PURPOSE:To simplify production process and achieve the improvement in the accuracy of working by integrally forming the respective housings of the spindle of a magnetic disc plate and the revolving shaft of an arm on a base plate. CONSTITUTION:Housings 4, 8 are suitably set at the axial center-to-center spacing L thereof so as to be precisely connected a magnetic head 5 to a magnetic disc plate 2 with accuracy and are integrally molded to a base plate 1 so as to suitably determine the serration 11 of the mounting parts 4a and 8a of the respective housings. The housing 4 supports a spindle 3 of the plate 2 rotatably in the vertical direction and the housing 8 supports the revolving shaft 7 of a revolving arm 6 supporting the head 5 rotatably in the vertical direction. This causes the head 5 to be slide contacted to the plate 2. |
