Abstract
A thermal-assisted magnetic recording head which heats a magnetic bit of a magnetic disk by light radiation in recording magnetic data into the magnetic disk with a magnetic writing element. The magnetic recording head has a reflecting converging element with a surface emitting laser incorporated therein, and a transparent plate serving as a slider. A laser beam emitted from the surface emitting laser is reflected by a mirror surface of the reflecting converging element and is converged on a plasmon probe formed on a bottom surface of the transparent plate. Thereby, near-field light effuses from the plasmon probe into a very small area and heats the magnetic bit of the magnetic disk.
