Re:The "copy protection" is fundametally flawed (Score:3)
I think that the DMCA requires that for a circumvention device to be illegal its primary purpose must be circumvention. There already exists a lot of software out there, such as cdparanoia [xiph.org], which was written to interpolate out the errors on CDs and I believe that their primary use has been to do this on normal (i.e., not brain-damaged) CDs. I doubt that the DMCA would make such software illegal as it serves a legitimate purpose in its primary use.
This raises an interesting point, though - wouldn't the music labels intentionally introducing errors onto CDs actually encourage copying? If I purchased a CD with errors on it I would use something like cdparanoia to correct the errors and then save the results on a CD-R as the results would be more resistant to actual errors that arise from scratches and physical jostling while playing in the future (this assumes that I liked the music enough to do this - my first inclination would be to return it for a refund). I would not have needed to make the copy had the CD been normal because the error correction capabilities would have not been degraded already.

Some [expletive deleted] broke into my car last fall and made off with about $600 worth of stereo equipment and about $600 worth of CDs (don't believe it when they tell you a detachable faceplate is protection against theft). Every single one of my favorite albums was stolen (and I stil haven't replaced most of them). The morning I discovered this, I swore I'd never keep an original CD in the car again.
BUT WAIT!! If the theif makes off with a copy of a legally-purchased CD, YOU are now responsible for illegal distribution! Horrors! The record company lost out on another sale because YOU made a copy!

I'm not saying it's illegal to copy music, just that the AHRA does *not* give de-facto permission for people to copy music, even it it appears to at first glance.
There is a difference between something being 'not illegal' and being 'a right'.
ALl the act says is that you cannot be prosecuted for using a compliant device to copy some music; it does not say you have a non-infringable right to copy the music. Nothing in the act prevents them from making it technically difficult for you to copy music.

is it illegal for me to make copies (or partial copies) of CD's that i own for my own personal use?
No, according to the Home Recording Act of 1992, it's perfectly legal for you to make personal copies of CDs you own.
However, that same Act does NOT say that the record companies can't try to stop you from making such copies (through content control mechanisms) -- just that they can't sue you if you suceed. Of course, if you try to bypass these content control mechanisms, you're most likely in violation of the DMCA.
All of this may be moot as far as using your computer as a jukebox, however, since the courts still haven't decided whether or not a computer should be classified as a digital recording device (if it were ruled not to be so, it wouldn't be covered under the Home Recording Act).

There are no real difficulties in writing code to read over a ripped CD image, and do the interpolation in software.
I just hope that solutions to this come out soon (and, in particular, for Windows and not just linux), so that the record companies realise how pointless the scheme is and stop writing trash all over our fairly purchased music!

If enough individuals do this, the stores will be forced to spend their resources (time and money) with the returns (which take 2-3 times longer than a purchase).
If it happens enough, the stores will in turn be forced to work with the record labels to stem the flow of returns.

Re:Great testing method (Score:4)
I should point out that they did first pass samples by people who listen to music for a living, so called "golden ears," who couldn't detect it either.
Apparently the main defense is take out tiny portions of the music. Small enough that CD player error correction will accomodate, but a direct data transfer will turn into bursts of gibberish.
This secret release is their way of making sure that the CDs aren't returned simply because people know about the copy protection.
I don't agree with what they're doing. Not because I think they can't legally do it (of course they can,) but rather it's a problem with what it represents. They're actually changing the music as part of the protection. To paraphrase a critic from another article, it would like cutting gashes in priceless paintings to keep them from being stolen.
Re:Creation of custom CD Ripping hardware (Score:3)
This raises the question: It is illegal under the DMCA to crack encryption no matter how trivial, but it is legal to make coppies of music for personal use. Does this mean that I would be within my rights if I were to develop a mechanism to copy and store streamed music from subscription music services such as are being developed now? - this assuming I could play the music that I hace coppied off of the streaming service...
This is why the DMCA is bad, under the "Fair Use" laws you have the right to make copies of music you have purchased for personal use. However, under the DMCA, if the music is encrypted, any attempt to break the code is illegal, even if it is for "Fair Use" purposes. Further any tool you use to break the code is also illegal even if it also has non-infringing uses, which might otherwise be protected under "Fair Use". This is the reason why it is thought the DMCA is not about copy protection, but control, greed, corruption and power.

It's a basic fact of human psychology that people hate people who they see as more fortunate as them and love making excuses for it. So, if you're rich, no one will like you.
So you say, I choose to think otherwise. I am often surprised by the number of people around me who admire rich, successful people. Frequently I don't share their regard, less often I do. I base my opinion of these people on their actions, not their personal wealth. I would actually assertthat today's society breeds people who do admire personal success over most other traits. More is the pity.
If you're rich, everyone will assume you got there by lying, stealing, being dishonest, etc. (that rationalizes why they, themselves are not rich).
Many rich people really did get that way by dishonesty. If you don't see that from everything that goes on around you, why, perhaps you are blind? Yes, there are also some rich, successful people who have got to where they are whilst maintaining principles and standards. But they truly are in the minority.
That's also the reason why every loser on Slashdot hates all "evil corporations". Most people - especially the incompetent - simply cannot accept the success of others as being a result of their competency.
But life is not just about competency. It's also about what you use that competency to accomplish. If what you accomplish is to make the world a worse place, then that is a bad thing, even if you did it very competently and made lots of money doing it. This is the bit you seem to miss.
So you go ahead and defend your theft by pretending the music companies are dishonest and greedy while they'll go ahead and try to stop themselves from being robbed.
This story, and the threads I have read so far, art not about theft and robbery, but exploitation of the masses by the minority.
Some Copy protection Details (Score:5)
Agreed.
The technology takes advantadge of the error correcting technology built into every audio CD. This technology is what allows the CD to play well even with hundreds of minor scratches. I think that the error correction will try to compensate for loss of data up to a tenth of a second or something like that. What they do is they put hundreds of minor glitches that are able to be corrected for by the technology. The error correction technology works really well, and is no way even close to being similar to a wave file.
If I recall correctly, compact discs use a version called cross-interleaved Reed-Solomon code, or CIRC. The basic level of error correction provided for Audio CD is one uncorrectable bit out of every 10^9. CD-ROM provides additional protection for data (ECC/EDC ) reducing the error rate to one bit in 10^13 For those interested, there is this detailed description [ffii.org], along with this basic introduction [siam.org].
The coding system is based on groups of bits--such as bytes--rather than individual 0s and 1s. That feature makes Reed-Solomon codes particularly good at dealing with "bursts" of errors: Six consecutive bit errors, for example, can affect at most two bytes. Thus, even a double-error-correction version of a Reed-Solomon code can provide a comfortable safety factor. Current implementations of Reed-Solomon codes in CD technology are able to cope with error bursts as long as 4000 consecutive bits.
Thus it is possible to put in a couple hundred bytes of junk data every second or that would be the basis of the copy protection, all without compromising audio quality.
That said, I can record any sound playing through my computer with the software I have. The Audio Quality will be very good, then I can burn direct to CD, or convert to MP3, or whatever. Of course, all that I use this for are the music tapes I have from when I used to record certain local bands in clubs professionally.

True enough, but we must remain vigilant in our resistance to ridiculous laws that attempt an end-run around The Constitution. Guns are not bad things when used properly (hunting, killing rabid animals in a rural or suburban setting, protection from violent thieves and crack addicts, etc.), and yet some people claim that the commoner shouldn't have them because they *could* do harm with them. The same thing would apply to CDParanoia eventually, which I find to be ridiculous.

The favoured method, IIRC, was to use a duplication method called parameter copying. People worked out what they needed to do to get around the specific method employed on their favourite game, and then wrote a little plug-in which the copier could use to modify its copying methods for that specific disk.
As a side effect, interestingly enough, those errors often used to cause the 1541 disk drives a lot of grief. Depending on the error, the 1541 would get so confused that it would try to realign the read head by forcibly moving to the outside rail and banging very rapidly against the rail, causing a loud chattering sound. You could even get a program which would write a small loader program and lots of errors to a blank disk, causing the disk drive to play tunes by going through this realignment procedure and knocking the read head against the realignment rail at different speeds. It did this for all of 10 minutes until your 1541 died a noisy death...
