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
August 2006, BD-R/RE drives up to 4x retail for about $1000 and 2X
single-layer BD-R discs, with a capacity of 25 GB, can be found for
$15–$20. The theoretical maximum for Blu-ray Discs is about 12x as this is
the speed of rotation (10,000 rpm) that causes too much wobble for the
discs to be read properly, similar to the 16x and 52x maximum speeds of
DVDs and CDs.
