The compact disk player which inherited the
technical thought of the high-class machine and was developed.
The
oversampling digital filter was adopted 4 times, the sampling frequency of
44.1kHz was pulled up to 176.4kHz, 4 times, by arithmetic processing, the low
pass filter of the low degree was made into the enable, and the audio property
of a low distortion with few circumferences of a phase to a high region is
realized.
Moreover, the separation property is improved by the digital
analog converter of a right-and-left independency.
The disk stabilizer
of the magnet clamp scheme which fixes a disk by the attraction of a magnet is
adopted.
Since it is a non-contact type, it has prevented that an oscillation of
a disk gets across to a pickup or other circuitries.
In addition to the floating structure which floated the optical-system
mechanism from the chassis, the ballast base which lowered the centroid
of the mechanism chassis rather than the support part of the mechanism
is adopted.
The oscillation was suppressed by fixing this to ceramic mecha support
excellent in the periodic-damping property, and reading of the stable signal
is realized.
The honeycomb
chassis which put the honeycomb-like rib into the sole plate of a chassis is
adopted, and the unnecessary oscillation from the outside is reduced by
improving rigidity.
The auto special-NetWare-program edit and the pause
program function are carried.
The power-source on-start functionality in
which a timer start is possible is carried.
