I'm willing to buy recordable media (CD-R) that have a gold (not golden) dye, but don't know what brands are affordable.
The reason for this is very simple: I recently bought a Mercedes-Benz C-Class which has a Fujitsu DVD-ROM reader. Mercedes-Benz cars are extremely solid, but are known for their bad optical readers.
Before buying it, I had a VW Passat and I used the optical writer on my MacBook Pro (a HL-DT-ST, i.e. LG) to burn audio disks to be used on the onboard system. The Passat had no problem in reading them, and I always used the maximum allowed speed, mostly 48x or 32x in some cases.
Well, now the C-Class is uncapable of reading them correctly, not even one! Earlier tracks, such as 1-6, are often read correctly. Tracks starting from 7 to the last gets messed up in less than a minute: the CD starts to "jump", go back, go further, and so on. There are even some tracks where the disk stops playing for more than 30 seconds and then goes back again, and begins playing again. This can happen more than 1 time, even in the same track.
Initially, I thought the disks were scratched so the player had difficulty reading them, but this hypothesis was incorrect. The real reason behind this annoying issue is that there are write errors on the disk that the player cannot handle. The optical reader on the Passat was less sensitive to errors and could handle them, while this one is a very poor reader and can't do this.
So I did a test: I took the best writer I've ever had, my Plextor PX-800A, and started writing identical disks (disks with the same audio tracks) with the same media, but at different speeds. I tried the lowest allowed one (8x) and the highest (48x).
Surprisingly, the test ended with the lowest flaws while using the lowest speed. This contradicts the article in this forum that states low burn speeds with high speed media is no good. I still don't know why.
Even these disks are not handled perfectly and flaw, so my next attempt is to use high-quality media.
In the past, there were FUJIFILM CD-R's with a gold dye. Not golden: gold means made of pure gold (99.9995% purity), while golden refers to an electrolythic process of implementing very little gold.
They are really good: I have just one CD-R, burnt in 2001, of this kind. It is a 650-MB CD, but I can read it perfectly even with recent optical readers!
I don't care about money, at least now. Do you know any online shops where I can buy gold CD-R's ?
I found these disks from Nierle: http://www.nierle.com/s01.php?shopid=s01&cur=eur&sp=en&ag=1&pp=aa&bnr=12490 . They are Taiyo Yuden gold dye disks branded under JVC Advanced Media Europe. They cost a lot of money, circa 50 EUR for a 100pcs cakebox (while an "ordinary" media cakebox of 100pcs costs less than 20 EUR). But they seem to be real gold, not just plated, and they are also thermal-printable.
Are they affordable for you?
Thanks in advance!
