摘要： An electromagnetic field generating element includes a conductor that generates near-field light when irradiated with light and generates a magnetic field when a current flows through the conductor. The electromagnetic field generating element further includes a soft magnetic body provided at a position along a dimension of the conductor, the dimension being perpendicular to (i) a direction in which the conductor faces a magnetic recording medium to which the near-field light and the magnetic field are applied and to (ii) a direction in which the current flows. The present invention thus allows for provision of an electromagnetic field generating element that allows for reduction in its power consumption in optically assisted magnetic read/write using near-field light.

摘要： A magnetic recording medium (1a) includes: a plurality of magnetic dots (13), provided on a substrate (11), in each of which information is stored by heating of the magnetic body; and separator layers (50). Each of the separator layers (50) is structured such that a metallic body layer (52) and two dielectric body layers (51) are alternately stacked in an in-plane direction of the substrate (11). Each of the separator layers (50) separates two magnetic dots from each other in the in-plane direction. Both sides of each of the magnetic dots (13) in the in-plane direction of the substrate (11) have contact with two dielectric body layers (52), respectively. This provides a magnetic recording medium (1a) whose magnetic dots (13) can be entirely heated with a reduction in the amount of power that is consumed by a recording head.

Further provided are a buffer layer 8 which sandwiches the magnetic sensing section 7 with the buffer layer 3 and a biasing layer 10 which covers the right and left sides of the part constituted by the buffer layer 3, the magnetic sensing section 7, and the buffer layer 8 and which is deposited on the magnetic layer 2 with a nonconductor layer 9 being interposed therebetween. On that surface, a near field light generation section 14 is formed which is constituted by a magnetic layer 11, a dielectric layer 12, and a metal layer 13. With this, it is possible to obtain a magnetic sensor device which can efficiently perform photo-assisted reproduction of information from a magnetic recording medium, a magnetic reproduction head and a magnetic reproducer using the device, and a magnetic reproduction method of a magnetic recording medium, using the magnetic reproducer.
