摘要: In a floating magnetic head, noises produced at the time of reproduction are reduced, thereby enhancing the precision of detection of a track position. The floating magnetic head uses a monocrystal magnetic material constituting an electromagnetic transducer element, and a crystal orientation of the monocrystal magnetic material in the electromagnetic transducer element is parallel to a direction of travel of a medium. In the case of .vertline..lambda..sub.111 .vertline.+2.times.10.sup.-6 .ltoreq..vertline..lambda..sub.100 .vertline., the crystal orientation is in the range of a solid angle of 3.multidot.sin.theta..multidot.cos.phi. which satisfies 0.ltoreq..theta. and . The monocrystal magnetic material is a monocrystal MnZn ferrite whose chemical composition is represented by 20.ltoreq.MnO.ltoreq.40, 10.ltoreq.ZnO.ltoreq.25 50.ltoreq.Fe.sub.2 O.sub.3 .ltoreq.65 in terms of mol. %.
