Again, for all the real information regarding CDR's please visit www.cdmediaworld.com There are only 12 manufacturing plants in the world. Mitsui and TY are two of them and they make, what are reported to be, good discs. However, people have complained that Mitsui's have begun to peel. Not good.
The 12 plants make CDR's for all the brand names out there and the brand names change plants every other week. Or, so it seems. So, you can never be sure who is making your favorite disc unless you visit the above mentioned site or have a computer which can read the inner groove of the CDR which has the information incripted.
The best rule of thumb is to stay away from any disc's that are made in Tiwain. These plants there have poor quality control and independent labs have determind that they do not hold up well. Ritek and Printco(?) are two of the lesser manufacturers.
Also, note that the average life of a disc is undeterminded at this time. I have had disc's that were made on "the best" media which would not play after 1 year. Refer to past post "vaporware".
If you want information from those that have used thousands of disc's over the years you should visit www.oade.com and review the taper's sections.
This is a page dedicated to folks that tape live concerts and use CDR for trading and back up. There is a great deal of experience there and should be helpful with questions and infromation regarding anything involving recording.
