| Abstract(in English) | A front-yoke stacked-type TMR(Tunneling MagnetoResistive) head has an advantage of power noise with a large size of the TMR element.The head has a symmetrical structure to the element, and produces Lorentizan waveforms without any distortion in combination with perpendicular magnetic recording media.Therefore, a conventional signal processor is applicable to the head.However, there is a crucial issue of crosstalk from adjacent tracks.This paper describes the design and performance of the front-yoke stacked-type TMR head.Three-dimensional magnetic field calculations of some read-out characteristics were carried out, and it was found that an effective method to increase signal output and decrease crosstalk from adjacent tracks. |
