[78-L] reliable CD-R blanks

[Alan Bunting]

So far as I know Plex-tools is the only freely available program which will measure error rates but, unfortunately, it only works with a very limited number of drives, most of which were made by Plextor and are no longer available.  Although they still produce DVD/CD-R drives (including several external USB ones) which will run PlexUTILITIES, (the latest version of Plex-tools) none appear to be currently available in the UK.
The only alternative is to purchase a custom checker such as the Clover DVX-4 but the cost is beyond normal mortals such as me.

I've wondered how the results of a burn were known or quantified. Nero 
simply says it passed or did not. Is there a tool that works with other 
drives besides Plextor?

>> 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.
