Disc Handling And Precautions - Denon CDR-1000 Operating Instructions Manual

ENGLISH
Digital Copies
A CD-R/RW disc onto which has been recorded using the digital input cannot be further digitally recorded (i.e., copied) onto a
separate CD-R/RW disc or MD, etc.. This is a standard established by the SCMS (Serial Copy Management System).

Track Numbers: Auto Track Function
Recording in the Synchro-recording mode (e.g., disc Synchro-recording, track Synchro-recording, and auto finalization recording)
results in the track numbers being automatically associated. The manner in which the track numbers are associated will differ as
follows for digital recording and for analog recording depending on the conditions.
Recording from a digital input
2
When making a digital recording from a CD, MD or DAT, a track number that is the same
as the original track number will automatically be associated. (This system automatically
detects the track switching number that has been recorded to the CD, MD or DAT and
switches the track number.)
• When recording from a satellite broadcasts or other digital equipment, the detection of
a blank portion of about 2.7 seconds or longer, the same as when making recordings
with an analog input, will result in the operation of the auto track function and the
automatic association of the track number.
• A blank portion is regarded as having a recording level of –55 dB or less.
• The track number might not switch correctly when there is a lot of noise in the blank
portion between tracks.
• The track number might change when the signal level is very low within the track.
Recording from an analog input
2
Track numbers will automatically be associated when a blank portion of about 2.7
seconds or longer is detected.
• When the input signal is affected by noise or there is some other interference,
the track number might not change at the correct position.
• The track number might change when the signal level is very low within the
track.
The on/off setting of the auto track function is possible in manual recording. (See
"Auto track increment" on Page 17.)
NOTES:
• DAT track selection signals (Start ID) are recorded slightly after the beginning of tracks, so when DATs are recorded as
such, the beginning of the first track may be missing and the track numbers may only change after the tracks begin. In
such cases, move the DAT Start ID to the proper positions before recording the DAT.
• When recording an analog source that contains a very low level signal within the track, or a digital source other than
CD/MD/DAT, switch off the auto track function then make a manual recording and associate the track numbers manually.
• When the recording level is set too low while recording an analog source or a digital source other than CD/MD/DAT, the
track numbers might not be associated at the correct position. Please set a suitable recording level. (See "Setting of the
Recording Level" on Page 11.)

Finalization Processing of CD-R Discs
After the recording of a CD-R disc is completed, finalization
processing is required to enable it to be played on an ordinary
CD player.
Recording is possible.

DISC HANDLING AND PRECAUTIONS

Disc Handling
Avoid touching the surface of the disc when inserting or
removing it.
Be careful not to get
fingerprints on the signal
recording surface.
Disc Cleaning
When the disc has become marked with fingerprints or dirt,
2
wipe it clean before use. The dirt will not affect the signal of
the disc, but the sound quality may drop and there may be
breaks in the sound. Note that when the surface of a CD-
R/RW disc is dirty, it may not record properly.
To wipe the disc clean, use one of the disc cleaning sets
2
available on the market or a soft cloth.
Lightly wipe in the direction Do not wipe in a circular
from centre to outside. manner.
Storage Precautions
• Be sure to eject the disc after playing.
• Always return the disc to its case to avoid dust, scratches,
and misshaping.
• Do not leave the disc in the following places:
1. Where it will be exposed to direct sunlight for long
periods.
2. Where there is a lot of dampness and dust.
3. Where it will be exposed to heat such as from a heater.
NOTES:
• Once a CD-R disc has been finalized, additional
recording will no longer be possible.
• The information that has been recorded to a CD-R
disc cannot be erased.
Finalization Processing of CD-RW Discs
CD-RW discs cannot be played on an ordinary CD player,
even with finalization processing. Playback is possible
only on CD recorders or players suited for use with CD-
RW discs.They can only be played on a player that is
suited for use with CD-RW discs. Also note that CD-RW
discs can be erased after being finalized.
NOTES:
• Do not attach commercially available disc labels or
other seals on the disc. Doing so may make it
impossible to record or play the disc properly.
• Do not use record spray or static electricity prevention
products. Do not use benzene, thinner, or other
volatile chemicals.
Handling Precautions
• Do not allow fingerprints, oil, or dirt to adhere.
• Be careful not to scratch the surface, especially when
removing or returning the disc to the case.
• Do not bend the disc.
• Do not heat the disc.
• Do not enlarge the center hole.
• Do not write on the label surface (i.e., printed side) with a
ballpoint pen or pencil.
• Water droplets may form on the surface of the disc when it
is suddenly brought from a cold place such as outdoors to a
warm place. If this happens, do not dry the disc with a hair
dryer.
