PURPOSE:To improve stability of a head touch by providing a pressure spring for pressing a rocking supporting arm for supporting one head B, and also a head load spring for pressing the head B itself, which is set more weakly than said spring. CONSTITUTION:A floppy disk is pushed in between both heads 25, 23, and when a bail descends, a rocking supporting arm 28 is pressed by a placing plate spring 30 and a head B33 also descends. The head B33 is pressed and made to contact with a head A25 through the floppy disk by pressure of a plate spring 35. Spring force of the plate spring 35 is smaller than spring force of the placing plate spring 30, influence of a load of the rocking supporting arm 28 is eliminated completely, and inertia is given to only the heads 25, 33 part and becomes small. Also, since the plate spring 35 exists, the load is not varied by its installation direction, and a head touch of the head B33 to the head A25 becomes stable. |
