I just now decided to play the Herrmann-conducted Raff Symphony #5. I noticed the entire edge of the LABEL side of the disc has completely bronzed(The read side is perfect), but it plays perfectly. Have any of you who own any of those Unicorn Herrmann CDs had them become unplayable recently?

My copy of the same album still successfully ripped when I got it a couple years ago...I guess I should check it again! Yavar

I copied my Unicorn PSYCHO when it bronzed. I haven't tried playing it since, but I assume it is unplayable.

Just checked my copy of Psycho... absolutely no bronzing!

Had a moment of mild panic on opening the case, but I'm glad to say it's still playable.

yes it does happen pretty much with all the old original Unicorn CD's..I have Psycho, and in the classical department I have 3..W.S. Bennett's Piano concerto, Cipriani Potter's symphonies, and William Crotch's orchestral works. All bronzed, even if mostly around the edges. The only one that did not bronze is the Dimitri Tiomkin compilation conducted by sir David Willcocks (at least last time I checked..ironically, it's the only one i never play) I guess their manufacture of the surface was below to par, and the inside layer gets air/moisture. I have approx 1500 cd's, the oldest from the beginning of the cd era, and these are the only ones that bronzed. All that said, they all play fine: I cleaned them thoroughly, and then I sealed them with a cd cleaning/renovating oil they used to sell here in Italy, and further degradation did not happen. The Unicorn "new" cd's currently on sale on Amazon etc. are not cd's: they are blue-ish cd-r's produced by Wyastone in the UK, and as always, on a revealing stereo rig they exhibit inferior performance and sound (I tried A/B).

You should always rip a new CD to your preferred quality standard, and back up your files. Then your retail CD is just the backup of last resort. Another thing: if you play CDs in the car, they should be CDR copies. Dashboard players can swallow up a CD like a revoked ATM card, or the sun can heat your car interior to ridiculous temperatures.

Sorry to bump this, but I need your help with an issue: I recently bought a lot of cd scores and I found 3 releases that look like they are brozing. I attach here some pics so you can value them, as you can see the brozing has gone on both surfaces of the disc. REHEARSAL OF FORTUNE https://ibb.co/y0mkDT6 https://ibb.co/mbJmX4g DEAD POETS SOCIETY (take a look this one features some black spots, like dirt, on its surface, can you notice it?) https://ibb.co/9pddyq1 https://ibb.co/mFxZDrY Also, I got Bernard Herrmann's Wuthering Heights, and all 3 cds looks a bit brozing but not too much (the readible surface of all of them looks fine). I know there was some issue with the Unicorn-Kanchana releases. https://ibb.co/9cb43Q6 https://ibb.co/Y8t2jLQ https://ibb.co/BVG7cYd My questions: 1. Are these cds playable? Can I damage the cd player? 2. Is this brozing thing contagious? In that case, may I have these cds in quarentine, not near my cd collection? 3. To play these cds on a cd player, can "infect" the player and affect other cds when playable? Thanks in advance for your help with this trouble (sorry, I don't know how to attach the images on the post, you have to click to see them).

1. Are these cds playable? Can I damage the cd player? 2. Is this brozing thing contagious? In that case, may I have these cds in quarentine, not near my cd collection? 3. To play these cds on a cd player, can "infect" the player and affect other cds when playable? I don't see how you can damage the player. Bronzing isn't a virus-like thing that is transmissible from CDs to CDs, it's simply an oxidization of the playing layer of the disc due to perished seals at the edge of the disc. The CD player does not touch the bronzed surface. It simply shines a laser light through the transparent protective layer and reads the reflected light. If the bronzing has rendered the disc unplayable, all that will happen is the disc won't play. Cheers

My original of CASSANDRA CROSSING bronzed but was still playable when I last tried it. If someone wants to see how far CD bronzing can go, here are my two italian RCA editions of THE CASSANDRA CROSSING as an evidence (RCA Original Cast OST102 in both case). Oh, dear. I better try mine soon.
