I was wondering how copy protection is done on commercial disks.
How are the following implemented AND/OR cracked?
1. Long tracks.
2. No sector header.
3. No sync mark.
4. Funny end of track gaps.
5. The infamous mangled MFM format and mangled bit pattern.

Can anyone tell me how to make a syncro express? I have some ideas, but
I am not sure if they are right.
