In order to simplify the adjusting of a device for adjusting of sound head platforms for sound records, cassette sound recorders or digital storage devices which comprise a transport shaft, a sound head platform, a support for supporting the sound head platform and a sound head, a pivot bearing as well as a knife edge bearing are disposed successively in a radial plane to the transport shaft on the support which supports the sound head platform, the sound head platform is supported on the knife edge bearing and on the pivot bearing in direction and beneath the sound head main axis and is pushed against the pivot bearing and the knife edge bearing by a spring perpendicular with respect to the sound head platform and by at least one bearing axis formed by the pivot bearing and the knife edge bearing at a perpendicular distance, whereby the associated counter bearing for the spring is disposed about symmetrically with respect to the sound head main axis.
