What isBD-R

BD-R or Blu-ray Disc Recordable is a type of Blu-ray disc that allows data to be written on it only once. It is a subcategory of Blu-ray Disc Recordable Erasable (BD-RE), which can be erased and written multiple times. They both use the blue laser technology, which allows greater data storage compared to conventional CDs or DVDs. BD-R can store data from 25 GB to 128 GB while the recording speed is rated at a minimum of 36 megabits(4.5 megabytes) per second. The BD-R and RE discs use grooves and a wobble frequency to locate the read and write laser on the disc. These discs also have a calibration zone to minimize rejected discs and drives during production.
