Blu-ray Disc recordable refers to two optical disc formats that can be recorded with an optical disc recorder. BD-R discs can be written to once, whereas BD-RE can be erased and re-recorded multiple times. As of March 2007, BD-R/RE drives up to 4x retail are sold for about $600 and 2x single-layer BD-R discs, with a capacity of 25 GB, can be found for around $12. The theoretical maximum for Blu-ray Discs is about 12x, as the speed of rotation (10,000 rpm) causes too much wobble for the discs to be read properly. This is similar to the 20x and 52x respective maximum speeds of DVDs and CDs.
