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 | lambda 111|+2x10-6</=| lambda 100|, the crystal orientation is in the range of a solid angle of 3xsin theta xcos phi which satisfies 0</= theta <10 degrees and 0</= phi </=360 degrees around [111], and in the case of | lambda 111|>/=| lambda 100|+2x10-6, the crystal orientation is in the range of a solid angle of sin theta xcos phi which satisfies 0</= theta <10 degrees and 0</= phi </=360 degrees around [100], where lambda 111 and lambda 100 respectively represent linear magnetostriction constant of the monocrystal magnetic material in directions <111> and <100>. The monocrystal magnetic material is a monocrystal MnZn ferrite whose chemical composition is represented by 20</=MnO</=40, 10</=ZnO</=25 50</=Fe2O3</=65 in terms of mol. %.
