摘要： Multiple thin films of spin-valve GMR sensor are formed in a trapezoidal cross-sectional shape by laminating an antiferromagnetic layer, a pinned magnetic layer, a nonmagnetic conductive layer, a free magnetic layer and a nonmagnetic protective layer on a lower insulated gap layer. The amount of etching of the lower insulated gap layer produced in the process of patterning the spin-valve giant magnetoresistive layers into the multiple thin films of spin-valve GMR sensor is 10 nm or less. Further, the angle &thgr; which the tangent line of each side face of the multiple thin films to the middle line of the free magnetic layer in its thickness direction forms with respect to the middle line of the free magnetic layer becomes 45 degrees or more. This structure makes it possible to provide such a spin-valve giant magnetoresistive head that it meets the requirements for securing constant breakdown voltage and preventing instability of MR output voltage waveform.

摘要： Even if the track and gap widths are made narrow in a read head, a narrow track head has so far been unable to afford satisfactory off-track characteristics because of a wide shield spacing over electrodes. The invention provides a magnetic head wherein, in the height direction of a magnetoresistive element, the spacing between an upper magnetic shield and a lower magnetic shield at an air bearing surface is narrower than the spacing between the upper and lower magnetic shields formed over a thickest portion of each of electrodes in contact with associated magnetic domain control layers.

摘要： Embodiments of the present invention prevent a pinned layer from suffering magnetization reversal by external stress in a magnetic head of magnetoresistance effect type which has a synthetic ferri-magnetic pinned layer structure with an antiferromagnetic layer of IrMnCr. According to one embodiment, a read element of a magnetoresistive head is made up of a antiferromagnetic layer, a first pinned layer, an antiferromagnetically coupled layer 4, a second pinned layer, and a free layer, which are stacked one over another. The first and second pinned layers and have a composition of Co75Fe25 and Co95Fe5, respectively, and a thickness of 18 Å (3.5 nm·T) and 21 Å (3.9 nm·T), respectively, so as to reduce the difference in anisotropic energy between the first pinned layer in contact with the antiferromagnetic layer and the second pinned layer in contact with the nonmagnetic conductive layer. In this way it is possible to reduce the difference |λ1−λ2| in magnetostriction constant between the first and second pinned layers and below 5.0×10−6. Thus it is possible to protect the pinned layer from external stress and magnetic field which rotate the direction of magnetization.
