A CD uses optical technology to read data stored on the surface of the CD by reading "BUMPS" or semi-reflective "burn" marks on the medium and interpreted similar 1's & 0's binary format just like in magnetic data storage such as that in Hard Disk Drives. It should be possible to recover the data depending on where the data is physically stored. There should be sufficient technology to go about this, There are companies that do this type of work for different purposes. It could be personal data recovery of very important files or perhaps it could be confidential information. Whatever it is that's stored on a disc, if your goal is to make it unrecoverable it would be to completely shred the disc or burn it, you could also achieve this by sabotaging the aluminum like surface area of a disc.
They are broken into sections which we call Plates.
Recovery from a broken leg will likely take several months, if it is possible at all. Broken legs used to be considered untreatable. Thanks to veterinary science we can now save some horses who suffer broken limbs.
