  • Patent number: 10121497
    Abstract: A magnetic recording head has a main magnetic pole that generates a recording magnetic field applied on a magnetic recording medium from an end surface that is one portion of an air bearing surface facing the magnetic recording medium; a trailing shield provided on the trailing side of the main magnetic pole with a write gap interposed therebetween; and a spin torque oscillator that is provided in the write gap to be interposed between the main magnetic pole and the trailing shield and that generates a magnetic field that exerts an interaction on the recording magnetic field applied on the magnetic recording medium.

  • Patent number: 6106893
    Abstract: A method for manufacturing an inductor element for noise suppression, including the steps of coating one surface of a supporting body with a paste comprising ferromagnetic particles and resin so as to form a sheet, forming a conductive line by printing a conductive paste on the sheet, and coating the conductive line with a paste including ferromagnetic particles and resin so as to cover the conductive line and form a core. Also included is a step of applying heat treatment under pressure. The ferromagnetic metal particles include iron particles having diameters that fall within a range of 0.01 .mu.m to 10 .mu.m, and a content of the ferromagnetic metal particles is within a range of 30 vol % to 70 vol %.
