Encrypted audio CD's
 
I found an import Coldplay CD-single yesterday at Border's that has a live version of "In My Place" and an acoustic version of "Yellow" that I was going to add to a CD-R I was going to burn. Well, only once could I get it to play and it skipped massively. I tried to copy it but the D drive couldn't find the tracks to point and drag for burning to a blank CD. I remember reading awhile back that a few companies started to encode (somehow) CD's so that one, computers couldn't read them and two, rendering them uncopyable. In this instance did I stumble across such a disc?

Maybe. You could always try the pen trick just to find out.

But you should erase the ink afterwards, I wouldn't want to encourage violation of copy protection or anything.

how does that work?

You might want to look it up. I believe it is drawing a ring around the outside of the CD to cover up the "data" that makes the computer think it's a data CD instead of a music one. How far in, I don't know. I guess until it works.

Since CDs are written from the inside to the outside you wouldn't be covering up any music unless the thing was cram-packed, like 74+ minutes.

Some of my recent CD purchases had the same problem. X is right, just make a few single-layers around the outer edge. Remember to use a felt-tip pen though.

Since this borders on copyright infringement, I'll stop my tutorial here.

Wow that sucks. I wonder how this will affect my NetMD if I come across an encypted audio CD.

No, it doesn't border on copyright infringement. The labels are violating the specifcations for audio CDs (Red Book) and are using deceptive trade practices; the music discs they are selling are not CDs, which they say they are. A CD can be played in any CD player, CD-ROM, etc. with no problem. By keeping it from playing in certain players, they are violating the Red Book spec.

You're just fixing it.

It violates the DMCA since you're circumventing copy protection. The felttip marker is also now illegal since its a circumvention device.

But the copyright protection violates laws because they market the audio discs as CDs, which they are not.
