摘要： PROBLEM TO BE SOLVED: To provide a thermally assisted information recording device which satisfactorily records magnetic information on a recording medium.
SOLUTION: A first slider part has a function as an optical head which irradiates an opposite first recording surface with light and a function as a magnetic head which reads and writes the magnetic information recorded on the opposite first recording surface. A diffraction grating 21a is provided so as to adjacently oppose the laser-assisting part of a first arm part and has a plurality of nearly sawtooth-shaped grooves. The plurality of grooves are formed of a material similar to a body 21b. On the surface of each groove, a reflective film 21c and an insulating film 21d are laminated in this order from the body 21b toward the laser assisting part. Namely, the surface of the diffraction grating 21a is coated with an insulating substance to serve as an insulator. This prevents the occurrence of short-circuiting between electrodes, an FPC and a metallic ball, and a first optical element 21.

摘要： PROBLEM TO BE SOLVED: To provide a method that facilitates manufacturing a diffraction grating resistant to a temperature change.
SOLUTION: A silicon type solution having a ladder-type crosslinking reactivity is applied onto a rugged surface of a prescribed mother mold 1 to form an SOG solution layer 2 on the rugged surface. A substrate 3 is placed on the SOG solution layer 2, thereafter, a solvent of the SOG solution layer 2 is vaporized and, at the same time, the ladder-type crosslinking reaction is caused in the SOG solution layer 2 to solidify the SOG solution layer 2. Thereby, the SOG solution layer 2 is changed into a diffraction pattern layer 12 having a rugged surface complementary to the rugged surface of the mother mold 1 and a composite material 10 made by adhering the diffraction pattern layer 12 onto the substrate 3 is provided. The composite material 10 is stripped from the mother mold 1 and the diffraction grating is obtained. By using the silicon type solution having a ladder-type crosslinking reactivity, the diffraction grating resistant to a temperature change like a glass product can be easily manufactured.
