How to make 1:1 copy of disk ignoring index files

Not sure how to describe this but here goes.
I know that file systems use index files to point to files but is there a way to ignore them in copying a disk? So that every single bit is read and recorded? I know that the dvd I'm copying has more data on it so is there a way to just record and write the bits? So far I've tried

Code:

dd if=/dev/cdrom of=~/test.iso

And gotten a 198MB output. On a disk with GBs of data.

So I looked into dd and tried

Code:

dd if=/dev/cdrom of=~/test.iso iflag='noblock' iflag='nocache'

As I'm here you can probably tell it did the same thing but slower. So any way to just copy the entire disk 1:1?

Check the DVD for protection schemes? Because if it does use one then LQ is not the place to ask.
