Is There a fix for CD Pin-holes (CD Rot)
I have no experience with this program myself, but this receives mention in computer audio forums as an alternative to toast at a lower cost ($32.00.) Toast is on sale for $70 at present. I'd used Toast quite a bit with good results in the past. http://www.nticorp.com/NTI-Dragon-Burn-4.html |
Thanks everyone but I've found my answer. Regarding pinholes: Pinholes are caused by contaminates (dust particles usually) on the surface during metallization during manufacturing prior to sealing the edges. The metallization layer does not adhere at that given spot. Hence the appearance of a pinhole. However, despite appearing to be clear at that spot, there is still a lot of material around the pinhole that reflects the laser, combined with the error correction robustness, that 99+% of the time has no effect on sound or data reading. Pinholes are sealed in at manufacturing and do not or cannot grow. Nothing to worry about. It either plays from new or doesn't. You can see through, but they are just holes in the metal layer, not real holes. Excerpt from this forum... http://forums.stevehoffman.tv/threads/what-exactly-causes-pinholes-on-cds.637893/ Only two CDs wouldn't play probably due to pitting on the silver center ring (it sounded like the disk was spinning w/o reading). |
I'm going to try the CD shields offered by LAST ... https://thelastfactory.com/product/special-cd-dvd-cleaner-treatment-free-digi-last-cd-shields/ |

@elizabeth , all good comments. The info on the website states that the shields are a film that adheres to the CD label, no adhesives. It’s as thin as plastic wrap for food. I tried Herbies CD mat and it got stuck inside my CDP, so I’m very cautious about what slides into the tray/transport. In any event, I’d like to try the LAST CD cleaner instead of my homemade concoction. Also to your point, I’m leery of possibly ruining the label on a valuable early release CD. Good to hear that you’ve never had any peeling of the label, that is reassuring. And I have many CDs with the silver mould center, the first generation had them. BYW, on the first release collectors market they fetch a higher price. The only ones that won’t track have pitting (like corrosion) on the center area that is raised on the surface. Maybe it affects laser reflections? Or maybe they interfere with the clamping of the disc in the transport. I realise now the tracking errors have nothing to do with the pinholes. And as stated in the Hoffman thread, only certain pressing plants like PDO had the pinhole problem. I have quite a few early PDO CDs, and I’ve also noticed all my discs with pinholes come from Germany. I respect your views and experience in this hobby, so thanks. |
