 CD ROMs incorporate Error Correction Codes. A few mangled bits can be 
reconstructed on the fly. If they didn't have ECC's they wouldn't have nearly
as many advantages over conventional media as they do.

 ECC's are pretty old hat actually. They are common in the large mini and
mainframe world where a fried byte of memory could mean shuting down a
multimillion-dollar installation.
