After some years of trying out every cd-r brand i could find, i saw these philips discs. They are rugged, well made, and have never given me errors whilst burning. Also, they work fine as audio cds even tho the specification above says no.
The top surface is also a slightly rough texture so that you can write easily on it and see which side is which, and there is plenty of space to write whatever you need to.
Id reccommend these to absolutely anyone, and amazon is by far the cheapest place to get them.
