Both actually.  Commercial disks are encrypted with the keys distributed
to the players in their firmware AFAIK--this makes it so that only select
manufacturers can play and/or create commercial video disks.

For most uses there are better options than Blu-Ray disks; there is a
small window in around the 100GB range that they might be useful but
honestly it would be more reliable at similar cost to buy a used LTO tape
system for that purpose.  In general I wouldn't trust organic optical
media; the lifetimes are much, much shorter than typically stated even
when stored in a cool dry environment.  Blu-Ray disks' primary use is for
DRMed movie distribution; if it weren't for that they would have become
obsolete long ago. :-)
