time but will playback in most CD players.
CD-R discs can be recognized by the following logos:

Recordable
CD-RW (multiple recording)
CD-RW discs are able to be recorded onto many
times but will only playback in CD players offering
CD-RW compatibility. Products that offer CD-RW

Notes:
• Some DVD players cannot playback CD-R discs
and CD-RW discs because of laser power differ-
ences.
• Some CD players may be able to playback finalized
CD-RW discs.
• Some CD players can not play finalized CD-R discs
because of the low reflectivity of such discs.
Which discs to use:
The CDR300 is able to record onto any 1X or 2X com-
patible CD-R and CD-RW disc, including discs for
Consumer use and Professional (computer) discs.
The CDR300 records according to the Orange Book
specification. Every CDR disc sold should be according
to the Orange Book specification and therefore compat-
ible with the CDR300.
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 impor-
tant. 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 74 minutes (80 min-
utes) are out of the Orange Book standard and may
perform below your expectations.

the record side.
