Wasn't sure where to post this so started a new thread.
This is a list of best to worst DVD recordable media.
If there are any brands not on the list feel free to add any disc brands you have and the manufacturer ID.If this information can be put somewhere else on AD(or has already been posted), let me know!
Regards Crowy.
This is a worthless exercise unless one specifies:
1) type of testing equipment--Datarius, Pulstech, Audio Development CATs, and Expert are considered the authorities.
2) production line--a Steag Hamatech line will produce slightly different results for given M-code from those results from a different production line. All manufacturers strive to get identical results on differing lines, but variabilities remain due to different tendencies under identically changing conditions. An increase in humidity, for example, may affect two different coating lines differently.
3) production codes--those codes identify the production lines
4) field IDs to determine whether or not there is any stamper deviation in the "ideal" write strategy
5) stamper ID--stamper geometry is far more important than most people realize
6) model of recording drive and its version of firmware (Only factory-issued firmware should be included because only the factory has the equipmment listed in #1
7) recording software used--there are amazing differences in versions and compatibility with drives, even though one would not expect them
Without these criteria, any report of quality is merely a report of what worked and what did not, and the issue of compatibility raises its ugly head. The ranking of digitalfaq appears to be anecdotal reporting of compatibility with some quality issues mixed in with an undefined ratio. The technical descriptions are bogus. There is one good "archival" code in the 1st class media ranking and several others in the "not suggested for archival" grouping. (Archival testing can take as long as 10 months in heat/humidity chambers; so test results do take a long time. Is the author using Eyring or Arhennius test results? Probably just anecdotal reporting.)
Let digitalfaq spread its misinformation on its own site. Repeating it here is duplication of almost useless information (ALMOST useless because the ratings do correlate with the chronology of firmware releases or lack thereof rather well. For anyone interested in seeing who gets the support and who does not, this information can be useful.) There are many other technical errors in this listing that I would discourage anyone from relying on it at all for any information regarding quality. Duplicating it here does a disservice to the members of this site who are truly interested in learning something.
That would take too much time, and I don't know how to find out about all of the factories and what equipment they are using. Some equipment is being moved around to Viet Nam, Hong Kong, and Malaysia from Taipei to avoid levies placed by some countries on media manufactured in Taiwan. In other cases, some brands are moving from one manufacturer to another: 1) Maxell has designated Ritek as the producer of its optical media except blue laser product; 2) Verbatim (listed for having "some sourcing" in the digitalfaq listing when, in fact, almost everything is sourced) has moved some sourcing to MBI. Then there is the question of dyes and new formulations. New M-codes for 20X product. Decoding every production number because each factory uses a different code. It would take a month of solid work with very little help for anyone.
I think that the bottom line is that you should use whatever discs give you the best results with whatever disc/burner/firmware/PC/software configuration you are using
Personally, I am comfortable using Verbatim/Maxell/Sony DVDs and Maxell/Sony/FujiFilm CDs . . and have enjoyed great success with these brands with my systems

If you dont know how to ignore a posting, complain to
me and I will be only too happy to demonstrate . . .
When are they actually going to update this list? I've seen this thing since early 2003. Media must have changed, since I burn CMC Mag with no problems and its compatible with all my (new) DVD players.
