摘要： An electromagnetic field detecting element 10 includes a lamination of three insulation layers 2, 3, and 4. The dielectric breakdown strength of the insulation layer 3 is greater than the dielectric breakdown strengths of insulation layers 2 and 4. The three insulation layers 2, 3, and 4 are disposed between a pair of electrodes 5 and 6. Boundaries 7 and 8 on both ends of an overlapping region of the opposing surfaces 5a and 6a in a Z direction are apart from the insulation layer 3 by thicknesses t1 and t3 of the insulation layers 2 and 4, respectively. Between the pair of electrodes 5 and 6, ballistic current paths interposing therebetween the insulation layer 3 are formed by applying, between the pair of electrodes 5 and 6, an electric field having a magnitude which causes dielectric breakdown in the insulation layers 2 and 4 while causing no dielectric breakdown in the insulation layer 3. Thus, it is possible to perform at a room temperature a highly efficient electromagnetic field detection utilizing AB effect or AC effect.

摘要： A magnetic storage medium includes a magnetic storage medium that exhibits a magnetic compensation temperature specified higher than room temperature to minimize effects of heat generated by a head using magneto-resistance effect. In a heat assisted recording and reproduction method using such a magnetic storage medium, during reproduction, the S/N ratio in a reproduction signal is enhanced by optimizing the bias current applied to the head using magneto-resistance effect. A magnetic storage medium and a heat assisted recording and reproduction method using such a magnetic storage medium whereby information is magnetically recorded and reproduced by heating a read-out domain are offered that enables signal reproduction with a good S/N ratio despite possible use of a head exhibiting magneto-resistance effect.

摘要： The present invention provides a magnetic signal reproducing device including heating means for locally heating a reproducing region of a magnetic recording medium, first reproducing means for reading magnetic information in the reproducing region in a first temperature state to obtain a first reproduced signal, second reproducing means for reading magnetic information in almost the same region as the reproducing region in a second temperature state which is different from the first temperature state to obtain a second reproduced signal, and correcting means for correcting the first reproduced signal based on the second reproduced signal to obtain an information reproducing signal representing information recorded in the reproducing region. According to this, even if a medium temperature in a non-heated region of the magnetic recording medium is shifted from a magnetization compensation point, a signal from the region is prevented from mixing into a reproducing signal.

摘要： A non-contact current censor includes a spin valve structure (2), an electrical unit (4) that applies a varying current to the spin valve structure (2), and a resistance reading unit that electrically reads out a resistance value of the spin valve structure (2). When a current-induced magnetic field is detected, a coercive force of a free layer (14) is configured to be larger than the current-induced magnetic field as a detection target, and the electrical unit (4) allows the magnetization directions of a pinned layer (12) and the free layer (14) to transition between a mutually parallel state and a mutually anti-parallel state by applying the current to the spin valve structure (2). The resistance reading unit (5) detects a threshold value corresponding to the transition.
