A head arm mounting device for one or more scanning heads in recording/playback apparatus for disk records, especially flexible magnetic disks, includes a pivot shaft for the head arm, this shaft being held in a mount, with the aid of spring means, in a manner such that it has no axial play, and producing, in conjunction with the head arm loading spring, a head loading force which is constant and essentially independent of the head arm deflection. The mounting device consists essentially of a mount and a pivot shaft, either of which may be associated with a spring. A one-piece frame-shaped member with an integral spring constitutes an optimum mount. In an advantageous embodiment, means are provided for finely adjusting the force exerted by the head arm loading spring, and for compensating for tolerances in the spring force of the loading spring in the quantity production of disk drive apparatus. |
