Yamaha CVP-900 Cleaning the Disk Drive Read/Write Head, About the Floppy Disks

CVP-900
•Never attempt to remove the disk or turn the power off
when the data is being written to the floppy disk.
Doing so can damage the disk and possibly the disk
drive. 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.
• 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.
• 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.
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).
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 to
Disk function on page 150.
