Ritek版面水藍 80min A+ 5
Ritek版面仿金 80min A- 4

這個不見的準...

這個測出來的數據的準確度如何呢?有沒其他可以測的軟體來做比較

光碟的評比應該是Feurio的公司用專業儀器測試的，Feurio這套軟體只是照ATIP比對資料庫內的資料，所以資料不一定正確，因為相同的光碟片在國外可能是A級片，但是在台灣賣的卻是C級片...

沒錯...:(

只能說在國外是A級的，在國內可能是C級
但應該沒有廠商把A級片留在台灣賣，然後C級片賣到國外吧
所以在國外就已經測出是C級的，可能真的要小心品質了.....

又搞了一晚，還是不行，那個Output ATIP Information選項是灰的不能選，難道不支援plex4012?

Beta is a physical parameter of CD, not the quality.

see orange book II.

引用:

Beta is an alternative asymmetry measurement. It is more applicable to recorded CD-R discs as CD recorders continuously monitor this parameter to optimise write power while recording. Generally, a low value of Beta means that the disc is recorded close to its optimum power. High values of Beta indicate poor recording. The result should be less than 20%.
