It is Ricoh blanks with the Manufacturer ID RICOHJPN R02 which harmonize well with the LG GSA-4082B and can really describe 8x. The "printable" surface can be labeled good and the burned DVDs can easily play on my DVD player Centrum. For me, therefore, 5 stars. Tests (eg: C't 10) however show that Ricoh blanks - as others 8x blanks also - give good results only with specific recorders. My tip: I Before buying on the net or in magazines verify the suitability for its own DVD burner avoid bitter disappointments.
