Verbatim BD-R LTH media is manufactured with an organic dye that turns the disc's reflectivity during recording from "low to high". Other BD-R discs use the "high to low" recording method. Additionally, BD-R LTH is manufactured on converted CD-R/DVD-R production lines, which utilize a spin coating process and allow excess materials to be recycled. These two cost-cutting measures let us pass along the savings to you. Upon introduction of the BD-R LTH media, key hardware manufacturers like Sony, Pioneer, Panasonic and LG have worked to assure that their burners are fully compatible.

If your Blu-ray hardware was manufactured before 2009, check with the manufacturer for firmware updates. own to High (LTH) - BD-R LTH is the same as all other Blu-ray media, except it's manufactured using a more efficient production process.
