PURPOSE:To stably keep the contact state of a main magnetic pole with a floppy disk, by using a part of an auxiliary magnetic pole as a pat. CONSTITUTION:The main magnetic pole is formed with a slider 101, and a main magnetic pole film 102. And the part 104 of an auxiliary magnetic pole 103 drives mainly the magnetic pole by a coil 105. The peripheral part of the part 104 of the auxiliary magnetic pole is formed so that its center part is lower than other parts, and is formed higher as separating from the part 104. A main magnetic pole 106 is brought into contact with a floppy disk 108 in such constitution. Additionally, since both end parts of an auxiliary magnetic pole 107 are brought into contact with the floppy disk 108, the plane shaking of the floppy disk can be suppressed, and its position is fixed. |
