DISKETTE TYPE MEMORY CARD ADAPTER, MAGNETIC SENSOR THEREFOR MAGNETIC CORE, METHOD FOR MANUFACTURING THE MAGNETIC CORE |
摘要 |
<p>A magnetic core used in a magnetic sensor of a diskette type memory card adapter is manufactured by laminating a plurality of rapidly solidified alloy sheets and by punching the alloy laminate. This lamination is carried out with a hot-melt adhesive. A heat treatment is made at a temperature of 180 to 220 DEG C before the punching, or at a temperature of 180 to 540 DEG C after the punching. The direction of the length of the magnetic gap of the magnetic core is perpendicular to the direction of magnetic anisotropy of the sheets. <IMAGE> <IMAGE></p> |
