PURPOSE:To contrive the improvement of a recording characteristic and an over-write characteristic by having magnetic anisotropy in a magnetic core so that a magnetizing easy direction of the magnetic core composed of magnetic alloy in which a regular lattice is produced is approximately in parallel to the sliding direction of a medium. CONSTITUTION:A magnetic head slides a magnetic core 1 on a magnetic recording medium to perform magnetic record or playback of a piece of information. At the time of core 1 is composed of magnetic alloy in which a regular lattice is produced. Magnetic anisotropy is allowed to have in the core 1 so that the magnetizing easy direction of the core 1 is approximately in parallel to the sliding direction of a magnetic recording medium. An alloy or at least two compounded alloys of an Fe-Co-Si system alloy, an Fe-Si-Al system alloy and an Fe-Si-Ni system alloy are used as a magnetic alloy. Thereby the improvement of a recording characteristic and an over-write characteristic can be contrived. |
