this happens, do not attempt to pull out 
the partially ejected disk, since using force in this situation 
can damage the disk drive mechanism or the floppy disk. 
To remove a partially ejected disk, try pressing the eject 
button once again, or push the disk back into the slot and 
then repeat the eject procedure.
• Be sure to remove the floppy disk from the disk drive 
before turning off the power. A floppy disk left in the drive 
for extended periods can easily pick up dust and dirt that 
can cause data read and write errors.
■
 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 eventu-
ally cause read and write errors. 
●
  To maintain the disk drive in optimum working order 
Yamaha recommends that you use a commercially-avail-
able dry-type head cleaning disk to clean the head about 
once a month. Ask your Yamaha dealer about the avail-
ability 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 sur-
face 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 hous-
ing.
• 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 dam-
aged. To make a backup disk use the Disk Copy function 
on page157. 
• When the TYROS is turned on, the LED below the floppy disk 
slot will be lit indicating that the Disk Drive is ready to use. 
This lamp is always on when the power 
is on, regardless of the disk operation. 
DISK IN USE
This lamp lights during disk read/
write operations, such as when a 
disk has been inserted, during 
recording, playback, formatting, etc.

tected)
