generation of this ground-breaking design. In Sony's mechanism, the spindle,
motor and optical pickup base unit are rigidly bolted to a sub-chassis, to reduce
any possibility of resonance. When you load a disc into the DVP-NS999ES, the
disc not only moves laterally into the player, it also descends onto the spindle.
Thanks to Sony's design, the disc is always read in a silent, extremely stable
non-resonant environment. Vibration is minimized, along with the servo activity
that vibration can cause. The sensitive RF preamplifier is protected from servo
radiation.
Conventional DVD players use a pivoting base unit (top), prone to
vibration. The Sony DVP-NS999ES uses a rigidly fixed base unit
(bottom), minimizing vibration and its consequent distortion.

only slides into the player, it also descends to the base unit, which is
fixed to a non-resonant base.

When it carries the disc down to the fixed base unit, the loading tray no
longer acts like a door to seal the front-panel loading slot. Sony engineers
