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： In an optical information storage medium reproduction apparatus (10) for reproducing an optical information storage medium including a plurality of information recording layers each including a recording mark having a length shorter than an optical system resolution limit, reproduction laser power for reading an information recording layer closest to a reproduction-laser-incident surface of the optical information storage medium is set to be lower than reproduction laser power for reading an information recording layer farthest from the reproduction-laser-incident surface but not lower than minimum reproduction laser power that satisfies a reproduction signal characteristic that the optical information storage medium reproduction apparatus (10) requires. With the arrangement, it is possible to prevent that the information recording layer closest to the reproduction-laser-incident surface is irradiated wrongly with reproduction laser having high reproduction laser power, thereby making it possible to obtain successful reproduction quality. That is, it is possible to realize the optical information storage medium reproduction apparatus (10) that can set optimum reproduction laser power and perform stable super resolution reproduction.

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.
