MAGNETIC HEADS |
| 摘要 |
A magnetic head for a magnetic recording and playback device includes a core having two core parts which are spaced from each other and between which a transducing gap is formed. The core consists of a (preferably monocrystalline) zinc-ferrous ferrite. A preferred range of compositions is defined by the formula ZnaFe1-aIIFe2IIIO4, wherein 0.1</=a</=0.4. The Zn-ferrous ferrite may further comprise additions of CoII. |
