<P>PROBLEM TO BE SOLVED: To provide a heat-assisted magnetic recording apparatus having stable sliding reliability by solving the following problem: since a magnetic disk is irradiated with near-field light by a head and a magnetic film is heated to nearly 250°C in heat-assisted magnetic recording, a lubricant film on a disk surface is reduced by evaporation and thermal decomposition and a risk in which sliding reliability between a head and a disk is suddenly reduced and by reducing reduction of the lubricant film. Ž<P>SOLUTION: A fan-shaped flat plate impregnated or coated with a lubricant is provided on a surface opposed to the magnetic disk, the lubricant film reduced by local heating in the heat-assisted recording is repaired and a gas flow is made to forcibly flow to a disk-facing surface to cool the disk surface. Thus, reduction of the lubricant film on the magnetic disk surface is reduced and the heat-assisted magnetic recording device having stable sliding reliability is obtained.
