Theoretical question about how CD's work

Theoretically, can the contents of a CD be printed out onto sheets of paper in 1’s & 0’s, re-entered digit by digit (say, by a generous helper monkey with an infinite lifespan) into some sort of program, and the same sound will be replicated? Just trying to understand how CD’s work (though I’ve been trying for 25 years and it still seems like magic to me).

I love that the OP has orphaned this thread, but people are still arguing about how CD's work.  :D :D :D

Hey sealrock -


Imagine a record. On it, you can see the sound waves of the recording. The vinyl track gets deeper, or taller depending on the signal.


Now imagine you could measure the depth of the grove in precise increments and you did this every 1/1000 of an inch of grove length. Write that depth down. That is your digital signal.


Best,

E
