ABSTRACT:
To stabilize the transducing head of a magnetic disc memory apparatus, the head is mounted on a flexible leaf aligned transverse to the disc radius; the upstream leaf end is fixed to the head carriage, and the downstream leaf end is restrained against motion normal to the disc surface. The head is secured at a point on the leaf where the tangent to the leaf is always parallel to the disc surface; the head may be balanced on both sides of the leaf; and the leaf may be formed of two parallel members with torsional vibration damping material therebetween.
