Abstract

PURPOSE:To improve the recording density by forming a gap of each magnetic head while being projected from a slide face with a medium and forming a recess to a part of the slide face opposed to a gap of other magnetic head. CONSTITUTION:The gap 22 of the magnetic core 21 imbedded and fixed to the slider 23 is formed onto the magnetic head 20 while being projected by a height (d) from the medium slide face 24 of the slider 23. A slot 25 is formed to nearly the center of the slide face 24 along the rotating direction of a floppy disk 2 or and disk moving direction (direction of arrow R). Furthermore, a recess being an escape to the projecting gap is provided to a part where the gap of other magnetic head arranged oppositely in pairs with the head 20 in the slide face 24 is provided continuously to the slot 25 to form a notch 26. Thus, the spacing due to the effect of the dynamic pressure of air is avoided to improve the head contactness to a recording medium such as the floppy disk thereby attaining high density recording.
