A CROSS-SECTION THROUGH A PARTIALLY RECORDED
CD-R OR -RW DISC.
After the first recording the recording area is divided (see figure
below).
• The “Lead-in”, “program area” and “Lead-out” areas are
present on every conventional prerecorded CD.
• For the partially recorded CD-R or -RW disc, the PCA and
PMA areas are incorporated in front of the Lead-in.
• Track numbers with associated absolute start and stop times
are stored in the PMA.
The possibility exists of making further recordings later. It would
also be possible to declare the disc as fully recorded. In which
case, the definitive table of contents (TOC) is written into the
Lead-in.
