SecuROM NOT SECURE ROM
How it works:
It is the combination of an electronic fingerprint applied to each disc and a sophisticated encryption technology for authentication differentiating a legitimate CD-ROM from a pirated disc. Unlike SafeDisc protection , the SecuROM protection does not rely on the deliberate introduction of unreadable errors onto the disc; consequently: any CD-Reader supporting RAW reading (and ability to read SubChannel) can do the job in a fast way.
How to recognize it:
Most of the time, theses following files can be found on that type of CD : CMS16.DLL, CMS_95.DLL or CMS_NT.DLL ; but you may find CD protected with SecuROM that don’t contain theses files.
So, another way to reckon it is to look at the barcode of CD , you will be able to distinguish a little “logo” with name “DADC” on it , (it only applies with Data CD since AudioCDs pressed by Sony also include this logo) (e.g “Hachette 2000 Encyclopedie” is a French SecuROM protected CD that only contains “DADC” logo).
Update: Recently Sony updated the SecuROM protection in order to make it much more difficult to duplicate. There’s a new version of Securom (used in e.g. V-Rally 2, Diablo II, Ground Control, Music 2000, Soulbringer). There are NO cms*.* files anymore and on some CDs there isn’t even the DADC-logo. This time the protection checks for CDR media and when finds it crashes the application. CloneCD latest builds can duplicate the new SecuROM but you need to install the backup only from CD-ROMs!
The new Securom files are
They are copied to Windows system directory during installation!

What is ATIP and how does it work as copy protection ?

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
Only a CD-Writer and some DVD ROMs can read the ATIP information.
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…
Having said that there is now a newer version of the Secu - ROM version 4.X which currently is not copiable with the use of the Clone CD alone directly.
