There is no media specification yet for 18x or 20x speed, neither from DVD-Forum nor +RW alliance. Hence we stick to 16x media as we only provide media to the markets that meet the specifications given by the industry organizations. If they agree on a standard, we will try to meet it and bring equivalent media to the market.

We have also started testing for the mechanical stability at those high speeds. Some people may still remember the stories about “exploding” CD-R media at 52x speed when this speed was introduced for CD-R recording.
