The thin-film magnetic-recording head includes: a read element; a write element; a non-magnetic insulating protective layer disposed around both read and write elements; a resist disposed at a position further away from an air-bearing surface than the read element; and, a hard-material member including a material selected from the group consisting of silicon carbide and tungsten, which is disposed at a position further away from the air-bearing surface than the read element and the write element. Both an end of the resist and an end of the hard-material member overlap the write element when viewed in a stacking direction. A ratio of a distance from the air-bearing surface to a deepest end of the hard-material member to a distance from the air-bearing surface to a deepest end of the resist is at least 0.9.

摘要： Embodiments of the present invention provide a perpendicular magnetic recording head suitable for high density recording that suppresses erasure after recording by reducing the remanent magnetization Mr of the main magnetic pole and thereby decreasing the squareness S. Accordingly to one embodiment, a main magnetic pole piece of a perpendicular magnetic recording head includes a FeCo ferromagnetic layer, into which a NiFe soft magnetic layer is inserted. Inserting the NiFe soft magnetic layer in a position in the FeCo ferromagnetic layer 1 to 7 mm away from a nonmagnetic layer allows a remanent magnetization Mr to be decreased without changing the number of layers of the nonmagnetic layer or a film thickness of the FeCo ferromagnetic layer. This helps suppress erasure after recording.
摘要翻译：本发明的实施例提供一种适用于高密度记录的垂直磁记录头，其通过降低主磁极的剩余磁化强度Mr而减小记录后的擦除，从而减小矩形度S.因此，在一个实施例中，主磁极片垂直磁记录头包括FeCo铁磁层，NiFe软磁性层插入其中。将NiFe软磁性层插入距离非磁性层1至7mm的FeCo铁磁层中的位置，可以在不改变非磁性层的层数或FeCo铁磁层的膜厚的情况下，使剩余磁化强度降低。这有助于在录制后抑制擦除。

摘要： To enable high density recording, improvements to the distribution of the magnetic field originating from a perpendicular recording magnetic head with a narrow track width, high resolution, and narrow erase width were made. According to one embodiment, a perpendicular recording magnetic head is provided with a write head which comprises a main pole layer, an auxiliary pole layer, a first subsidiary pole layer, a second subsidiary pole layer, a pedestal-like soft magnetic layer and a coil. Trailing and leading throat heights are controlled so as to make the trailing throat height shorter than the leading throat height wherein the trailing throat height is the throat height of the main pole layer's medium-tracking trailing side (top side as viewed in the film thickness direction) while the leading throat height is the throat height of the main pole layer's medium-tracking leading side (bottom side as viewed in the film thickness direction).
