THIS INVENTION RELATES TO A MAGNETIC HEAD DEVICE (21) AND A DISK DRIVE, WHICH ARE SUITABLE FOR APPLICATION TO A MASS-STORAGE FLOPPY DISK DRIVE OR THE LIKE. A FIRST AND A SECOND RAILS (26A, 26B) ARE PROVIDED ON THE DISK SIDE IN PROJECTED FORM ON A SLIDER (25) OF EACH OF MAGNETIC HEAD ELEMENTS (20) SO AS TO EXTEND IN A TANGENTIAL DIRECTION R OF A TRACK OF THE DISK AND BE PARALLEL WITH EACH OTHER. A HEAD CHIP FOR RECORDING AND REPRODUCING DATA IN A STATE OF BEING IN CONTACT WITH A RECORDING SURFACE OF THE DISK AND IN A STANDARD RECORDING DENSITY IS PROVIDED SUBSTANTIALLY IN THE CENTRAL POSITION OF THE FIRST RAIL. ANOTHER HEAD CHIP FOR RECORDING AND REPRODUCING DATA IN A. STATE OF BEING LEVITATED FROM THE RECORDING SURFACE OF THE DISK AND IN A HIGH RECORDING DENSITY IS PROVIDED IN A POSITION ON THE REAR SIDE OF THE SECOND RAIL (26B) WITH RESPECT TO THE TANGENTIAL DIRECTION R OF THE, TRACK. A WIDTH OF THE FIRST RAIL OF EACH MAGNETIC HEAD ELEMENT IS NARROWER THAN A WIDTH OF THE SECOND RAIL (26B) THEREOF. THE SLIDER (25) IS INCLINED AND LEVITATED SO THAT THE SECOND RAIL (26B) APPROACHES THE RECORDING OF THE DISK. THE MOST ILLUSTRATIVE DRAWINGS ARE (FIGURES 5,6, AND 9)
