I find out with my new 25-spindle of DVD-R 16x (MID code TYG03) that blank DVD's stick a bit ont the fingers when yo touch them on the edge and that this pack of 25 smells stronger that my oldier spindles.
Maybe it is because these 16x rated ones have been manufactured (in Japan) more recently than my TYG02 and TYG01.
For a single DVD in a jewel box it is harder to tell ...
I dont think that these dogs are able to smell the different dyes (cyanine, Azo, ...) and distinguish blanks or burned discs from pressed ones.
This dye is supposed to be well sealed inside and protected against the penetration of oxygen.
Either the polycarbonate but more probably the glue
used for bonding all
DVD's (pressed and burned ones) must have a special smell.

I think that the larger the quantity of DVD's is in a parcel the more efficient the dogs are,
as I cannot see these dogs sniffing out every single
pressed DVD sealed
in a jewel box with the transparent
From this news I learned at least that there is a (little) way to tell if a spindle of blanks is still fresh
(because there is no date for conservation on blank DVD's ...)
