Abstract
A flexible magnetic recording disc is brought into transducing relation with a recording head by moving a pressure pad against the disc from the side thereof opposite the recording head, and at a point upstream from the latter, in the direction of disc rotation. This resiliently flexes the disc and deviates part of it from its plane of revolution, causing it to partially wrap over the face of the head, in close transducing proximity, without the requirement of a pressure pad on the disc directly opposite the recording head, leaving that area open for other components. In a preferred embodiment, a separate transducing head is used on each side of the flexible disc, in direct alignment with one another, with a similarly-positioned pair of pressure pads disposed upstream, and all are mounted for articulating movement laterally toward and away from the plane of the disc. Means are provided to prevent simultaneous articulation of both such heads toward one another, to preclude crashing the heads against one another through the recording disc disposed therebetween.
