For those that need good BR burning software to go with these I use Ashampoo Burning Studio Free and it lets me burn anything from CD to VCD to DVD to BR as well as music and data discs, highly recommended.

Excellent discs, I never burn a coaster with Ridata

I've used them for 10 years, and, in all of that time, have had no more than a handful of bad discs out of the nearly 1000 discs burned.
