Disk Operations
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.
■
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).
Using the Floppy Disk Drive (FDD) and Floppy Disks
• When the PSR-550 is turned on, the LED below the floppy disk
slot will be lit indicating that the Disk Drive is ready to use.
●
To eject a floppy disk:
• Before ejecting the disk, be sure to confirm that the
FDD is stopped (check if the DISK IN USE lamp 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.
• 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
properly. 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.
●
Never attempt to remove the disk or turn the power off
during recording, reading and playing back. Doing so
can damage the disk and possibly the disk drive.
●
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.
●
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.
Write protect tab
ON (locked or
write protected)
Write protect tab
OFF (unlocked or
write enabled)
DISK IN USE
This lamp lights
during disk read/
write operations,
such as when a
disk has been
inserted, during
recording,
playback,
formatting, etc.
This lamp is always on
when the power is on,
regardless of the disk
operation.
