CDR1000—Owner’s Manual
Operating Notes
This section contains information that will help you get the most from your CDR1000.
Playback
The CDR1000 can play prerecorded audio CDs and unfinalized or finalized CD-R or
CD-RW discs. Only Session 1 of a multi-session disc can be played.
Recording
The CDR1000 can record onto CD-R and CD-RW discs that feature one of the follow-
ing logos.
The CDR1000 can record up to 99 tracks per disc and up to 99 indexes per track, the
standard for audio CDs. The minimum length of a track is four seconds, so even if you
stop recording before four seconds is up, the final track will be four seconds long.
OPC
Each time an unfinalized CD-R or CD-RW disc is loaded, the CDR1000 performs an
OPC (Optimum Power Control) test to determine the optimum laser power necessary
for recording. During OPC testing, “OPC” appears on the display and no other func-
tions can be used until testing is complete.
For unfinalized CD-R discs, if OPC has been performed 94 times, finalization is per-
formed automatically. If an unfinalized CD-R disc on which OPC has been performed
more than 95 times is loaded, “OPC OVER” appears on the display, which means that
the disc cannot be used for recording. For this reason, we recommend that you do not
load unfinalized CD-R discs into the CDR1000 unnecessarily.
TOC & PMA
CDs store track and index numbers, track start and end times, and track length infor-
mation in a TOC (Table of Contents), which is read each time a disc is loaded into a CD
player. Since the final TOC cannot be written to disc until all tracks have been recorded,
a temporary table of contents is written to the PMA (Program Memory Area), an area
of the disc reserved specifically for this purpose. While the temporary table of contents
is being written, “WAIT” appears on the display and no other functions can be used.
When a partially recorded disc is loaded, the CDR1000 reads the temporary table of
contents to see what’s already been recorded and determine the time available for addi-
tional recording.
