Welcome to Apple Support Communities. We're users here, and don't speak for "Apple Inc."
Since OS X 10.7 "Lion", Recovery is not done with a CD/DVD.
There is 1) a hidden recovery partition on the internal hard drive or SSD, and 2) internet recovery is possible:
As you noted, there is no standard CD/DVD drive, so shipping a CD/DVD with such computers doesn't make a lot of economic sense.

There is system recovery on Mac hard drives, now, as well as Internet system recovery.
Apple and many third party Apple software developers no longer distribute its software or OS software on install CD or DVD discs any longer.
Software is distributed online over the Internet via downloads from the software developers' websites or more common, now, The Mac App Store.
