In order to discuss about a certain CD-R media, we need to know who made the disc. The brand that the media has been sold under doesn't actually tell us anything yet. For example the well known brand TDK is usually made by these 3 manufacturers: 1) Taiyo Yuden - very high quality 2) RITEK - very high quality 3) TDK Corporation - sometimes these give problems. The key for finding the manufacturer is the so called ATIP information, stored in every CD-R disc. And the software that we can use to read the ATIP and copy/paste to this board is the CD-R Identifier. http://cd-rw.org/software/cdr_software/cdr_tools/cdridentifier.cfm The information we can dig out with CD-R Identifier looks like this. ATIP: 97m 32s 00f Disc Manufacturer: TDK Corp. Reflective layer: Dye (Long strategy; e.g. Cyanine, Azo etc.) Media type: CD-Recordable Recording Speeds: min. unknown - max. unknown nominal Capacity: 658.74MB (74m 59s 00f / LBA: 337275) This disc is a bit older TDK REFLEX CDR-74min certified at 12x write speed. We can see that it is made by TDK. So, in order to ask a question about a CD-R or submit your experiences about a CD-R you will need to: 1) Write complete brand & model of the CD-R 2) Post the ATIP information In order to keep the board organized it would be nice if discussions about a certain brand, like TDK, would be held under one thread, but the admins will take care of that if you are not able to. If you have problems with CD-R Identifier, at least the Feurio! is also able to give you the same information about a CD-R disc. http://cd-rw.org/software/cdr_software/cdr_applications/feurio.cfm Happy burning folks!
