ZamziBam.....I really hope english isn't your first language.

A couple of simple flaws to you grand plan


Flaw number one.

Cdrom read lasers are not poweful enough to later CDRW dye. That is a design necessity. If it wasn't, what a waste of time CDRW would be? You'd backup some data, the laser would read it to verify, but at the same time destroy it!

Flaw number two.

All cdroms and cdr/cdrw MUST conform to the Orange book. If it doesn't then it is incompatible. That's the whole point of a standard. Multi-dyed discs? Impossible to manufacture, let alone write to. How would your cd burner know when it hit a different dye?

Flaw number three.

Even if all of the above miraculously were solved, it would be utterly pointless as all you'd need to do is run from a cdrom or dvdrom.


In the end, your idea is based upon flawed misunderstandings of what cdrom technology is, and can achieve.
To say that

"For this reason it should be sensible to note that there is more to protecting a disc in this way than to cause a simple nuisance of backup"

is there? The whole point of copy protection is to prevent copying and piracy, so to protect a company's/individual's intellectual property and ensure they receive all royalties due. Nothing more.

Also

"We should also note that most modern 3D games are going online"

of course some are but not many. A serial code entered upon set-up is another layer to this protection which is verifed upon on-line connection. It is nothing to do with preventing copying of a cd, but another deterent to piracy.

In the end, you seem to miss the whole point of systems like safedisc. They are designed to prevent stage one of cd piracy. A serial or on-line verification is stage two. No single stage is 100% solid. That is why multiple layers are incorporated.
