BMG Backs Down Over Copy-Protected CD

An anonymous submitter sends in: "As reported by The Register, on the 5th of November, BMG released the UK's first copy-protected CD (more information on Eurorights and Fat Chuck's). It uses Cactus Data Shield by Midbar Tech, which aims to prevent CD to CD or digital CD to Minidisc copying, along with converting to MP3, but may have other bad side effects." The submitter continues: "There were complaints from fans and many took their CDs back or wrote to the record company and record shops. Their hard work seems to have paid off since Virgin Megastores has responded to a complaint from one of their customers and said that BMG has set up a helpline to allow people who bought the corrupt version, to exchange it for a real one. Virgin and HMV will also be bringing in new stock of uncorrupted CDs. The message was originally posted to the Official Natalie Imbruglia Bulletin Board (free registration required) in the "White Lies" and "Lillies vs Cactus" threads, but several threads containing complaints against Cactus Data Shield have been deleted so the email has been mirrored on the Free-sklyarov-uk mailing list. This is very good news, but more work needs to be done. Hopefully with pressure from the public other retailers will follow Virgin's example. Also record companies need to be made clear that selling copy protected CDs, that infringe on the public's rights, is not acceptable. The battle isn't over until no new CDs are shipped in these formats so if you find a CD that is copy-protected then report it on Eurorights for the UK, or Fat Chucks for elsewhere, take it back to the shop, and let them, and the record company know your feelings on the issue."

This would not happen in 2003 in Europe

With the EUCD (European Union Copyright Directive), that is starting the process of getting incorporated into national laws, BMG would have the law on it's side and copying CDs with this kind of protection would be a crime, even if it was under a "fair use" clause. This is the main problem with this law, for the first time any company can restrict how you use its products. Until now copyright law only affected copying, distributing and modifying the product.

In the USA the won't probably do a recall because all this is legal under the DMCA. Providing "fair use" became optional.

Midbars patent application for Cactus Data Shield

[sjmurdoch]

Even though Midbar deny there is any chance of Cactus Data Shield damageing equipment, you may be interested to see an extract from Midbars patent application for the technology.

Of particular interest is the section:
During duplication the CD encoding circuitry merely sets the P-channel=0 while recording to the data are, and therefore the P-channel setting of portion 60 is ignored. Thus, during playback, the substituted audio data portion 58 is provided to the digital-to-analog converter as normal data, resulting in audio distortion and potentially damaging the output circuitry. (emphasis mine).

They also don't seem to be as confident about audio quality as I would have hoped:
Thus, the substitute audio data portion 58 of FIG. 4B is ignored, and instead an interpolation, substantially equivalent to the original portion 50 of FIG. 4A, is output, thus resulting in little or no net difference in audio quality between the corresponding track port 44 and 52 of FIGS. 4A and 4B (again empahasis mine).

If I buy music, I want the CD to be as close as possible to the real thing, not with any noise added.
