Abstract
PURPOSE:To prevent the reduction in a performance by dividing an arm supporting block into the inner side structure held on a spindle shaft via a bearing and the outer side structure supporting the arm of a magnetic head, integrating a filling cushion material by fixing by interposing it and equalizing the thermal expansion coefft. of the inner side structure and bearing. CONSTITUTION:A male screw is provided on the outer face of a cylindrical bush 4 and a female screw on the inner face of an arm supporting block cylinder 5, integrating them by interposing an adhesive and a block 5 is supported on a shaft 8 by bearings 1 and 6. The bearing 6 is taken for an inner wheel press fitting and outer wheel adhesion, and the bearing 1 for inner wheel press fitting and outer wheel loosely fit and a radial pre-load is exerted by a spring 7. A thrust pre-load spring 3 and bearing spacer 2 are provided further. With this constitution the linear expansion coefft. of the shaft 8, bearing 1 and bush 4 are equal, the adhesive becomes of a cushioning material and a pre-load is exerted on the bearing, hence the inclination of a head axial line is kept constantly and there is no reduction in the R/W performance of the device due to temp. variation.
