Theoretical problem-can a cd still work if nicked by nail

post #1 of 6
Thread Starter 
First off, no I did not scratch any cd's...this is just something I thought of

So you have a half-full cd/dvd 1-layer and you take a nail and cut a tiny but deep indentation at a certain place throught he metalic layer (the data layer, not the clear plastic). Due to data literally ordered in tiny pairs around the disk, you somehow indent a place where there is no data.

My question is, will the disk still work? If so, can it be copied by a cd-burner?
Final thing, I'm getting the general data ordering on the cd right,and this whole thing is viable at all?

If it damages an area without any actual data, then it wont be a problem.

Ok, and the said disk can still be copied right? Lets say the hole is completely through the disk.

Can one program into the burned image, that if the CD or DVD is "executed" (opened by clicking it as a drive in my computer, or simply inserting it into a computer), the code where there is the big break is to be skipped a certain length which corresponds to the track (subcode?)? Finally, how can it be determined "where" the code is on the .4micron thick track so one can know in what general vincinity there must be junk data?

This is for a programming course I'm taking. My project is to make a cd that can only be read on the PC as opposed to sony's which they say could only be read on cd players.

It has to be a music cd and it has to be burned as a music cd (burning as a data cd does not count.
