Verbatim offers DVD media in different quality grades.
The top of the Verbatim line is the DataLifePlus (AZO) series that Verbatim regards as the "highest" quality. The mid-line is the AZO (MCC) series that Verbatim regards as "superior" quality. The bottom of the line (contracted out landfill grade media) is the Life series that Verbatim regards as "good" quality. I use the mid-line AZO series for duplication and computer backups.
I do not use 16x media in my many stand-alone Panasonic, Philips and Magnavox HDD/DVD recorders and DVD recorders. Why is that? I want better quality burns while reducing stress on laser assemblies in these expensive to replace proprietery DVD Drives. That dictates the use of 8x media.
With generic DVD burners fitted to duplicators and computers I use 16x media as it is easy and inexpensive to replace DVD burners with failed laser assemblies.
I prefer to use JVC/Taiyo Yuden 8x Premium Line DVD-R (TYG02) media in my Panasonic, Philips and Magnavox recorders. I also use JVC/Taiyo Yuden 16x DVD-R (TYG03) media for duplication and computer backups. (In late 2008 Taiyo Yuden bought out the JVC Optical Media operation. More recently Taiyo Yuden media is sold under the dual JVC/Taiyo Yuden branding. JVC no longer produces optical media.)
The first photo shows the original Taiyo Yuden and current JVC/Taiyo Yuden spindle wrapper labels and inserts. The second photo shows a JVC/Taiyo Yuden 8x Premium Line DVD-R at the upper left, a JVC/Taiyo Yuden 16x DVD-R at the lower left and a Verbatim 16x AZO DVD-R at the lower right. Notice the Verbatim "AZO" logo seen on the spindle insert seen at the upper right.
