And don't forget the P-channel is shifted by 1 sector forward.

To be perfectly precise (for people who follow this discussion) :

P channel activation should start one sector after start of gap and should end one sector after gap end ?

Hi,<br/>
<br/>
Those days, I try to code a little thing to parse a .CCD file.<br/>
I am sure that people here are very comfortable with some definitions<br/>

Ok,  I consider DataTracksScrambled is always  set to 0.

<t>I read the Annex B (p31).<br/>
<br/>
Scrambling seems to be a sort of obfuscation of data bits in a sector to prevent some bad schemes to appear.<br/>
<br/>
The document ECMA 130 tells us that sectors data should be scrambled.<br/>
