Then I guess your statement "Slower speed media have more gold in its dye" was simply a typo.
Han wrote:You could say I've used a more common phrase. The other day I was reading an article describing the whole procedure of making high speed CDR media and was quite surprised that these media have much thiner dye. Under that impression I wrote that slower speed media have more gold in its dye. - If you look closer, you'll indeed see that these discs are more transparent...
Han wrote:Sorry for not being more precise. When I say dye, I actually mean it, and when I say reflective layer, I mean that too. I should corroborate my observations also with thinner reflective layer.
Han wrote:It bothers me quite a bit that companies, in order to keep the minimal profit, are reducing both - thickness of dye and reflective layer.
The article is in our local monthly paper. I guess I'd have to translate it for you to understand it...
cfitz wrote:They don't have an online version, I suppose, since it is a small local paper. But then again they probably got the article from another source, since it is a small local paper. Any chance they listed the prime source?
cfitz wrote:By the way, when you say translate, do you mean to electronic format or to English? If it is the latter, I wasn't aware you spoke another language.

Do they offer tours? That would be interesting to see.

Han wrote:I'm trying my best, thanks. I learnt English in primary and secondary school (8 years total). I also took private German lessons and then learnt it in secondary school as secondary foreign language. But I didn't like it much, so I'm quite embarrassed I can't read/write it with confidence.

One thing I noticed is that I cannot see the color change that would normally be associated with other non-black CDR's.
