PSR-450 Owner’s Manual
Handling the floppy disk drive (FDD) and floppy disks
This instrument features a built-in floppy disk drive (on the front panel). It lets you save original data you’ve created on the
instrument to floppy disk, and allows you to load data from floppy disk to the instrument.
Be sure to handle floppy disks and treat the disk drive with care. Follow the important precautions below.
■Floppy disk compatibility
3.5" 2DD and 2HD type floppy disks can be used.
■Formatting a floppy disk
●If you find that you are unable to use new, blank disks or old
disks that have been used with other devices, you may need
to format them. For details on how to format a disk, see page
59. Keep in mind that all data on the disk will be lost after for-
matting. Make sure to check beforehand whether or not the
disk contains important data.
•Floppy disks formatted on this device may or may not be useable as
is on other devices.
■Inserting/removing Floppy Disks
●Inserting 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.
• When the power is turned on, the drive lamp (at the bottom left of
the drive) lights to indicate the drive can be used.
•Never insert anything but floppy disks into the disk drive. Other
objects may cause damage to the disk drive or floppy disks.
●Removing a floppy disk:
• After checking that the instrument is not accessing* the
floppy disk, firmly press the eject button at the lower right of
the disk slot all the way in.
When the floppy disk is ejected, pull it out of the drive. If the
floppy disk cannot be removed because it is stuck, do not
try to force it, but instead try pressing the eject button
again, or try re-inserting the disk and attempt to eject it
again.
* Access of the disk indicates an active operation, such as record-
ing, playback, or deletion of data. If a floppy disk is inserted while
the power is on, the disk is automatically accessed, since the
instrument checks whether the disk has data.
• Do not remove the floppy disk or turn off the instrument itself
while the disk is being accessed. Doing so may result not only in
loss of data on the disk but also damage to the floppy disk drive.
Be sure to remove the floppy disk from the disk drive before turn-
ing off the power. A floppy disk left in the drive for extended peri-
ods 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 parti-
cles 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.
■ About floppy disks
●Handle floppy disks with care, and follow these precautions:
•Do not place heavy objects on a disk or bend or apply pres-
sure 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 mag-
netic 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).
When saving data, make sure that the disk’s write-protect
tab is set to the “overwrite” position (tab closed).
●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.
NOTE
NOTE
This lamp is always on when the power is on,
regardless of Disk operation.
This lamp lights during disk read/write operations, such as when a
disk has been inserted, during recording, playback, formatting, etc.
