Why would you do that?

Wrong section maybe (Optical Storage Technical Discussion maybe).

all clone software (Alcohol 120%,CDRWIN,Clone…) can create 1:1 copy from CD
if i can write directly on ATIP , i can protect cd from copy . (a program on cd can check that data )
i know there is no way to this , with normal SCSI-MMC functions .
device can read that section , why not can write on it ?
