CD blanks are needed - in contrast to blank DVDs - now and again if you want to burn an audio CD, for example, for an old car radio. for data backup is taken of course DVD discs that provide more gigabytes of storage per Euro. The JVC / TDK blanks mW manufactured by the company Taiyo Yuden, which is known for very high quality blanks and in tests in terms of product quality always cut very well. The blanks, which I received were manufactured in Japan and can be printed by inkjet. So far, all firing tests were successful, and I never ausreize the 52 times the speed, but burn with half speed.
In addition (april 2015) I want to clarify that I have from the manufacturer actually annovaukde the original depicted JVC receive blanks. I can not judge whether other providers under the same project inferior products that do not conform to the product description distribute. Seems to be so loud the other reviews.
