9.5 DISC JUDGMENT

9.5.1 Tentative Judgment Using FZC
(Distinguishing Between CD/CD-R
and CD-RW)
The judgment is made before the Focus IN operation after the disc
is inserted.
FZC (SENS)
Judged that the disc is a CD-RW
if this period is less than 200 µs.
Bringing up the focus, the range of FZC is checked at that time.
It is judged that the disc is a CD/CD-R if FZC remains "H" for more
than 200 µs.
It is judged that the disc is a CD-RW if FZC is not detected or
intermittently detected.
