2-43] What are the gory details about how are 1s and 0s encoded?

(2002/12/10)

This section is for people who really want to know what's going on inside.
You absolutely do not need to understand any of this to successfully record
a CD. You will come away with a greater appreciation for CD players,
and also may better understand how some forms of copy protection function.

The sections are written from the perspective of reading a disc. Generally
speaking, the process is simply reversed when writing.

I tried to find a balance between not presenting enough information and
presenting too much detail. My hope is that, when you are done reading
this, you will have a broad understanding of how a CD player turns a lumpy
piece of plastic into music, and will know exactly where to look if you
need further details. If you want the kind of detail found in a textbook,
there are some good ones listed in section (2-43-6).
