Michael David Barrett -- who pled guilty to stalking ESPN's Erin Andrews back in December -- checked himself into prison this morning to begin serving his 30 month sentence.

Barrett was supposed to serve his time in Atwater, CA -- but instead checked into a prison in Atlanta.

Barrett was accused of secretly videotaping Andrews while she was naked in multiple hotel rooms.
