"why P-CAV is not adopted" Plextor answered "...CAV recording can never be better than CLV recording. The drive sets a certain write strategy depending on the disc type and the speed. For CLV, these are kept the same throughout the disc. For Z-CLV, they stay the same within a certain zone. But for CAV, the speed constantly changes. So in theory you need millions of write strategies. It's as if you have thousands tiny Z-CLV zones. So you have to compromise, probably on quality and accuracy..."
這代表 Z-CLV 燒出來的品質應該會比較好嚕?

這是他們的推論吧
就是說用Z-CLV的方法
機器只要根據少數的幾個區域來擬定燒錄策略
但是如果用P-CAV的話
幾乎是等於要用幾百萬個燒錄策略
因為燒錄的速度是一直改變的
所以P-CAV的方法等於是把光碟區分為幾千個區域來做Z-CLV
因此在品質與準確度上可能... |
