謝謝啦~

We have seen that out of 32 bytes read from the CD as one "frame", we only use 24 bytes in our final data. Four of the bytes are used in the first stage of correction, the remaining four are not used till the second part. This first stage is called C1, if you like Correction one. At this point, we have 28 bytes of data, plus four bytes which help us locate any errors, just like in our previous section. Using some funky mathematics, we can detect if those 28 bytes are correct, and if not we can fix a single error straight away, making those 28 bytes good. If we cannot fix the error, there are now only a couple of options open. Some CD players attempt to fix two errors, which is possible if there really are just two errors, however the mathematics is not so reliable for more than two errors. Several errors could create a situtation that looks like only two errors, and we can end up with a frame that we think is good, but is in fact bad.

所以,他一次解一個 Frame ,看 28 bytes 有無錯誤。而且說超過兩個錯誤不一定能解,所以這下 C1 怎樣影響音質可能有方向了,謝謝~
上面這段話有說,利用奇異的數學算法,可以馬上知道有無錯誤,有些光碟可以更正兩個錯誤,但這只在只有兩個錯誤的狀況,超過的話,就不準確了!看來 C1 好像還是有限制存在...

嗯,有機會再去看看有沒有人有紅皮書了。
VanHalen 大也謝謝您,如果您在光儲存產業,小弟不會很驚訝,也謝謝您的指教,謝謝您花時間註冊,謝謝您與大家抬槓。其他,個人覺得在這裡討論如果要說服別人,是件困難的事,所以,看開點。
不過,小弟覺得,大家都沒提出有沒有 FIFO 的證據,全部用推測,你不信我我不信你有啥意義?另外,FIFO 和 Cache 的道理與用途如果仔細分是不同,不應該把他搞在一起。FIFO 是一回事,Cache 又是另一回事。
信與不信,其實決定權落在與討論人一點關係都沒有的論壇各位看官,所以有參與討論的大家都不用大冒肝火吧~
不論如何,謝謝大家讓小弟多一點瞭解,不過,看來要去找資料,因為,目前討論大家捫心自問沒有資料沒人會服自己的論點的。看來要弄到 CD-ROM 的規格書 與 晶片的 Datasheet 才行了...
可是,有喵過 DVD 的 Spec... 跟天書一樣,超級厚...
