Definition of Blu-ray Disc recordable
Blu-ray Disc Recordable (BD-R) and Blu-ray Disc Recordable Erasable (BD-RE) refer to two direct to disc optical disc recording technologies that can be recorded on to a Blu-ray-based optical disc with an optical disc recorder. BD-R discs can only be written to once, whereas BD-RE discs can be erased and re-recorded multiple times, similar to CD-R and CD-RW for a compact disc (CD). Disc capacities are 25 GB for single-layer discs, 50 GB for double-layer discs, 100 GB ("BDXL") for triple-layer, and 128 GB ("BDXL") for quadruple-layer (in BD-R only).
The minimum speed at which a Blu-ray Disc can be written is 36 megabits (4.5 megabytes) per second.
As of 2024, one of the primary pioneers of the Blu-ray disc, Sony, is winding down production of recordable Blu-ray discs in its plant in Tagajō, Japan. Sony plans to gradually cease its manufacturing of optical media, including recordable Blu-ray discs.
