What is the name of the samurai with the best undefeated record?
Correct answer: Miyamoto Musashi

Mathom
The 1950's Samurai Trilogy directed by Hiroshi Inagaki is widely considered the best, most complete, historical drama of the life of Miyamoto Musashi and well worth a viewing if you can understand Japanese or are up to wading through the subtitles. Recommended.
Also, Musashi's Book of Five Rings is a quick read but very insightful, exploring his philosophy on the Way of the Warrior. While written as a martial text, his lessons can be interpreted and applied in our everyday lives.
