Music Disk Recorder

Cleaning the Disk Drive Read/Write Head

● This instrument employs a precision read/write

magnetic head. 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 commer-

cially 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 exces-

sive 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 by using this

function. To make a backup disk use the Disk Copy

function on page 92.

Improved Potentiality of the M.D.R.

The M.D.R. of the EL-100 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.

The improvement of the M.D.R. allows you to start

song playback immediately, to be free from the

reading sound during playback and to record the

song playback using the several song numbers with

the Next Song function.

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.
