1264.0. "Gold disc hype: True or Bull?" by MPGS::MARTEL () Tue Jul 12 1988 02:05

    
        Several times since last Christmas, I've seen gold CD's in the 
    store that claim to be superior to the regular aluminum plated ones.
    Not only are they supposed to sound better, but *LAST LONGER* !!!
    
        First, since an ordinary CD is not supposed to wear out, how much
    longer can a gold CD last?  And should I care?  Especially, at nearly
    $26 a whack???
    
        Why should these sound any better?  I don't think I can hear an
    error corrected dropout anyway.  And besides, they dont occur that 
    often, do they?
    
        So,,, are these claims exaggerated to sell pretty discs for 
    more money?

1264.1Superior technology or Hype?COOKIE::ROLLOWDo the Left thing.Tue Jul 12 1988 11:347
	Mobile Fidelity has generally done a good job of getting
	the better quality master tapes and transfering them to
	vinal or CD.  I'm not familiar with their cassettes.  The
	gold may or may not help the media quality and in turn the
	sound, but I would expect a superior remastering job for
	$26.00.  I would also expect better remastering of the $26.00
	version of Crime of the Century than the $16.00 version.

    Depends....do you use gold speaker wire, with gold jacks ??
    Do you have a "goldtone" Marantz setup. I really doubt the validity
    of any statement alluding to a "better sound" from gold discs. Will
    they last longer ??  Probably, but I have the feeling that once
    again, the recording industry may be pulling a fast one on us. Heck,
    if I keep my discs in a normal environment, such as a living room
    or den or if I don't leave them lying out, or use them for coasters,
    I'd think they'd last a lifetime (however long that is). I've got
    reel to reel tapes that I'd recorded 16 years ago, whose sound quality
    are fine....no more dropouts now than the 1st time I played them
    back. When I recorded them, the word was that they'd be just about
    blank inside 8 to 9 years. I've got a 1953 lp that sounds as good
    today (better, because of the playback equipment I now use) as it
    did in '53. Bigger, better, best.....you get what you can afford
    and take your chances. Once you get to the point where you can break
    neighbors windows or rattle 20 other cars at a stoplight....where
    does a person go ??

    I thought all cd's were written '1's and '0's?
    
    Whats the difference between reading a '1' on a gold cd and a '1'
    on an aluminum cd?
    
    If I've got digital recording (on cd's) all wrong, will someone please 
    inform me?
    
    Thanks,

    Digital Audio did a test on the Mobile Fidelity gold discs and did
    not measure any significant differences between them and regular
    discs.  MFSL claims a lower error rate with the gold discs, but
    all discs are supposed to meet a maximum correctable error rate,
    so there shouldn't be a problem here.  The only advantage I see
    is that the gold is less prone to oxidation than the aluminum.

1264.6There is a possibility that gold is better.SMURF::BINDERA complicated and secret quotidian existenceWed Jul 27 1988 11:4712
If, as has been bruited in the press recently, the paint used to label a 
disc will slowly eat its way through the lacquer and then oxidize the 
metal, gold is clearly superior to aluminum, because a gold disc will 
not suffer this destruction.

If, on the other hand, this problem is a lot of bull, then gold has no 
inherent superiority over aluminum.  In fact, it has the potential to be 
inferior in terms of visibility to the playback phototransistor, because
its reflectance spectrum is limited compared with that of aluminum.  But
I don't really think this is a problem.

    Gold reflects infrared slightly better than aluminum does; that's
    why spacecraft typically have gold-plated (rather than aluminized)
    thermal shields.
    
    If you lend me a gold brick and an aluminum fry pan, I will gladly
    make the appropriate measurements.... :-)
