I have read all of the above. I respect CDRInfo authors. Like I do those, who sweat over the details here at CDFreaks and at CDRLabs. However, I think that several people here and elsewhere have quite reasonably shown that we don’t have a trustworthy universal disc quality scanning device at our disposal yet. Most mods here do understand this fact and most likely knew it before I did, even if for different reasons.
I have also read ‘Digital Audio Technology’ (Focal Press, 2001) and ‘DVD Players and Drives’ (Newnes, 2003) plus a couple years worth of ODS Magazine dvd tech articles.
Not that it makes the difference. Understanding the issue is what’s important.
However, rather than repeat my arguments here at length, I suggest you read:
It will take quite some time, but if you really want to undertand the issue, it could be worth it. It will not tell you everything, but it should dismantle the idea of kProbe/LiteOn as a useful ‘de jure’ measurement standard (de facto standard it could not be to begin with).
If you want to understand how dvd player reading implemenation works, I suggest the Ibrahim book (2003) above. ODS Mag articles are also quite useful in detailing how focus/offset tracking and slicer implementation are left to the reading drive (as is RSPC handling on chip level as an interplay with error correction and optical tracking control).
Also, as a last point, let us not forget that a scientific view on the error rate scanning data would require modern statistical analysis of the results, something which is yet to be done by any author here or elsewhere.
PS Your link was to the ‘firmware’ forum, but I assume you meant the ‘writing quality’ forum, which I’m quite familiar with, as you will see from my posts there.
