Those are the ones I use.

>> Interesting that Doug mentions the Mitsui brand as being excellent.  It may be today but time will tell - about 10 years ago I bought Mitsui exclusively as they were rated the best.  Sadly I am finding that more and more of them are failing - one I needed to make a copy of last week not only wouldn't play at all, I couldn't even do an error check with Plextools and a Plextor drive.  A further check showed that 6 out of 10 sampled, although playable, had problems (and 4 of them had no C2 or CU errors at all).   Who knows what our Taiyo-Udens will be like in 10 years time although my 5 and 6 year old ones seem to be OK at the moment..Thank goodness hard drives are now so cheap that I can keep backups of everything and thus avoid such problems.

>>> CD recordable technology is a complex and convoluted subject. There are many factors that come into play when recording a disc: the rate of spin, the formula of the dye, the ambient temperature, the internal temperature, the age of the media, the power and wavelength of the laser, the spacing and size of the marks on the media relative to the speed of the disc, to name but a very few. Media manufacturers are constantly adjusting the myriad factors of disc production, including but certainly not limited to the formula of the dye polymer. CD-R media must combine the properties of compatibility, writability, readability, and data longevity. To say that a certain dye formula or brand of media is inherently better than another based exclusively on one of these properties is not only simplistic, it is misleading.
