摘要： In a recording and/or reproducing apparatus (1) having a reel drive device (35) with a drive shaft (46A) and with a disc-shaped drive member (47) made of a plastic and with drive teeth (48), and with a second magnetic circuit element (49), and with a third magnetic circuit element (50), which is connected to the drive member (47) by insert-molding of the third magnetic circuit element (50), the drive shaft (46A) is connected directly to the third magnetic circuit element (50) in a rotationally interlocked manner and the third magnetic circuit element (50) is formed by an element which is finished by means of a turning operation, and the third magnetic circuit element (50) is dimensioned in such a manner with respect to the drive member (47) that the third magnetic circuit element (50) is not subjected to any deformation by the drive member (47) made by insert-molding.
