About DVDs
Music CDs and DVDs have grooves (tracks) in
which the digital data is recorded. The data is
represented as microscopic pits recorded into
the track – these pits are read by a laser beam
to play the disc. On DVDs, the density of the
tracks and pits is twice that of CDs, so DVDs
can contain more data in less space.
A 12 cm disc can contain one movie or about
four hours of music.
In addition, DVDs provide sharp picture quality
with vivid colors thanks to a horizontal resolu-
tion of over 500 lines (compared to less than
300 for VHS tape). With the addition of an
optional, digital audio processor (PXA-H510),
you can recreate the power and presence of a
movie theater with Dolby Digital 5.1-channel
Surround.
