PURPOSE:To cause the mounting space of a disk circular board to be high density by arranging the UP-type and DN-type of a magnetic head to the positions of an inner zone and an outer zone in the opposite side of a central line, which goes through a spindle center and a pivot. CONSTITUTION:Heads 5 to face to the medium on an upper surface and a lower surface between disk circular boards 2 are respectively arranged in the both sides of the line which passes through the spindle center and a pivot 18 of a carriage 8. Then, a spring arm 11 and a supporting arm 6 are respectively arranged so that one head 5 can be positioned in an outer zone 16 when the other head 5 is in an inner zone 15 of the circular board 2. Thus, the space for one head is enough to the interval of the disk circular board 2 and the interval can be narrowed down. Then, the mounting space of the head 5 and disk circular board 2 can be caused to be the high density and storing capacity can be increased. |
