BD-R LTH

BD-R LTH is an organic-dye recordable Blu-ray type whose written marks have higher optical reflectivity than the unrecorded material.

JVC identifies LTH as requiring explicit device support, sometimes enabled by firmware [1]. A Blu-ray label alone does not establish compatibility with this recording type; incompatibility is not evidence of aging.
