the expectation of the mdisc dvd verbatim is counted from the date of manufacture disc or from the date of burning??? i burned disc in 2016 I do not know the year made disc

Yes. Mix of both. Weighted more towards the burn date.

1) When you posted that my mdisc would live 15 years at maximum was counted from the year of burning or date manufactured? how do I find out the year of manufacture of MDisc DVD Verbatim?

2) 1) Did you say that my mdisc verbatim DVD will live 15 years under my storage conditions but 15 years it used constantly or burned storage without use? how many years? mdisc uses inorganic dye does not use organic dye
