MAGNETIC TRANSDUCER HEAD |
摘要 |
<p>A magnetic transducer head wherein confronting surfaces of a pair of magnetic core parts comprised of a ferromagnetic oxide material are notched, and the notch defining surfaces have metallic ferromagnetic layers supported thereby. The method of physical vapor deposition as known per se is used for forming these layers. The transducer coupling gap of each magnetic head is defined by an aligned pair of pole piece layers formed from the deposited metallic ferromagnetic material. The pole piece layers are inclined at a preset angle with respect to the plane of the coupling gap, and have extensions formed of the deposited metallic ferromagnetic material presenting bend contours between the pole piece layers and the lateral sides of the core parts.</p> |
