Abstract

PURPOSE:To set the mutual size with high accuracy by forming an element determining the relative size of a drive section of a floppy disk device to a stator base integrally by the out-sert method. CONSTITUTION:The drive section of a floppy disk device 1 has a stator base assembly 5 provided with a spindle motor having a hub 2-a and a linear motor 3 whose magnetic head 4 is loaded to a moving device 3-a. The stator base assembly 5 is provided with bearing housings 5-a, 5-b, a projection 5-c deciding the height of the medium, a projection 5-d deciding the planer position and the height of the medium, a linear motor mount face 5-e deciding the height of the linear motor 3 and a fall-off preventing wall 5-f preventing the rotor 3-a of the linear motor 3 from being prevented against the drop shock on the way of handling or transportation integrally to its stator base 5 by the out-sert method. Thus, high accuracy is obtained to lots of relative positions by the assembling process.
