Digital Copy Prohibited (CP) in Jam 5. Does it do anything?

[Ant]

Hi, does the Digital Copy Prohibited (CP) option in Jam 5, or Jam 6, (or Toast 8 for that matter if it has it also), actualy work? I mean does it stop you or anyone else from copying a burned Audio CD? Is that what it is meant to do?

 

If so it doesent seem to work, as i can copy a burned audio CD that was recorded in Jam 5, and then on the same, or another computer copy it, using Toast 6.

 

So what is the CP check boxes actual purpose if it doesent stop you or anyone else copying? Here is what it says in the Jam 5 manual under Glossary;

 

"Digital Copy Prohibited (CP)

 

For each track on an audio CD, there is a setting that indicates whether copying the track is allowed once that track is burned to CD.

 

Note: The Digital Copy Prohibited bit was originally intended to prevent direct digital copying using DAT recorders."

 

Anyone?

 

Thanks,

thanks tsantee,

 

guess no audio music CD is safe now then, so there's no point in me worrying about trying to protect my original music, that i burn and distrubute on CD's. Oh well. it would only ever have kept an honest man from copying it anyway, as there are always lots of workarounds. at least now i know what that CP thing was for. Wonder if theve included it in Toast 8? Not that it has any use nowadays.

It only prevents copying with a DAT recorder so it won't prevent people from duplicating the CD or ripping its tracks just like you now can do with commercial audio CDs.

 

The audio CD format was created before there were CD drives in computers. As a result they didn't anticipate when creating the specs that people would want to see track names appear on the computer screen or that people will be able to digitally copy the tracks without use of a DAT recorder.

Thanks for your reply again tsantee. Sure Roxio dont pay you? lol. They should if they dont.

 

So does that mean any commercial audios CD can now be ripped? I remember something from a few years ago that some commercial audio CD's had something built into them that the user could only copy the CD once, then it wouldnt allow you to copy it again.

 

I thought maybe this CP thing in Jam might have been something like that, but wouldnt let you copy it even once. Seems i was wrong there then. Not quite sure why its there then in Jam. Why would anyone copy a CD to DAT, in the last 5 years anyway?

Roxio doesn't pay me but they've done a few nice things for me at times. I do this because there are few users of Roxio's Mac products who are active helping others here and I see my participation as a form of community service. Also, I learn a lot reading what others are trying to do and then trying that myself.

 

As far as I know any attempts to create copy-limited audio CDs quickly failed. Originally the music industry wanted everyone to shift from vinyl to CD because of much lower manufacturing cost. Everyone was copying their vinyl records to cassette for playback in their cars so it made sense that everyone could do the same with their audio CDs. But the industry didn't want people to make direct digital transfers. The only way to do that back then was DAT so a scheme was developed to prevent it. Because it is part of the official audio CD spec it is a feature in Jam. It seems pretty silly once the unforseen copying of CDs on computers became easy.
