摘要： A magnetic read/write head is produced with an insert layer between the substrate and the magnetic transducer. The insert layer has a lower coefficient of thermal expansion than the substrate, which reduces the temperature pole tip recession (T-PTR) of the head because the insert layer is an intervening layer between the substrate and magnetic transducer. The insert layer is produced by plating, e.g., an Invar layer over the substrate prior to fabricating the magnetic transducer. The Invar layer is annealed and the structure planarized prior to depositing a non-magnetic gap layer followed by the fabrication of the magnetic transducer.

摘要： A thin film magnetic head is provided. The thin film magnetic head includes an upper coil wire group and a lower coil wire group. Two columns of coil contact groups that are formed on both end portions of individual coil wires of the upper coil wire group and the lower coil wire group, connect both end portions of the coil wires. An insulating resist layer buries a space between coil contacts of the coil contact groups. An inorganic insulating layer buries a space between the two columns of coil contact groups. The upper coil wire group, the lower coil wire group, and the two columns of coil contact groups form a thin film coil that applies a magnetic recording field to the magnetic material layer. The insulating resist layer and the inorganic insulating layer are located at the same lamination height as the two columns of coil contact groups.

摘要： A write shield layer that forms a part of a thin-film magnetic head is set with respect to the widthwise full length W thereof lying substantially on an air bearing surface that is opposite to the recording medium such that when the full length W is trisected, the maximum thickness H1/3side thereof in a range of widthwise ⅓W size positioned at both ends thereof is larger than the average thickness Hm of the whole write shield layer from the air bearing surface up to the rear (H1/3side>Hm), so that the so-called external magnetic field resistance is improved, and inadvertent erasure of the information already recorded in the recording medium is avoided as much as possible. Besides, the PTP (pole tip protrusion) phenomenon arising from the generation of heat from coils, and external temperature changes can be held back.

摘要： In a storage medium to which information is recorded by using a write head of an inductive type, in addition to a servo section in which servo information is recorded and a data section to which data is to be written, a write training section on which training write of pseudo-data is to be performed is disposed on a recording track. When the temperature is low, a write control unit writes the pseudo-data to the write training area and then writes data to the data area. By writing the pseudo-data to the write training area, a write core is heated and caused to project toward the medium surface side by thermal expansion, and the writing ability is enhanced; then, the data is written to the data section. A write training section is also disposed in front of a data section in a track of a system area of the storage medium, and, when the temperature is low, and when system information is to be written to the data section of the system area, pseudo-data is written to the write training section.
