Plextor and
the PX-B900A Evolve with BLu Ray Technology.
Blu-ray, also known as Blu-ray Disc (BD), is the name of
a next-generation optical disc format jointly developed by
the Blu-ray Disc Association (BDA). The format was developed
to enable recording, rewriting and playback of high-definition
video (HD), as well as storing large amounts of data.The
format offers more than five times the storage capacity of
traditional DVDs and can hold up to 25GB on a single layer
disc and 50GB on a dual-layer disc. This extra capacity combined
with the use of advanced video and audio codecs will offer
consumers an unprecedented HD experience.While current optical
disc technologies such as DVD, DVD�R, DVD�RW,
and DVD-RAM rely on a red laser to read and write data, the
new format uses a blue-violet laser instead, hence the name
Blu-ray.
Despite the different type of lasers used, Blu-ray products can easily be made backwards compatible with CDs and DVDs through the use of a BD/DVD/CD compatible optical pickup unit. The benefit of using a blue-violet laser (405nm) is that it has a shorter wavelength than a red laser (650nm), which makes it possible to focus the laser spot with even greater precision. This allows data to be packed more tightly and stored in less space, so it's possible to fit more data on the disc even though it's the same size as a CD/DVD. This together with the change of numerical aperture to 0.85 is what enables Blu-ray Discs to hold 25GB/50GB.
