Re: [ARSCLIST] CD Longevity

[Joe_Iraci@xxxxxxxxx]

Since the paper mentioned below was written, I did test other
phthalocyanine dye and gold metal layered discs. Below is a post I made to
AMIA-L in December.


In some cases you are not sure who actually manufacturers the discs, but
for what it is worth here is a list of gold metal-layered discs with
phthalocyanine dye that I have come across. Not sure if all are currently
available.

Brand - Kodak; Manufactured by Kodak (discontinued)
http://www.kodak.com/global/en/service/faqs/faq1632.shtml
Brand - MAM; Manufactured by MAM (formerly Mitsui)
http://www.mam-a.com/products/gold/archive.html
Brand - eFilm (Delkin); Manufactured by MAM
http://www.delkin.com/delkin_products_archival_gold.html
Brand - Apogee; Manufactured by ?
http://www.apogeedigital.com/products/cdr.php
Brand - Prodisc; Manufactured by Ritek
Brand - Quantegy; Manufactured by Mitsui
Brand - HHB; Manufactured by Mitsui

I have tested Kodak, MAM, eFilm, Prodisc, and Quantegy and all performed
very well in accelerated aging. All the disc brands manufactured by Mitsui
or MAM performed consistently. Also, I never had any coasters burning the
gold/gold discs to prepare them for experimentation.

Maybe I'm reading his tables wrong, but it seems as if the only gold
phthalocyanine dye CD-R tested was Kodak Gold 650MB.  Does anyone know
what other brands fall into this category?
