+R 片吧
我的PX-716用這個很合，加上BookType的修改，並沒碰到什麼問題

而且還有個原因，就是-R片上有一部分資料是沒有保護的

In one ECC block pre-pits carry 192 bits of information (one pre-pit block). Out of these 192 bits, 48 are not protected by any error correction mechanism, 24 bits are protected by 24 bits of parity (A parity), and the last 56 bits are also protected by 24 bits of parity (B parity).

如有錯誤請糾正哦!~謝謝
