摘要： PROBLEM TO BE SOLVED: To provide a magnetic head for vertical magnetic recording, capable of suppressing noise caused by a soft magnetic layer, and rectifying reduction in efficiency, and a magnetic storing/reproducing device using the same. SOLUTION: An angle made by a line connecting the center of the main magnetic pole of a recording head with the center of a return yoke and a line connecting the opposing end parts of the main magnetic pole and the return yoke with each other is set to θ1, an angle made by the line connecting the center of the main magnetic pole of the recording head with the center of the return yoke and a line connecting the center of the main magnetic pole of a reproducing head with the center of the return yoke is set to θ2, and the relation between these angles is set such that θ2>θ1. Thus the direction of magnetic flux flowing through a medium during recording and reproducing will not overlap that of a magnetic flux that flows during recording and, therefore, the problems of Barkhausen noise, generated when the direction of both magnetic fluxes overlap, reduction in reproduction efficiency, and the like are solved.

摘要： PROBLEM TO BE SOLVED: To provide a magneto-resistive head of a SV head type and a magnetic reproducing device which permit a higher output by mounting an SV element having a free magnetization layer which has low magnetic resistance, high sensitivity and high efficiency. SOLUTION: The free magnetization layer of the SV head is divided into a central part and an end part (side part) according to the product of Ms.t and the product of Ms.t of the end part is made larger than that of the central part. In order to increase the product of Ms.t of the end part, it is effective to make Ms of a soft magnetic layer used in the free magnetization layer higher or to increase the film thickness. Thereby, a signal magnetic field is efficiently guided from the end part into the central part and, even when the film thickness of the free magnetization layer is made thinner for the sensitization, the signal magnetic field can be introduced thereto.

摘要： PROBLEM TO BE SOLVED: To provide a magnetic head and a magnetic reproducing device which reduce cross talk from adjacent tracks generated in accordance with the track- narrowing for densification of recording, and allow high S/N. SOLUTION: This magnetic head has a specified constitution in which magnetic bias impressing means are disposed on both sides of a magnetic detecting part such as a magnetic yoke or a magnetic core and, thereby, only a soft magnetic layer on a recording track to be reproduced is surely saturated. As a signal recorded on a recording layer is reproduced while impressing the magnetic bias in the direction of track width, it can be prevented to uselessly saturate the soft magnetic layers on the adjacent recording tracks. As a result, the cross talk on reproducing is widely reduced and the reproducing of high resolution is realized.

摘要： PROBLEM TO BE SOLVED: To highly accurately form the magnetic gap having a narrow gap width almost perpendicular to a substrate surface without being limited by stepper accuracy or the like with respect to the magnetic head of a yoke type. SOLUTION: On a soft magnetic material layer 31, a first masking layer 32 corresponding to the shape of a first plane yoke 12 is formed. On it, a material layer provided with a film thickness equivalent to the magnetic gap and a second masking layer 34 are successively laminated and formed. After working is performed so as to allow the surfaces of the masking layers 32 and 34 to be a continuous flat surface, the material layer provided with the film thickness equivalent to the magnetic gap is selectively etched and removed. The soft magnetic material layer 31 is etched by using the remaining first and second masking layers 32 and 34, a recessed part 36 is formed and first and second plane yokes are formed. The magnetic gap 15 is buried and formed inside the recessed part 36. Or, after a projection part provided with a width equivalent to the magnetic gap is formed, the soft magnetic material layer is formed on both sides and the first and second plane yokes are formed.

摘要： PROBLEM TO BE SOLVED: To manufacture a thin film magnetic head having a narrow track structure in high-precision in which counter widths of the magnetic gap between a lower magnetic pole and an upper magnetic pole are made roughly the same after allowing the head to satisfy a satisfactory head characteristic and mass-productivity. SOLUTION: In manufacturing a thin film magnetic head in which an upper magnetic pole is formed on a lower magnetic pole 7 with a magnetic gap 12, at first, at least a protruding part 11 corresponding to a recording track is formed in the lower magnetic pole 7 and it becomes, for example, the top end part 11 of the lower magnetic pole. A non-magnetic material layer 13 is formed along the shape of the protruding part 11 of the lower magnetic pole 7. A flatening layer 21 is formed on the non- magnetic material layer 13. The non-magnetic material layer 13 is etched by making this flatening layer 21 a mask. Moreover, a recessing part 14 which is self-matched with the top end part (protruding part) 11 of the lower magnetic pole is formed in the non-magnetic material layer 13. A magnetic layer (the top part of the upper magnetic pole) becoming one part of the upper magnetic pole is formed in this recessing part 14.

The electromagnetic conversion part 22 is held by the first and second ceramic substrates 25, 26 from, for example, approximately the track width direction. The electromagnetic conversion part 22 has a yoke type reproducing section having at least a pair of magnetic cores intervened with a magnetic gap on the side of the surface facing the medium and a magneto-resistive element to which signal magnetic fluxes are lead from the magnetic recording medium via a pair of these magnetic cores.
