Cleaning the Disk Drive Read/Write Head
●The M.D.R. employs precise magnetic head to read
data. The magnetic head will pick up a layer of
magnetic particles from the disks for an extended
period of time. The stained magnetic head 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.
NOTE:
Ask your Yamaha dealer about the availability of proper head-
cleaning disk.
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). If you attempt to modify the disk when
the write-protect tab is set to “on” position, “Prot
(Protected)” will appear on the LED display in the
M.D.R. section indicating that the operation is not
possible.
Also please check if the write-protect tab is set to
“off” position when you record data.

■Data backup
Yamaha recommends that you keep two copies of
important data on separate floppy disks using Disk
copy function. To make a backup disk use the Disk
Copy function on page 45.
Improved Potentiality of the M.D.R.
The M.D.R. of the EL-200 begins reading all data
as soon as you insert a disk into the floppy disk slot.
Thus, inserting a disk causes to produce a sound
(reading sound) indicating that the M.D.R. is in the
reading process.
You can start playback as soon as you insert the
disk.
NOTE:
Ejecting the disk will lose the data loaded from the disk except
for the currently selected and played back song.
NOTE:
The time reading sound is produced is in proportion to the
amount of data recorded in the disk. You can eject the disk
whenever you are not using the M.D.R. and don’t want to be
bothered with the reading sound.
