@xxq2112 你的数据看起来更像是 ROM 盘而不是刻录盘。ROM 盘因为是压制而不是刻录,只要盘体不变形就没什么问题。 https://en.wikipedia.org/wiki/Media_preservation#Optical_media_-_CD,_DVD The National Archives and Records Administration lists published life expectancies to be 10 or 25 years or more for normal CDs and DVDs and conservative life expectancies to be between 2 and 5 years.
