From: "Frank Haber" 

The data CD formats have sectors, with headers, like other rotating-storage
media.  They do *not* use the interleaved-and-offset
"burst-error-reduction" schemes of the original (redbook later)
audio format.  So in theory.....

In practice, lots of luck in glueing on the shattered piece at the proper
diameter and angular orientation, balancing the resultant mess, etc., etc.
Now, with about $80 million and a polar-coordinate  machine tool or
plotter, who knows what you could do?
