'Bronzed' CD's (faulty by corrosion)
Posted by: naim_nymph on 28 September 2007
After spending a happy hour sampling music from the splendid classic selection on the hyperion site : ) I explored other pages on this excellent webb site that included the subject of 'bronzing'...
I now know why one of my disc's (purchased in 1994) plays okay from track 1 up to track 12 but on track 13 a crackle like an old worn LP sound will be heard in background, by track 15 the laser is skipping the disc and the final track 16 is unplayerble with the cdp transport going into convulsions...
The hyperion webb-site explains that the problem is the lacquer used to coat the discs not being resistant to the sulphur content of the paper booklets and inlays, this contact causes a chemical exchange and corrosion of the aluminium layer of the disc.
These troubled discs were manufactured from 1988-1993 and affects, (i guess a very small percentage), from the labels: ASV, Unicorn-Kanchana, Collins, Pearl, IMP, Virgin, Decca, Deutsche Grammophon, and Hyperion.
The very bronzed copy I have is on the (now defunct) Collins Classics label, (so no chance of a replacement)...
ANTONIO TEIXEIRA (1707-c1759)
Te Deum ~<>~ Orchestra of the Sixteen Harry Christophers @ 1992

Hi Gary,
It's good you got yours replaced in time, considering you had a pile of them!
I only have this one duff one, and it's my silly fault for not sending it back a few years ago when I first noticed something wrong...
One of my friends said that my copy is, The Twelve Harry, two crackers, one skipping and one dysfuctional Christopher!..
It's music from the Bronze Age!
(I won't go on)
Thank you for the Sixteen Contact info. I will ask them nicely about it but they're really not obliged to replace it so i'll probably end up buying one on their Coro Label.
kind regards ~
