摘要： PROBLEM TO BE SOLVED: To provide a perpendicular magnetic recording head capable of increasing a recording density, suppressing the leakage of a magnetic flux in a side direction and preventing side write, and its manufacturing method. SOLUTION: The perpendicular magnetic recording (PMR) head has a pair of side shield layers 20, 20 on a substrate 5, and a trench 300 is provided between the side shield layers 20, 20. Inside the trench 300, a side gap layer 60, a seed layer 15 and a magnetic pole (main magnetic pole) 10 are embedded in the order from the side of the inclined side wall 25 and the bottom surface. The magnetic pole 10 is protected by an upper shield 40 at the upper part and by the side shield layers 20, 20 at the side part. The trench 300 has a wedge-shaped cross section and thus the magnetic pole 10 is formed into the same shape in a self-aligning manner. COPYRIGHT: (C)2007,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To provide a method for manufacturing a thin film magnetic head by which the short-circuit between coil conductors can be suppressed by a simple process and a part between the coil conductors can appropriately be filled with an insulating layer. SOLUTION: An inorganic insulating layer 11 is formed along at least the side wall surface 10c of each conductor part 10a of a lower coil layer 10, a part between the conductor parts 10a is filled with an organic insulating layer 12, and the upper surface 10b of the conductor part 10a, a magnetic pole part 7, and a connection layer 8 are polished together with the organic and the inorganic insulating layers 12 and to be on the same plane. During the polishing of the upper surface 10b of each conductor part 10a, the hard inorganic insulating layer 11 suppresses the slackening of each conductor part 10a caused by the polishing, and short-circuiting between the conductor parts 10a is properly prevented. By filling the part between the conductor parts 10a with the organic insulating layer 12, the part between the conductor parts 10a is properly filled without forming any cavities between the conductor parts 10a.

摘要： PROBLEM TO BE SOLVED: To provide a magnetic head device having structure capable of suppressing ESD damage and fully protecting a CPP type playback head from noise by a recording head, etc. SOLUTION: The magnetic head device is constituted by providing a short-circuit mechanism 3 between a grounded substrate 20 and a laminated film pattern 12A, electrically connecting each of a magnetic pole layer 18, a lower shield layer 10 and an upper shield layer 8 in a recording head with the substrate 20 and adjusting all the capacitances C28-C30 among those so as to be equal. Thus, electrostatic charges generated in manufacturing or use and accumulated in the laminated film pattern 12A, the magnetic layer 18, the lower shield layer 10 and the upper shield layer 8, etc. are gradually discharged and as a result, the ESD damage is suppressed. Moreover, an influence to an operation of the laminated film pattern 12A by the noise and cross-talk caused by the recording head is also prevented. COPYRIGHT: (C)2006,JPO&NCIPI

摘要： PROBLEM TO BE SOLVED: To provide a manufacturing method of a thin film magnetic head capable of easily making write track width narrower. SOLUTION: This manufacturing method of a thin film magnetic head comprises the steps for forming a first magnetic layer; eliminating both sides of the first magnetic layer in the direction of track width so as to leave behind a prescribed residual region of the first magnetic layer; forming an insulating layer around the residual region of the first magnetic layer; forming a gap layer made of nonmagnetic material; forming a second magnetic pole layer magnetically connected to a first magnetic pole; and patterning the second magnetic layer by etching using a mask. Consequently, the insulating layer is mainly exposed from a region even though the region comparatively far from the second magnetic layer in the gap layer is eliminated. COPYRIGHT: (C)2006,JPO&NCIPI

摘要： PROBLEM TO BE SOLVED: To provide a method of precisely manufacturing a magnetic head by easily maintaining the thickness within a predetermined limit for the components such as the magnetic pole layer. SOLUTION: A raised area 111b is formed on a 1st insulation layer 111 on the main magnetic pole 110 which is a magnetic pole layer, and a flat area 111c is formed surrounding the raised area 111b. A 2nd insulation layer 131 is formed on the flat area 111c. The 1st insulation layer 111 is scraped off at the above raised area 111b to expose the top surface 110c of the main magnetic pole 110, then the top surface 110c of the main magnetic pole 110 and the top surface 131a of the 2nd insulation layer 131 are flattened to obtain a same surface. The polishing amount can be precisely controlled by finishing the polishing using the 2nd insulation layer 131 as a marker. COPYRIGHT: (C)2005,JPO&NCIPI
