Abstract:
A magnetic head device comprising:a flexible disc;magnetic heads arranged at both surfaces of said disc so as to perform either a recording or a reproducing of data while said magnetic heads are being slidably brought into contact with the disc surfaces;a pair of arms capable of being moved up and down and supporting each of said magnetic heads at their extremity ends and realizing a biasing force for resiliently pressing said magnetic heads against the disc; anda supporting member for supporting a base end of each of said arms,wherein there is provided a height adjusting apparatus for adjusting the position of at least one of said arms in an upward or downward direction so as to alter the distance or biasing force between the magnetic heads and the disc, said height adjusting apparatus comprising a reinforcing leaf spring having a base end that is supported by said supporting member and an extremity end that is abutted against a surface of said arm, said height adjusting apparatus further comprising an adjusting screw connecting the reinforcing leaf spring to the support member, wherein the adjusting screw is turned to change the resilient force of the reinforcing leaf spring.
