[Tex/LaTex] tikz stacked disks 3D

Question

I would like to know if it is possible to draw an image like this in 3D using tikz? I am having some text around this picture, which looks great in tikz, but I am unable to draw this kind of 3D figure in tikz. Also the shadows around it looks quite complex to me.

Any examples, ideas, suggestions?

Thank You !

Definitely not perfect in any respect but anyway...

\documentclass[tikz,border=5]{standalone}
\tikzset{pics/.cd,
  disc/.style={
    code={
      \fill [white] ellipse [x radius=2, y radius=2/3];
      \path [left color=black!50, right color=black!50, middle color=black!25] 
        (-2+.05,-1.1) arc (180:360:2-.05 and 2/3-.05*2/3) -- cycle;
      \path [top color=black!25, bottom color=white] 
        (0,.05*2/3) ellipse [x radius=2-.05, y radius=2/3-.05*2/3];
      \path [left color=black!25, right color=black!25, middle color=white] 
        (-2,0) -- (-2,-1) arc (180:360:2 and 2/3) -- (2,0) arc (360:180:2 and 2/3);
      \foreach \r in {225,315}
        \foreach \i [evaluate={\s=30;}] in {0,2,...,30}
          \fill [black, fill opacity=1/50] 
            (0,0) -- (\r+\s-\i:2 and 2/3) -- ++(0,-1) 
            arc (\r+\s-\i:\r-\s+\i:2 and 2/3) -- ++(0,1) -- cycle;
      \foreach \r in {45,135}
        \foreach \i [evaluate={\s=30;}] in {0,2,...,30}
          \fill [black, fill opacity=1/50] 
            (0,0) -- (\r+\s-\i:2 and 2/3) 
            arc (\r+\s-\i:\r-\s+\i:2 and 2/3)  -- cycle;
    }
  },
  disc bottom/.style={
    code={
