Can more experienced engineers give me their input on this. If I open a CD player, what electronic parts should I expect to find?

    \$\begingroup\$ May I refer you to a type of DNA sequencing called "shotgun sequencing". To characterize the DNA of certain organism, it is blasted into millions of pieces, then sequenced in parallel. I suggest the same with a CD player, using a big hammer and a room full of people. :D (I kid..) \$\endgroup\$ – tyblu Jan 13 '11 at 21:27

    \$\begingroup\$ The general process you are asking about is often called a teardown, which is used by engineers to examine a product. Searching for CD player teardown will find one at iFixit, that can give you a general idea even if you do not have the same model. ifixit.com/Teardown/Sony-CD-Walkman-D-NF430-Teardown/1249/2 \$\endgroup\$ – mctylr Jan 13 '11 at 22:41

By searching the web, you'll find plenty of information.

Here's a teardown of a CD player.

Here's a picture of the internals:

Here's a basic guide to the workings http://electronics.howstuffworks.com/cd4.htm

But, the best way to find out is to take it apart.
