Abstract: 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.<10 degrees and 0.ltoreq..phi..ltoreq.360 degrees around [111], and in the case of .vertline..lambda..sub.111 .vertline..gtoreq..vertline..lambda..sub.100 .vertline.+2.times.10.sup.-6, the crystal orientation is in the range of a solid angle of sin .theta..multidot.cos.phi. which satisfies 0.ltoreq..theta.<10 degrees and 0.ltoreq..phi..ltoreq.

Abstract: A non-magnetic substrate material which contains 0.5%-3% of Al.sub.2 O.sub.3 and 3%-16% of at least either ZnO or SnO.sub.2 (but with ZnO+SnO.sub.2 <=16%) in addition to components of 45%-60% of TiO.sub.2, 5%-20% of BaO and 20%-35% of CaO, and a floating-type magnetic head with a slider made of the above-mentioned non-magnetic substrate material.
