In a matrix code such as 857978 2.1:*:* EMI SWINDON, the black portion of the matrix code is the master ID and the red portion of the matrix code is the stamper ID. In most cases the master ID is burned onto the glass master at the same time as the audio data, while the stamper ID is applied to a mother or stamper made from that master. They can be distinguished by the different ways they reflect/refract light: the master ID is created with the same pits as the audio data and will refract light into a "rainbow" just as the audio data does, whereas the stamper ID is applied mechanically and does not.All pressings with the same master ID are digitally identical regardless of the stamper IDs, so rather than list every known stamper ID, we use a placeholder.
(On many Japanese releases, the master ID and stamper ID are both added mechanically after the glass master has been created, so it is not possible to distinguish between the two.)
大家點理解?{:6_183:} 甘Columbia/Denon点字版又点解色{:6_141:} 如它是說事實的話,第一組号代表master plate母碟ID,第二組号代表從母碟覆制出來大量生產印碟用的stampler ID.
這便說出什麼1A1,1A2,1A3.....都應是同一音質的..... 35ti 發表於 2014-5-15 11:49 static/image/common/back.gif

甘又5一定，stamper系把刀，啄得肉多刀会蝕
所以好既印片厂系不仃Mon住啤出泥既成品，一有QC问提就换stamper
问提在：QC角度5同，臨尾批可能同头三几千只差左好远
