Abstract

PURPOSE:To achieve uniform recording/playback characteristics and stable floating characteristics, by separating a floating plane into a plurality of channels and providing the floating surface at flowing in and -out sides. CONSTITUTION:A C type core 9 and a common part 9' of each channel are bonded so that a prescribed length of gap length can be provided with glass or the like to constitute a magnetic circuit. To reduce the floating height and to arrange air flow, a groove 11 in parallel with the rotating direction of a medium and a groove 10 orthogonal to the groove 11 are provided on the floating surface of the 9'. With the grooves 10, 11, a floating surface 8 at the flowing-in side and the floating surface 12 at flowing-out side are separated and located on the same track. Further, stable floating characteristics can be obtained by taking the lengths l1 and l2 of the floating surfaces 8, 12 as the same length.
