POINT=AO PMIN = TNO of first datatrack on disk
PSEC = Zero
PFRAME = Zero
POINT=A1 PMIN = TNO of last datatrack on disk
PSEC = Zero
PFRAME = Zero
POINT =A2 PMIN = Abs. Time of Lead-Out
PSEC = Abs. Time of Lead-Out
PFRAME = Abs. Time of Lead-Out
For the Green Book (CDI):
POINT =AO PMIN = Number of CDI-tracks on disk + 1
PSEC = 10 (BCD)
PFRAME = Zero
POINT =A1 PMIN = TNO of last audiotrack on disk or

When a disk is read-in, the TOC is loaded into memory of the
drive-unit. From there-on the servo-uP knows exactly where it is
on the disk by reading the Subcode.
The CD reader unit does not make a distinction between all the
different disk-colors. As far as the unit is concerned, the Red and
the Yellow disks are the same. It knows about three disk types:
Red/Yellow, Green and Bridge, which is Green combined with
Red and/or Yellow.. The distinction is made with the PSEC value
when POINT = AO:
Red/Yellow: PSEC = 00 (BCD)
Green: PSEC = 10 (BCD)
Bridge: PSEC =20(BCD)
(For Bridge Disk, see Chapter 7 p 37: Disk Types)
