Blu-ray Disc recordable (or BD-R) refers to two direct to disc optical disc recording technologies that can be recorded on to an optical disc with an optical disc recorder. BD-R discs can be written to once, whereas BD-RE (Blu-ray Disc Recordable Erasable) can be erased and re-recorded multiple times. Disc capacities are 25 GB for single-layer discs, 50 GB for double-layer discs, 100 GB for triple-layer discs, and 128 GB for quad-layer discs.[1]

There are four versions of Blu-ray Disc Rewritable (BD-RE) and three versions of Blu-ray Disc Recordable (BD-R). Each version includes three Parts (a.k.a.

BD-R LTH (Low To High)
BD-R LTH is a write-once Blu-ray disc format that features an organic dye recording layer. "Low To High" refers to the reflectivity changing from low to high during the burning process, which is the opposite of normal. The advantage of BD-R LTH is it can protect a manufacturer's investment in DVD-R/CD-R manufacturing equipment. Only modifications are required to current equipment; no investment in new production lines is required. It is believed this can lower the cost of disc manufacturing.[23]
Old Blu-ray players and recorders cannot utilize BD-R LTH; however, a firmware upgrade can enable devices to access BD-R LTH. Panasonic released such a firmware update in November 2007 for its DMR-BW200, DMR-BR100 and MR-BW900/BW800/BW700 models.[24] Pioneer was expected to ship the first LTH BD drives in Spring 2008.[25] Sony upgraded the PlayStation 3 firmware enabling BD-R LTH reading in March, 2008.[26]
