(The voltage coming out of a wall socket
in Luxembourg ain't the same as that going into a toaster in Truth or
Consequences, New Mexico. Though this be common knowledge held by W.A.C.O.
and the majority of children on this blessed earth, the viability of
non-indigenous CD's in Australian players should be an item of concern
to travellers who like to share a tune with a newfound "mate"...)
I am coming to Australia for a 3 year stay. Should I bring my CD's to
play on Aussie equipment?
You will need an American to Australian converter
device. This is usually hard wired into the CD player by a reputable
Australian tech. They are all familiar with the device. Just pop into
any CD store and request the phone # of the nearest CD converter tech.
Its usually only around $30 and you will not even know it had been
done. You will be able to play not only US cds, and Australian, but
as a bonus, European ones too! CAution-do not try to play bootled
CDs after the conversion,you will ruin the cd player
From Adrian Rose
Sorry about that last post-to play your US cds in Australia,they merely
need to be passed thru a strong magnetic or x-ray field,such as you
get at Customs.Be sure to pass each one thru separately,as bulk passage
may leave the ones in the middle unplayable in Oz.
From Mark A. Gray
Well...this may gave worked for you, but I found that the only way
the get 'em playing was to smear the shiny side with a very thin layer
of vegemite. 'Course this makes the inside of your CD player rather
sticky, so make sure you have lots of tissues.
From Hans Andersen
Don't listen to them. To play American CDs in Australian CD players,
you will need to regroove them. This is because Australian CDs have
a different track-width (i.e. 10 ums instead of 5 ums). To do this
you will need to buy some fine-grade sandpaper. Try to find some with
a grain size of between 8 and 12 ums (micrometers for non-technical
people). Put a piece of the sandpaper on a table with the rough side
up. Now put your CD on the sandpaper and turn it slowly in a clockwise
direction, pushing down hard. Oiua la (spit) - now you have Australian
standard CDs. Good luck and I hope you enjoy Australia.
From Michael Jennings
No. That is completely wrong. Australian CDs are exactly the same
as American ones except for the fact that the 'groove' goes in the
opposite direction. That is whereas an American groove goes inwards
as you go clockwise an Australian groove goes inwards as you go anti-clockwise.
This is because Australian cars drive on the left and American cars
drive on the right. If the groove direction was not reversed there
would be parity problems with car CD players. Unfortunately, this
means that you cannot play an American CD on Australian equipment.
From Stephen P. Guthrie
You smartarse. Obviously this is nothing to do with the side of the
road cars drive on. Do you seriously expect anyone to swallow that?
Anyone with a brain knows that it's related to which direction water
goes down the plughole in the Southern hemisphere. In other words
in the US the cd rotates in a clockwise direction. In Australia it
rotates anticlockwise. Of course this is also true if you play your
cds in South America for example. This is actually quite neat because
if you play your beatles cds in the Southern hemisphere you hear all
this neat 'backwards masking' stuff about Paul being dead and taking
marijuana. Also I heard that you hear all sorts of satanic stuff in
other rock albums, but I'm not a fan myself. My question: has anyone
done any experimets about playing cds at the equator or at the notrh
pole? At the equator do your cds stop playing altogether. What about
in a reduced gravity environment, like in a free faling elevator?
From Tye Leslie Sanders You're all a bunch
of liars!!!! In Australia the initials C.D. stand for Completely Dislexic
which means that the bits are scattered at random all over the disc.
All Australian C.D. players are programmed to randomly search over
the disc to find the right bit to play next. It is very unlikley that
it could cope with a disc where all the bits were in order. I would
advise you to record your discs onto Hi-Fi video tape and connect
an Australian VCR to a stereo system. Australian and American VCRs
are definitely compatible
From Mark A. Gray
I can't speak for a reduced gravity environment, but I can speak for
the equator. It is interesting that you should bring it up, since
many CD's simply do not spin at the equator (or near it actually).
In Singapore (for instance) they had to ban a whole bunch of CDs or
have them altered so that they would play correctly ('corse if they
had a bit of vegemite their problems would be solved). Video tapes
and books(!) seem to suffer the same fate their. Why don't books work
properly at the equator? And I have another question: Short of smearing
every page with vegemite, how do you get a northern hemisphere book
to work properly in the southern hemisphere? (I'll be bringing some
books home with me when I leave here, so I need to know). Thanks in
From Tye Leslie Sanders
Re-your querey on playing CDs in reduced gravity, it is not widely
known that on the last Space Shuttle mission it was decided to test
the effects of playing a compact disc in zero gravity with disasterous
results. When the disc was played, instead of the disc spinning, the
entire vehicle began to spin while the disc remained motionless, turning
the entire spacecraft into a giant centrifuge, nearly crushing theastronauts
to death before the commander was able to crawl to the machine and
press the stop button.
It has been suggested by some at NASA (who
have now been dismissed for discussing government secrets) that a
compact disc was the cause of the destruction of the Space Shuttle
Challenger in 1985. As you may recall, this was the first mission
to take a civillian into space. To ease her mind during take-off it
was decided to simulate an environment of Earth similar to that of
take-off pressure so they decided to play a CD of elevator music to
give her the feeling that she was riding up in the lift at her local
shopping centre. The craft could not cope with the enormous centrifugal
force generated by the spinning disc and broke apart approximately
1 minute after take-off. It was decided to cover up their gross negligence
by saying that the o-ring seals in the booster rockets were faulty.
All this is absolutely true or my name is not Ronald Reagan.
From Bob Hiltner
This is a complete load of crap, and probably a troll. The 'Borealis
Effect' (or 'Australis' in the sourthern hemisphere) could in no way
overcome the power of the motor in a cd player. Besides, the 'groove'
went out in the 60's (70's?). I'm no electrical engineer, but I'm
guessing that any backward playing effect is due to the 220v power
conversion (which would show up on euro equipment as well) or the
reverse polarity down under. As for the gravity-free environment,
who gives a shi*t? I think the astronauts have their hands full anyway,
and probably can get good FM reception from any station on earth if
they need music to dance by... Some people are so clueless!
From Joe Chew
Since the Earth rotates in the opposite direction in the Southern
Hemisphere, the AC power there is supplied 180 degrees out of phase
with ours. Thus your CD should work just fine, although some audio
purists insist on a motor- generator set to supply "American" electricity
and then determine the phasing themselves.
From Orion Auld
At the equator, the cd's stop rotating, so the cd players there must
rotate the laser about the stationary cd. The units are very expensive.
By contrast, at the north pole, cd players are very cheap. This is
because neither the laser or the cd require a motor to provide rotational
energy; the cd is placed precisely on the north pole, tied to the
firmament so that it doesn't spin , while the laser is fixed to the
earth, slightly off-center, and the earth provides the rotation. What
about in a reduced gravity environment, like in a free faling elevator?
The cd's are virtually weightless, so they can be very massive and
yet consumers will have little difficulty operating them. I hope that
answers your question.
From Jim Gunson
I'm glad you brought this up. The variation of the Coriolis force
with latitude (zero at equator, max at north pole, min at south pole),
gives rise to the so-called beta effect. Basically what happens is
that when a clockwise-spinning object, in the northern hemisphere,
moves north it speeds up, when it moves southe it slows down. I've
conducted experiments whilst driving my car here in Boston: if I head
north on route 93 at 75 mph with Kylie's "Locomotion" on the CD player,
the pitch of her voice goes higher, but you have to be going pretty
fast to notice this. Heading west or east this doesn't happen. To
the original poster, if you do find you're having trouble with the
Coriolis force adversely affecting your US cd's in australia, try
turning the cd player upside-down.
From Adrian Rose
No, no, no...................please dont confuse the Coriols effect
with the Doppler effect-the two are quite unrelated, and the Doppler
effect is ALMOST unnoticeable, when playing out-of-area CDs,or even
records. The effect was most noticeable on 78's,but that's now academic.
BTW,I am able to offer the conversion at only 75cents (us),if done
in bulk. E-mail for quotes.
No if regrooved in the N Hemisphere the must be spun counterclockwise,
remember Aussie turntables etc spin the opposite way, ps Marmite works
as well as Vegimite. From Armadillo No, American compact discs will
only work if you drive on the right-hand side of the road. But I wouldn't
expect an aol.com user to know these things.
