PURPOSE:To prevent track shift, by supporting one magnetic head freely rotatably with an orthogonal rotary center shaft, and the other magnetic head with the rotary center shaft prolonged in the radial direction of a disc freely rotatably. CONSTITUTION:One magnetic head 5 in contact on one major plane of a magnetic disc 1 and the other magnetic head 7 in contact with the other main plane of the disc 1 are provided. A pair of magnetic heads 5, 7 arranged opposingly have conversion gaps 6, 8 respectively and the gaps 6, 8 are detacted mutually to avoid mutual interference. The one magnetic head 5 is supported with a gimbal with one spring support sheet 9 made of a phosphorus bronz having a spring property and the sheet 9 is fixed to a rotating arm 10. |
