摘要： A thin film magnetic head includes an upper magnetic pole maintaining a constant thickness in a range determined by the so-called gap depth. A thinner film portion is defined in the upper magnetic pole in a range rearward of the range determined by the gap depth. The thinner film portion has a reduced thickness smaller than the constant thickness. The upper magnetic pole starts to enlarge the core width in the lateral direction at the rear end of the region determined by the so-called neck height. The neck height smaller than the gap depth serves to establish a reduction in the thickness of the upper magnetic pole after the upper magnetic pole gets larger in the lateral direction. A magnetic saturation can reliably be prevented at the thinner film portion in the upper magnetic pole. The front end of the upper magnetic pole is allowed to receive a larger quantity of a magnetic flux. It is possible to reliably enhance a magnetic field for recordation in the thin film magnetic head.

摘要： A thin film magnetic head includes an upper and a lower magnetic pole layer extending forward from a central magnetic core within a thin film coil. A narrow upper and lower front magnetic pole piece are connected to the front ends of the upper and lower magnetic pole layer, respectively. The upper front magnetic pole piece extends rearward from its front end exposed at a medium-opposed surface. The lower front magnetic pole piece extends in a lateral direction along the medium-opposed surface by a lateral width larger than that of the upper front magnetic pole piece. The lower front magnetic pole piece extends rearward from the medium-opposed surface by a longitudinal length smaller than that of the upper front magnetic pole piece. The lower front magnetic pole piece serves to concentrate the magnetic flux at the front ends of the upper and lower front magnetic pole pieces. Since the lower front magnetic pole piece is designed to have a larger lateral width in the lateral direction irrespective of a smaller length in the longitudinal direction, the production of the lower front magnetic pole piece can remarkably be facilitated.

摘要： A liquid resist is introduced between adjacent conductive lines of a coil pattern girdling around a magnetic core piece. When the liquid resist is cured, an insulating resin filler can be fixed between the adjacent conductive lines of the coil pattern. An insulating metallic layer is formed to extend over the insulting resin filler and the conductive lines of the coil pattern. Thereafter, the insulating metallic layer is subjected to a flattening grinding treatment until at least a part of the conductive line is exposed at a flattened surface. Of the resist, of a higher fluidity, penetrates in every hole and corner between the adjacent conductive lines, the gap defined between the adjacent conductive lines is fully filled with the insulating material. No voids remain in the gap. The conductive line of the coil can be reliably prevented from corrosion or oxidation. Moreover, a relatively brittle of fragile insulating resin filler is reliably prevented from being subjected to the flattening.

摘要翻译：在围绕磁芯片的线圈图案的相邻导线之间引入液体抗蚀剂。当液体抗蚀剂固化时，可以在线圈图案的相邻导电线之间固定绝缘树脂填料。绝缘金属层形成为在绝缘树脂填料和线圈图案的导线上延伸。此后，对绝缘金属层进行平坦化研磨处理，直到导电线的至少一部分在平坦表面露出。由于具有较高流动性的抗蚀剂的液体渗透在相邻导电线之间的每个孔和拐角处，所以相邻导电线之间限定的间隙被绝缘材料完全充满。间隙中没有空隙。可以可靠地防止线圈的导线腐蚀或氧化。此外，可靠地防止相对脆弱的脆性绝缘树脂填料进行平坦化研磨处理。

摘要： A magnetic memory device comprises: a vertically magnetic recording medium; a probe formed of an electrically conductive as well as soft-magnetic material, a pointed end of the probe faces the magnetically recording medium across a gap; a magnetic flux detecting element for detecting a magnetic flux caught by the probe, where the magnetic flux is from a data recorded on the magnetically recording medium; a vertical controller for keeping the gap constant by the use of a tunnel current flowing via said gap into the probe while a voltage is applied across the gap; and a scan mechanism for scanning the probe along the magnetically recording medium. The magnetic memory device may further comprises an exciting coil for magnetizing the probe so as to write a data in the magnetically recording medium. The probe may be recessed from the scanning position when the probe is not in operation.

摘要： An upper auxiliary magnetic pole is formed in a space on a lower magnetic pole layer. A first insulating layer is then formed over the surface of the lower magnetic pole layer. The upper auxiliary magnetic pole is embedded within a swell formed on the surface of the first insulating layer. A second insulating layer is then formed over the surface of the first insulating layer. The second insulating layer has a property less abrasive than the first insulating layer. The second insulating layer is subjected to grinding over a wider area just after the swell has completely been removed. The abrasion can be suppressed at the thin film magnetic head in which the swell has been removed. The first insulating layer of a predetermined thickness reliably remains in each of the thin film magnetic heads on the wafer. An accurate adjustment of the thickness of the first insulating layer leads to a reliable establishment of a predetermined thickness in the upper auxiliary magnetic pole with less error.
