ATIP: At least two meanings:

  1. Asian Technology Information Program (ATIP)
  2. Absolute Time In Pre-groove -- from http://knowhow.cdfreaks.com/article.php?ID=122:

What is ATIP and how does it work as copy protection? Posted by DoMiN8ToR on Sunday, October 21 2001 Question answered by G@M3FR3@K

Every CD-R has important info on the disc itself which is called ATIP (Absolute Time In Pre-groove) or pre-groove for short. Without this data/info the CD-R cannot be used by a writer. The ATIP contains the following info:

  • The capacity of the CD-R
  • The manufacturer of the CD-R
  • The type of the CD-R (eg. Audio only)
  • Supported writing speeds
  • Absolute lead-in time
  • Last possible address where data can be written
  • etc...

Only a CD-Writer can read the ATIP (because like I said before this ATIP is only needed when writing a CD-R).

The ATIP protection is based on this fact: when the game starts it checks if there's ATIP info present: if so then it will presume it's a CD-R disc and will not play. However a normal CD-ROM cannot read this ATIP and will of course 'say' that this data is not present: thus the copy will work...
