Description
technical field [0001] The invention relates to an information recording disk drive unit, in particular to a magnetic strip for forming a magnetic head and a manufacturing method of the magnetic head. Background technique [0002] Perpendicular magnetic recording is a promising recording technique for recording magnetic data on magnetic disks, where the magnetic moment is perpendicular to the plane of the disk. The progression from longitudinal magnetic recording to perpendicular magnetic recording will drive ever-increasing data densities on magnetic disks in the future. [0003] A magnetic head employing a perpendicular recording method includes a thin film coil generating magnetic flux and a magnetic pole layer extending from the rear of an air bearing surface and emitting the magnetic flux generated by the thin film coil to a recording medium. The magnetic pole layer includes, for example, a track width defining portion including a width (unified width) defining a recor...
