BD-R HTL

BD-R HTL is a recordable Blu-ray type whose written marks have lower optical reflectivity than the unrecorded material.

JVC describes the conventional inorganic recording approach as high-to-low, contrasting it with organic-dye LTH [1]. HTL is not a brand, an archival certification or a quantified lifetime.
