Some useful information about MDs and CDs

Types of MDs
Sound Cruise
Prerecorded MDs
These discs are for
playback only.
Recording on MDs
MDs are different to tapes
MDs give you control over how tracks are recorded and editing functions
allow you to change the contents of an MD after recording.
Unlike cassettes, you do not need to find an empty space to start
recording as all recordings start from the first available space. When the
MD fills up, you can use the editing functions to erase unneeded tracks.
You cannot record over tracks.
Limitations on digital recording
The serial copy management system (SCMS) prevents unlimited
recording of digital material.
Clear, relatively intact, digital recordings can be made when recording a
CD in this unit. So to protect the rights of the producer of the original
material, it is not possible to make a further recording from that MD to
another MD.
Analog recordings are unlimited by this system.
CD
(Long Play)
Advances in digital technology have now made it possible to record two
to four times the amount of stereo material on an MD.
Now you can record a maximum of 160 minutes of audio on an
80-minute MD using LP2 recording mode and 320 minutes using LP4
recording mode.
SP: Standard recording mode
LP2: Double the amount of material.
LP4: Four times amount of material.
The three modes can be used on the same MD.
Protecting your recordings
Move the switch to open the write protect hole. Close the hole when you
want to record or edit the MD again.

Apart from the time limitations, it is
possible to record up to 254 tracks on an
MD.

Glossary of terms
Analog
This is the method that phonographic records and cassettes use to
handle sound signals.
Digital
This is the usual method used by MDs and CDs to carry and record
sound signals. Digital recording can be of very high quality.
Editing
This refers to any post-recording changes made to the MD.
Marking
This is the act of adding track marks. It can be done automatically when
recording, or it can be done manually during recording or after recording
with the editing functions (DIVIDE).

times.
Track marks
These marks separate tracks. There can be up 254 marks on one MD.
They can be inserted automatically or manually during recording, and
they can be added (DIVIDE) or removed (COMBINE) with the editing
functions after recording.
UTOC
User table of contents. This is information the user can edit, such as text
and track positions.

editing.
Care and storage
Label MDs only as recommended. Extra labels and exposed adhesive
can cause malfunctions.
Do not open the shutter, and close it immediately if it accidentally opens.
Never touch the disc inside the MD cartridge.
Keep your MDs out of direct sunlight, humid and dusty places, and away
from the direct heat of heating appliances.
CD selection and care
