A square wave is easily maintained through even a cheap receiver and amp. 
It's the speakers which have trouble moving instantaneously from + to -.

There have been "conventional" recordings which were infamous for 
containing square waves and having equipment-damaging potential.
Usually these would be recordings of the 1812 Overture with the 
cannons driven into clipping in the recording.
 
However, the trick in the Cactus system is the claim that the 
CD data is manipulated so that the original disc plays musically
and safely, while a copy produces noise, and could be manipulated 
to produce a square wave.

That really doesn't make sense - it's all digital stuff - just 576 byte
blocks of data -- either you copy it, or you don't -- a CD-R is going to
see just the same bits on the disk that a CD player will, baring weird
chemistry or physics trying to play "tricks" with different kinds of
lasers.

  Marcus raises the obvious objection.  Either there's something more
  to this scheme than explained in the press reports or Cactus is some
  kind of pseudo-technological scam intended to soak panic-stricken
  recording execs..

The theory is that an audio CD player will realize that the data makes no
sense, and fix the obvious errors.  Normally such errors would be the result
of corrupted data; ie a scratch or other physical damage.  A CD data read
would read the data as-is, then lay it down on a new CD as good data.  But
yeah, why wouldn't the audio read of the copy fix the same problem?  Maybe
there's a checksum involved which aids the fixing of the bad data on the
original?

Yes, but whatever's happening is *probably* something that CD-RW
software can do just as well.  I'm not sure there's any checksum (or
that there isn't)--I do know though that when used to store data
(CD-Rom) only 512 bytes of data are stored in the 576 bytes -- the
remaining 64 bytes of data are used to store (I think) ECC data to
repair any minor read errors -- this isn't done for audio because a
1-bit error in audio data is typically not audible.  That suggests to me
that there isn't any checksum on the audio data.

It probably has something to do with the underlying subcode tracks on the CD
that audio players use but CD-ROM drives can't copy, but that's just a
guess.  I remember that this was why Playstation CDs couldn't be copied and
the copies run in an unmodified Playstation -- the boot code for the
Playstation was hidden in those subcodes.  Supposedly you can fit about 2
megabytes in there, spread across the entire disc.

At least some CD-RW players are (as best I can tell) capable of copying
all the subcode data as well.  Any CD-RW player has to be capable of
copying the P and Q subcodes - I believe it's integral to how it knows
the difference between data & audio, and other important stuff.  Some
common tricks used for copyprotection include a bad table of contents
block (apparently audio players don't need to use it...?), and
scattering bad sectors or data on the disk.  The bad sectors can cause
data under-runs if you're copying from CD to CD, but I don't see how
those can break things if you use the HD as a buffer.  I don't entirely
understand how a bad table of contents can break things, but that's the
claim.  It sounds to me like something that could at least in theory be
programmed around, if you were "clever".

"Putting the Pieces Together: An End To End Solution for Protecting Music"
A music business fantasy about how our ability to copy CDs and music 
files will be restricted, and how we'll all put up with it just fine.
Notice the handwaving where the writer assumes that no one will want to 
put up with second-generation music files which have been passed through 
the analog domain to strip out all copy restrictions...

The MusicDish article is amusing.  Serious math/logic errors in the first
paragraph.  I really doubt that 30 million people are getting their music via
online sharing, especially not for one specific album.

Basically, a company called Intertrust will provide the Digital Rights
Management (DRM) format for DataPlay-enabled devices. The DataPlay discs have
yet to hit the market, but are purported to be small and portable, about the
size of a quarter.

  I'm not sure I want my music to be recorded on media "the size of a quarter"
  if the record companies are going to pesist in charging nearly twenty
  dollars for new recordings.

Gee. You know, that DataPlay device sounds an awful lot like a minidisc

Considering that these players cost four times what a low-end CD player does
now, and that the discs aren't likely to sound any better than CDs (maybe
even worse, since they're compressed), this is going to be a hard sell.

I'd be afraid I would lose them too easily being the size of a quarter. 
It would be handier to carry around and seemingly light.. Feh I have 
enough trouble keeping track of my minidiscs. :)

"6 CDs a Year, or, Consumers and record labels are at war."
 
Nothing too original here, but it's a nice essay.  It does point out 
that in the conventional economics models, the progress of technology
is supposed to lower prices so that consumers can get more bang 
for their bucks, but the record industry is using its oligopoly power
as best they can to prevent this from happening.

I was thinking about this yesterday after I talked to Drew at work -- he went
to Borders to buy the "O Brother Where art Thou?" and "Songcatcher"
soundtracks. And he said that the clerks were so unhelpful and so unclued that
he gave up and went to Best Buy. (Which is a comment on the staffing at teh
downtown Borders going downhill... in and of itself). But then I was thinking
that a major reason for people not buying records is the problem of where to
get them -- I know that a lot of people do buy on line, but most of the people
I know don't as a rule. Music for a lot of people is something they still want
to look at, ponder, all that -- and without some record stores that cater to
that need, a lot of people will stop buying. And of course the cost factor
doesn't help. Just some random musings.

That was certainly true when I was in Chicago.  There were two decent record
stores in Hyde Park, but neither of them were very well staffed, and I
wasn't familiar enough with them to just blunder around the place on my own,
the way I do in Encore or Wazoo.  I ended up buying two CDs the whole time
I was in Chicago, both of which I was ordered by friends to go out and buy
This Instant.

An anonymous source says that the Department of Justice antitrust probe
of the major labels and their online music ventures, which was revealed
this week, has been ongoing for months.
 
  'The source said that the probe was
   initiated out of the DOJ's antitrust
   division in response to "disillusionment
   with the business practices of the record
   companies" from "multiple parties at every level of the music
   value chain," including recording artists, record stores, and
   online music services.'

http://www.usatoday.com/life/cyber/tech/review/2001-08-15-korea-napster.htm

Two South Korean brothers, both educated at American universities, are 
facing criminal prosecution for copyright violations.  They wrote a 
Korean-language Gnutella-style file sharing program called 
"Soribada," which translates as "Sea of Sound;" they felt Korea
deserved its own file-sharing system.   Potential penalties include
up to five years in prison and fines of $38,500.
 
Soribada does not user a Napster-style central service; it is clear
they are being prosecuted as the authors of the program, not for 
operating it.

        I'm not into the tech, but with the lasers to read disks now
at a higher frequency, they can find the 1's and 0's closer together;
putting the same digital information is a smaller space.
        Also, wasn't the standard for the CD set up to be 4 discreet
audio channells, room for text and/or graphics, etc?  A new standard
could ignore those things the public rarely sees.
        Then again, DAT (digital audio tape) was tried as a new
pre-recorded format.  It failed.  The Mini-Disc (MD) was tried as
a pre-recorded format.  It, too failed to find a consumer market.

"How Radiohead took America by stealth," by the UK paper The Guardian.
 
Radiohead's recent success, according to this article, relied 
on internet fan communication.  The record company mostly stayed out 
of the way.

> Most controversially, Radiohead and
> Capitol encouraged fans to copy and
> circulate free bootlegs of Kid A (((the next-to-last CD))) in its
> entirety across their own sites three
> weeks in advance of the album's official
> release, upon which it went straight to
> number one with no radio airplay, no video
> and no hit single. 

The article does raise the question: so what does Radiohead need 
Capitol Records for?  Why doesn't the band take over its own 
relationships with the fans?

The New York Times has a collection of pieces today.  Besides the music
stories referenced below there are a few more on the impact of digital
technology on other arts.

   is a puff piece on Hilary Rosen, the head of the Recording Industry
   Association of America.
 
http://www.nytimes.com/2001/08/20/arts/20ARTS.html
   "Why Just Listen to Pop When You Can Mix Your Own?"
   Discusses the rise of web sites where fans share their amateur
   remixes of work by their favorite artists, with a focus on Bjork.
 
http://www.nytimes.com/2001/08/20/arts/music/20CEED.html
   Popular music critic Neil Strauss writes about two weeks spent 
   listening only to music found on the net: one week before the 
   crushing of Napster file sharing, and one week recently.
   This article will mostly be of interest to geezers and trailing-edge
   folks like me.

In the post-Napster world of Summer 2001, Strauss seems to have found 
happiness with a mix of Aimster, IRC chat channels, and KaZaa.
