And the purpose of the thread is: which manufacturers / patterns / quantities are better and ensure a long lifespan for the media I am, again, referring to the lacquer protecting the side of the disc.
Anyway, besides the top manufacturers it seems that most others have some problems in this regard, so the question really becomes: does a defective or incomplete lacquer lead to a significant shortening of the disc's life ? If so, does it happen regardless of the environment or do external factors like humidity, excessive temperature etc. need to be present for the effect to become noticeable ?[/QUOTE
To answer your question, yes an incomplete or damaged lacquer layer will cause premature failure of the disc.
I did read your post in your first entry last sentence you wrote "So, how should a good coat of lacquer be applied on a DVD?
I suggest that if you want succinct answers you write exactly what you are enquiring about.
If you have no idea what a good layer looks like I suggest that you use a good strong magnifier under strong light and use your own judgement.
This of course means that you have to look at a variety of media from the poorest to the best. If you can't be bothered to do that then just buy quality media like TY or Verbatim as recommended by numerous people on the board.
If you have a batch of discs that look dodgy then get a refund.
