NOTE::
• Some DVD players can not playback CD-R discs and some
cannot playback CD-RW discs because of laser power differ-
ences.
• Some CD players may be able to playback fi nalized CD-RW
discs.
• Some CD players can not play fi nalized CD-R discs because
of the low refl ectivity of such discs.
Which discs to use:
The CDR420 is able to record onto any compatible
CD-R and CD-RW (AUDIO) disc. The CDR420 can
also record on 700MB, 80 minute computer discs 8X
or greater.
The CDR420 records according to the Orange Book
specifi cation. Every CDR disc sold should be accord-
ing to the Orange Book specifi cation and therefore
compatible with the CDR420.
In practice however, the quality of the recording
depends on the match between the disc used and the
writing strategy of the recorder. At 1X speed (stand
alone audio) the match between disc and recorder is
important. Higher recording speeds are less critical in
terms of recording quality.
Consumer CD Recorders can only record on CD-R
Audio discs and those discs are optimized for single
speed automatically. Professional CD Recorders can
use both Audio and Data discs. When using Data
discs, one should take care to use discs with a good
single speed compatibility.
Recording Capacity:
Discs with higher capacity than 80 minutes are out of
the Orange Book standard and may perform below
your expectations.
Compact disc care
The glossy side is the record side of the disc, and mat-
ted (dull) side is the label side.
Handle discs carefully so as not to damage or scratch
the record side.
Avoid placing discs in the following locations:
• In direct sunlight or near a source of heat such as
a heater.
• In a place that is damp or dirty.
• In a place which could be exposed to rain, such as
near a window.
Disc cleaning
Always keep the disc surface clean. Up to six billion
data units are recorded on the record side of the disc.
When cleaning the disc surface always be sure to use
a special compact disc cleaner and wipe as shown
below.
Wipe in a radial
direction.
Do not wipe in cir-
cumferential direc-
tion.
