摘要： A thin film magnetic head includes a recording pole layer that is divided into a tip portion, a wide rear portion, a flare portion, and a yoke portion as viewed from the air bearing surface (ABS). The tip portion and the wide rear portion directly contact a write gap layer. Part of the wide rear portion has a greater width that the tip portion. The wide rear portion is provided between the tip portion and the flare portion to reduce magnetic reluctance. Accordingly, it is possible to improve the pattern accuracy of the tip portion width by providing the flare portion, which reflects a large quantity of light, far from the ABS, while preventing an increase of the magnetic reluctance.

摘要： To prevent the high-frequency characteristic from deteriorating due to a narrow track. A thin-film magnetic head of the present invention is produced by forming a lower shielding layer, a read gap layer holding an MR magnetosensitive element facing to an ABS plane, a shared pole layer serving as an upper shielding layer and a lower pole layer, and a write gap layer laminated in order on an insulating substrate, by forming a first flattening layer, a coil pattern layer, and a second flattening layer laminated in order on the write gap layer excluding the vicinity of the ABS plane, and by forming an upper pole layer on the write gap layer and second flattening layer nearby the ABS plane. Because magnetic easy axis of the upper pole layer along the ABS plane is oriented in the thickness direction of the upper pole layer, the high-frequency characteristic in the magnetization rotation mode is obtained.
