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.
