2. What is Blu-ray Disc?
Blu-ray Discs (BD) are optical discs developed to enable burning and
playing High-Definition video (HD), or to store data. BDs are burned using
different technologies from CDs or DVDs, but can be made compatible
with the appropriate hardware. BDs can be single-layer (2 hours HD/25GB
of data) or dual-layer (4 hours HD or 50GB of data). CyberLink
PowerProducer supports burning to rewritable, single-layer Blu-ray discs.
3. What are HD DVD Discs?
HD DVD (High Density Digital Versatile Disc or High Definition Digital
Video Disc) is a digital optical media format that can hold high definition
video or other data. HD DVD is similar to the competing Blu-ray Disc,
which also uses the same CD-size (120 mm diameter), optical data storage
media and 405 nm wavelength blue laser.
