Abstract
A small, high-precision, and cheap flying recording head having high mass-productivity, high recording density, and high transfer rate, a disk drive, and a method of manufacturing the flying recording head are disclosed. The flying recording head is manufactured by forming a semiconductor laser oscillation region by growing a semiconductor crystal on a rear end surface of a substrate made of a single crystal such as sapphire, and forming a air bearing surface in an output surface of the semiconductor laser and the substrate.
