其實cdfreaks先前有報導過相關的消息
後來菲利浦公司看到訊息之後，便給了cdfreaks更多相關資訊
其大意大概是這樣子的(小弟英文不好，若翻譯得太差還請包涵喔)

At this point in time we are demonstrating the feasibility of the double layer 8.5 GB DVD+R technology. We are able today to make a recording on prototype double layer DVD+R media using a prototype writer based on the
current Philips 8x recorder and a single brand of prototype media optimized for the current recorder based on our joint research efforts with MKM (Mitsubishi Chemical Media red.).
"這次我們展示了雙層的8.5GB DVD+R的技術,利用
目前的8倍寫(當然是菲利浦自家的)DVD燒錄器及目前的原型燒錄片，加上研究團隊使用MKM(這小弟也不懂是啥東西)努力的對燒錄器最佳化後，我們已經能燒錄雙層共8.5GB的DVD+R"
The specifications will not be finalized until the end of December 2003 and we will not know how the hardware interacts with new media until such time as it has been manufactured according to the final specification by
multiple vendors.
"至少到年底，spec都無法制訂完成，因此在各家廠商依據最後的spec生產出產品
之前，我們並無法知道硬體與新的儲存媒體間的相互影響"
A firmware upgrade to an 8x drive enabled the prototype drive to record on a specific 8.5 GB DVD+R prototype disc produced by MKM. However, it is likely that new hardware (such as ICs) will be required in the final product to accommodate variations in media and drives from different vendors. At this time, we can say with certainty that 4x, 2.4x and 1x drives lack the requisite laser power to burn a double layer DVD+R disc.
"對8x 燒錄器進行韌體升級能夠讓原型機藉由MKM的幫助燒錄8.5G的DVD+R,但是，它已經接近一台新的硬體，而且需要最終調整以適應各家廠商所推出的各式產品。但以目前來講,我們能確定的是,現有的4x、2x和1x的DVD+R燒錄器由於其雷射功率不足，因此是絕對沒辦法燒錄雙層的DVD+R碟片的"

總之，就是8x機子還是有機會能升級成燒錄雙層DVD+R的機器....
而4x以下機器就別想啦....
小弟才剛訂了A06-J說...竟然給我出現這種消息...
現在小弟只能祈禱..
"8x DVD+R燒錄器絕對不能給燒雙層的DVD+R啊~~~~不然小弟會氣死說"
