As for the drive which is used for entry "DVR-A06" of the same company. You say that with same ones as the commercial item,

by the fact that just the firmware is modified in individual ones, without remodelling mechanism and the like inside, 2 layer record is possible.

Furthermore, 2 layer record is not decided yet with the forum, there is no schedule and the like of release of the firmware.

訪談裡好像是說只有改韌體

不過就我拜訪國內某大光碟代工廠的感覺
目前國內光碟廠對雙層片似乎沒太大興趣
至少那一家今年對雙層片量產時期尚未規劃
雖然都說做得出來 但以技術宣示為主
對國內廠的特性來說 應該還是等市場出來才會去做吧(衝量)
雙層片剛出來應該是大多是日本製
所以說 看來至少在Q4前不會有便宜的片子吧
我猜剛出來可能要200~300 一片吧
.........純猜測
