If there is an error in binary data then the whole freaking file/installation or whatever would be screwed, but no, CD-ROMs read data just fine...so....why can't another machine read data and copy it....

As I told U, the reader manages to read data correctly thanks 2 EFM
redundancy - data is sort of like "repeated" on the CD, allowing reader's internal error correction to correct the data if the damage is not too great (minor scratches, etc...). However because of the necessity of this error correction AND because of the existence of fake errors part of some copy-protection schemes, 100% RAW
reading is impossible, for the reader will HAVE to "understand" to some extent what it is reading -
it is inevitable, Mr Anderson...

How do they do it at factories? I heard they like STAPLE an image onto a CD...

CD-ROMs have a metallic surface as far as I know
CD-Rs have a surface covered with a colored, non-metallic substance
In factories, they make CD-ROMs, not CD-Rs. Since CD-ROMs are metallic, they are "etched", or pressed: there are pits & lands, the pits are cut by powerful lasers.
But we - the average users - don't have CD-pressers, which are not sold on the market anyways. We use CD-Rs, and our CD-
burners burn black marks onto the colored surface of the CD-R. These black pecks simulate a CD-ROM's pit. Besides, unlike factory CD-pressers, our burners' lasers are not strong enough to cut a pit into the metallic surface of a CD-ROM, so it would be pointless to buy blank CD-ROMs, if these were 2 B found on the market...
