CD player

Hello,
I can plug a USB stick in my HT amplifier and play any audio (or video) files with it: no brainer.
I thought that nowadays I could purchase an external USB CD/DVD drive which would present the disc content as files, as if they were on a stick.
However I made some google searches and could not find anything like that.
Is this at all possible? Any suggestions?
