Abstract
A pliant magnetic disc recording assembly having two adjacent transducer heads, with the center lines of the heads oriented at an angle to the axis of rotation of the magnetic disc and arcuately spaced with respect to such axis of rotation. The bearing surface of each head has a radius, and each bearing surface extends into the plane of the disc, whereby the disc has a wavy contour over the heads. The orientation, position and shape of the heads causes the disc to have a large wrap angle about each head whereby wear producing forces are distributed over a large area of the disc which lowers stresses on the disc.
