发明名称 NEAR-FIELD LIGHT USING HEAD AND INFORMATION RECORDING DEVICE
摘要 <P>PROBLEM TO BE SOLVED: To provide a near-field light using head whose head can easily be manufactured, and an information recording device having a near-field light using head. <P>SOLUTION: A near-field light using head for recording information by generating near-field light to heat a predetermined region of a medium and giving a magnetic field to the predetermined region includes: an optical waveguide having a path for propagating a luminous flux; and a tip 117 having an optical minute opening 118 formed at a position facing the predetermined region to generate near-field light by propagating a luminous flux emitted from the optical waveguide toward the optical minute opening 118 while focusing the luminous flux. The optical minute opening 118 is formed by a magnetic pole that gives a magnetic field to the predetermined region. <P>COPYRIGHT: (C)2013,JPO&INPIT
