The main difference between LP and CD longevity to me, is that damaged or worn LP cannot be repaired, while less than perfect CD can be recovered/renewed by ripping software and recorded onto CD-R.
Longevity of CD-R depends on the photosensitive dye used. Taiyo Yuden CD-Rs have 100 years warranty. It is also possible to make backup of CDs on HD. Backup for LPs is not possible.
