摘要： A magnetic recording and/or reproducing element comprises a main element body, and windings wound around the main element body. The main element body has a pair of extremely thin layers made from a ferromagnetic material, and the extremely thin layers oppose each other at respective edges thereof so as to constitute a gap. Each of the thin layers are sandwiched between a pair of support members which are made from a non-magnetic and abrasion proof material. A contact surface is formed on a vertex part of the main element body, for making contact with a magnetic recording medium so as to record and/or reproduce a signal on and/or from the magnetic recording medium. The main element body has one or a plurality of side surfaces which form a predetermined angle with respect to the contact surface and define the peripheral edge of the contact surface so that the contact surface has a predetermined shape with an extremely small area and has the gap at an approximate center of the predetermined shape.
