an inquiry from a novice.

[neopsytox]

let me start off by stating that i am not a gamer.
also, i just came across this site about 30 minutes ago, and instead of using the search, being that i wouldn't know exactly what to type into the search to answer my question, i decided to post here. i am not looking for smart alec remarks. i am not stupid, but am only ignorant to this new technology. i would just like someone to explain some things to me or send me to a specific page that intricately answers my question(s).

i understand that when you use a xerox machine to copy a piece of paper, the quality is degraded and it isn't an exact duplicate, it is more like a draft. that it has to do with the light, balance, and the limitations of the magnification of the machine.

when using a cd burner, is it because of the newness of the technology that we cannot exactly duplicate a cd? do you think it will be in the near future or ever at all that cd-burners are created which will make an exact clone?

when someone plays a playstation game, the system isn't writing to the disc, so my big question is why exactly cannot a cd-writer capture all files and data/scripts from the original to be burnt onto the blank? how are these discs being made so special that it has more than just files to copy? by the way, i am also not a programmer, so maybe it has something to do with an assembly language (?)

what is so intricate that the cd-writer isn't capturing that requires a mod-chip to be used when playing a copy? this is something that i do not understand. of course when playing a console game on the computer, i understand the use of an emulator, but when using the actual console itself...well, i would just like an explanation.

i am not a hardware guru or game buff or programmer. i am just an average person with questions that pop into my mind at anytime, questions that i like to have answered for the benefit of knowledge.

In the first place any original cd, be it PSX game, PC game, application. music or whatever, are pressed and not burned.
The pressing equipment has access to areas of a cd that any reader or burner cannot access.
In the case of PSX an authentification code is pressed into an area of the cd that is unreachable by readers/burners.
The modchip fools the PSX into thinking it has accessed that unreachable data.
