The compact disk player which carries the formal
specification focused on a tone quality, and a variegated edit function.
The "auto edit function" which programs automatically how many
music can be recorded is carried within the time which specified. Moreover,
the "auto space functionality" to set up automatically the null
for a minimum of 4 seconds is carried between music.
The 16-bit digital filter is adopted, by
oversampling, the space character of a music signal and a sampling noise was
extended, and the burden of an analog filter is eased.
The pickup part
was put into practice, the floating of a low profile and the fraction which is
easy to be influenced by oscillation while carrying out a weight saving was
carried out, and the unnecessary oscillation is eliminated.
3 beam laser
pickup with two sublaser lights for a detection shifted to right and left other
than the main laser light which reads a signal is adopted as a pickup part.
Thereby, the tracking error was detected and the error is prevented by the
The intro scan and the 24 music random program memory
