I think this is the generic 'copy control' logo and if i remember correctly I have seen this logo on CDs containing CDS200 and DocData.

the logo you posted is the IFPI logo that says the CD contains copy control technology. there is no way to know what type of copy protection is used simply by looking at this logo. the good news is many people have been sharing information about corrupt CDs and it is now easier to know what corrupt formats different record labels use.

Here's the press release about the logo: http://www.ifpi.org/site-content/press/20020917.html

Here's a nice website about the topic: http://ukcdr.org/issues/cd/quick/

Note that those are corrupt audio CDs, not corrupt CDs per se, since they violate the audio CD standards. Although you could argue that deliberately placing invalid information on them makes them corrupt CDs in general.

Actually, if I recall correctly, there was actually one protection method which did not corrupt the CD... there was a method I heard about which is a data session with Autorun.inf, which runs a program that makes your computer incapable of reading the audio portion on only that individual CD. The audio itself was - or could have been, with this technology - left unharmed.

i think it's mediamax. i read an article a few months ago about how a princeton professor was able to rip a mediamax protected audio CD by simply pressing the shift key when the drive first reads the CD.

That sounds about right. With this type of copy protection method you don't actually have to press Shift if you have autorun disabled on that drive to begin with.
I believe it is often used in concert with data dropping/corruption protection methods: Ben Harper's Diamonds on the Inside appeared to use both mediamax and CDS.

Anyone looking to rip copy protected dicsc might be interested in this.
