NEC3520A燒錄過程中每500MB就會使用AOPC的樣子...?

The ND-3520A incorporates NEC's "high resolution writing strategy" and
"Active Optimized Power Control" (Active OPC) to enhance the quality of
written data. Active OPC dynamically monitors writing power and reflection of
the media in use, calculating the optimum laser power and adjusting it in
real-time, to overcome issues such as fingerprints on a disc.

不過卡拉聲我倒是沒聽過就是Orz
