摘要： PROBLEM TO BE SOLVED: To provide a magnetic head device having structure capable of suppressing ESD damage and fully protecting a CPP type playback head from noise by a recording head, etc. SOLUTION: The magnetic head device is constituted by providing a short-circuit mechanism 3 between a grounded substrate 20 and a laminated film pattern 12A, electrically connecting each of a magnetic pole layer 18, a lower shield layer 10 and an upper shield layer 8 in a recording head with the substrate 20 and adjusting all the capacitances C28-C30 among those so as to be equal. Thus, electrostatic charges generated in manufacturing or use and accumulated in the laminated film pattern 12A, the magnetic layer 18, the lower shield layer 10 and the upper shield layer 8, etc. are gradually discharged and as a result, the ESD damage is suppressed. Moreover, an influence to an operation of the laminated film pattern 12A by the noise and cross-talk caused by the recording head is also prevented. COPYRIGHT: (C)2006,JPO&NCIPI

摘要： PROBLEM TO BE SOLVED: To provide a magnetic reproducing and recording head for improving magnetic stability of a shield layer.

Since the FM layer S2a-1 and the FM sub layer 16, and the FM sub layer 18 and the FM layer S2a-2, are antiferromagnetically coupled via the AFCT layer 17 by the AFM layer 19, the magnetic domain of the composite upper shield layer S2p is stably and strongly fixed.

摘要： PROBLEM TO BE SOLVED: To provide a vertical magnetic recording head capable of suppressing adjacent track erasure by making a magnetic flux flow between side shields and a trailing shield smooth.
SOLUTION: In the vertical magnetic recording head provided with magnetic shields 30 surrounding a magnetic pole tip part 16A from three directions, the magnetic shields 30 are formed by forming a pair of side shields 30A integrally with the trailing shield 30B. Since joining surfaces are not generated between the side shields 30A and the trailing shield 30B, the magnetic flux flow therebetween is not impeded. Since intensity of a fringe magnetic field is reduced, adjacent track erasure is suppressed.

摘要： PROBLEM TO BE SOLVED: To provide a perpendicular magnetic recording head improving recording performance by suppressing saturation of magnetic fluxes in a trailing shield. SOLUTION: The perpendicular magnetic recording head includes: a tapered main pole layer 21 having a slope 21s, a tapered non-magnetic top-shaping layer 22 having a slope 22s positioned in the same plane as the slope 21s, a recording gap layer 23, and a trailing shield 24, which are stacked in this order. Since the tapered main pole layer 21 has a tapered portion, intensity of a recording magnetic field is increased. Since the tapered non-magnetic top-shaping layer 22 is inserted between the trailing shield 24 and the tapered main pole layer 21, saturation of magnetic fluxes in the trailing shield 24 is prevented. Since both the tapered main pole layer 21 and the tapered non-magnetic top-shaping layer 22 have tapered portions, effective throat height is easily controlled more than when there is no tapered portion.

摘要翻译：要解决的问题：提供垂直磁记录头，通过抑制后挡板中的磁通量的饱和度来改善记录性能。解决方案：垂直磁记录头包括：具有斜面21s的锥形主极层21，具有位于与斜面21s相同的平面中的斜面22s的锥形非磁性顶部成形层22，记录间隙层23和后挡板24，其按顺序堆叠。由于锥形主极层21具有锥形部分，所以记录磁场的强度增加。由于锥形非磁性顶部成形层22插入在后屏蔽件24和锥形主极层21之间，所以防止尾部屏蔽件24中的磁通量的饱和。由于锥形主极层21和锥形非磁性顶部成形层22都具有锥形部分，所以与没有锥形部分相比，有效喉部高度容易受到控制。版权所有（C）2009，JPO＆INPIT

摘要： PROBLEM TO BE SOLVED: To provide a TAMR (Thermal Assisted Magnetic Recording) head for high-density recording. SOLUTION: The TAMR head includes a main magnetic pole, a plasmon antenna 22 including a core 24 formed of a magnetic material and a clad 27 formed of a non-magnetic conductive material, and an optical waveguide 23 that guides electromagnetic radiation from a light source to the plasmon antenna 22 to be coupled to a plasmon mode. The plasmon antenna 22 forms and maintains the plasmon mode therein, and also transfers energy generated in the plasmon mode to a local part of a magnetic recording medium to heat it, thereby reducing a coercive force and magnetic anisotropy. The intensity and gradient of the recording magnetic field in the heat spot on the magnetic medium are coupled to a profile of the heat energy of the plasmon mode to form an optimal situation for write operation.

摘要： PROBLEM TO BE SOLVED: To provide a magnetic reproducing head provided with a CCP-CPP type GMR element with high current carrying capability by incorporating a thermoelectric cooling structure, and to provide its method of manufacturing the same and a cooling method permitting the effective cooling of a particulate layer.
SOLUTION: A negative thermoelectric potential material is used for layers from a cap layer 27 to a free layer 26 and an upper conductive layer 25b in a non-magnetic particulate layer 25. A positive thermoelectric potential material is used for the layers from the lower conductive layer 25a in the non-magnetic spacer layer 25 to a pinned layer 24, an antiferromagnetic layer 22, and a seed layer (not illustrated). An electric current is passed from the upper conductive lead layer S2 to the pinned layer 24, the antiferromagnetic layer 22 and the lower conductive lead layer S1 through the cap layer 27, the free layer 26, the non-magnetic spacer layer 25. A thermoelectric cooling effect is developed, and the non-magnetic spacer layer 25 covering the large part of heat generation by electric current is locally cooled down.

摘要： PROBLEM TO BE SOLVED: To provide a magnetic recording head in which occurrence of erasing an adjacent track can be suppressed. SOLUTION: A lower part magnetic pole 50 is constituted so as to include a front part 12 and a rear part 17 (having different thickness, rectangle type pillar 51) constituting a step (difference in level), and especially, the rear part 17 is made nearer to an upper part magnetic pole 54 than the front part 12. As magnetic resistance is reduced between the upper part magnetic pole 54 and the lower part magnetic pole 50, surplus magnetic fluxes generated when a recording current is set largely is absorbed in a magnetic flux expansion body 53 without leaking to a side of a recording gap 15. Thereby, as magnetic fluxes become hard to leak at the vicinity of a shoulder region of the lower part magnetic pole 50, strength of a needless magnetic field generated at the vicinity of the shoulder region of the lower part magnetic pole 50 is made small.

摘要： PROBLEM TO BE SOLVED: To provide a side-shield structure capable of narrowing a recording track width during recording.
SOLUTION: The side-shield structure 200 provided adjacent to a main magnetic pole layer 35 includes: first-side shield portions 51 and 52 arranged facing side-surfaces 35b and 35c of a recording magnetic pole 35p; second-side shield portions 53 and 54 arranged facing a side-surface 35s of a flare portion 35f; a first non-magnetic gap layer 55 provided between the first side-shield portions 51 and 52 and the second shield portions 53 and 54; and a second non-magnetic gap layer 56 provided along the side-surfaces 35b and 35c of the recording magnetic pole 35p and the side-surface 35s of the flare portion 35f. Magnetic flux leaking through the flare portion 35f is captured by the side-shield portions 53 and 54, and thus the magnetic flux is less likely to reach the side shield portions 51 and 52.

摘要： PROBLEM TO BE SOLVED: To provide a PMR head capable of improving overwrite performance and an S/N ratio while suppressing an erasing phenomenon after a recording operation. SOLUTION: On a substrate, n magnetic layers 24a to 24d and n-1 nonmagnetic spacers 25a to 25c are alternately formed. The nonmagnetic spacer 25a or the like promotes exchange decoupling or antiferromagnetic coupling between adjacent magnetic layers. Writability is improved when the trailing magnetic layer 24d has a thickness greater than those of the other magnetic layers 24a to 24c (preferably, more than 25% of the total thickness of all the magnetic layers 24a to 24d). The thicknesses of the other magnetic layers 24a to 24c are equal or progressively smaller with increasing distance from the trailing magnetic layer 24d. Further, the nonmagnetic spacer 25c between the trailing magnetic layer 24c and its adjacent magnetic layer 24c is replaced by a magnetic spacer made of a soft magnetic material to effectively increase the substantial thickness of the trailing magnetic layer 24d.
