英文摘要	In a head for thermal assisted magnetic recording device, a semiconductor laser is mounted so that the total height of the head does not become larger and light power fluctuation due to wavelength fluctuation occurs less frequently. In addition, the rise in temperature of the mounted semiconductor laser is suppressed. A semiconductor laser is placed on a side surface which is different from surfaces on an inflow end side and a trailing side, of four side surfaces of a floating slider. An entrance of a waveguide is placed on the side surface of the floating slider, to thereby cause emitted light from the semiconductor laser to directly enter the waveguide. A curved line part or a reflective mirror is formed in the middle of the waveguide so that the light which has entered the waveguide travels toward an optical near-field generating element.
