Why would you need to do this?  You can copy the original as many times as you
like, you just can't copy the copy.

If you use a unit like the Meridian 518 or digital lens in the
recording chain (or any unit that strips superfluous code ) you can
defeat the SCMS.
There is a problem however , they also strip time code thus one has to
copy a CD track by track.

Once you have a non SCMS master , you can make a zillion copies of it
(as you can do with the original CD)

Im sure there are cheap anti-jitter units or digital processors that
do the same (look at pro audio , there might be products there that
strip SCMS at a reasonable price)

There is also a trick to fool the CD-r into not having to use
consumer-audio Cd-rs , let the machine read one , manually open the
drawer , slip a cheapy in , close the door , record and finalise.
This is also an option with the Pioneer machines , tho has to be
accomplished electrically and is not quite so simple

Basically on all machines , one has to find a way of opening the cd
drawer without the machine being aware of this.

However , one of the things the Cd-recorder does when reading the
"good" media is to do a few burn tests to get laser strength etc right
, although I have heard no complaints re using cheap Cd-rs in this
regard , it might be a problem with certain makes.

The good media should only be 3% more expensive than the cheap stuff ,
prices should drop radically when there is more demand for this
special media

SCMS is just not a consideration in PC-Based CD-R operations.

They said that about music CDs back in 1983 and look what happened!

When it comes to hi-fi any excuse to keep the prices up will do, in the UK
at least.

If Philips really wanted to oust Mini-Disc they should have brought out a
machine that uses computer blanks - OK keep the SCMS if they have to. But
did they - no of course not. We must use a special medium with a price
premium. Didn't they learn their lesson from DCC??

Quite right. And, no, you can't disable it in hardware. They thought of
that! The function is embedded in a chip, with no way to access it
externally.

No, they didn't, therefore they lost with their DCC, as well as
the V2000 format VCR (nobody remembers, perhaps :> ).

Philips may not be weak in technology, but they are weak in
marketing strategy.
They are simply not as clever as the Japanese. What a pity!

Yes, there are "SCMS Scrubbers" available. The DTI jitter remover by
Audio Alchemy (original version only) could do this, resulting in
a copy which was "SCMS 11" (one copy allowed), and with some simple
modifications, would produce copies which were "SCMS 00" unlimited
copies permitted).

However, unless you planned to actually distribute copies of copies,
why would you need anything more than "SCMS 11"?

Hi:

I found this article on the alt.audio.minidisc newsgroup.

From:
        david@frodo.com (dejansen)
 Subject:
        Consumer SCMS-stripper available

There is an SCMS-stripper being sold in some major Japanese
electronics chainstores for JPY16,800. It is a consumer product, not
some do-it-yourself kit, with two digital inputs and two digital
outputs. www.melting-pot.com is selling it for $249 plus S/H. Since I
live in Japan, I can provide it for $200 including shipping. E-mail me
if interested.

You can take a look at the unit at:

Devices exist that modify bit streams so that SCMS bits are changed. They are
not cheap and are not legal to use for the purpose of violating the copyright
law.

The music industry demanded the different media type (more expensive
CD-R's).

Hmm, Compact Cassette, Compact Disc (Joint Venture), DVD (JV)

I have seen advertisements of digital signal processors which remove the SCMS
bits. They come in handy as a convertor too, when your player has only 
optical output and the recorder only electrical input or vice versa.
If you're interested I can look 'm up, IIRC I saw them in some German
audio-magazine. They weren't exactly what you'd call cheap, something like 
$200 for the normal version and $400 for a more complex one which is needed
for Philips CDRW devices.

SCMS can be disabled.  Find an old original Audio Alchemy DTI .  It strips
the SCMS.  Audio Alchemy corrected the problem with later versions.
