ABSTRACT:
A flexible magnetic disk is rotated at a relatively high speed to cause the disk to revolve substantially in a plane. A pair of elongate guides for the disk are mounted in a converging relation, which permits the guides to reside substantially along respective radii of the rotated disk. The guides penetrate the plane of the rotated disk substantially along the two radii, and therefore will deflect successive radial sectors of the disk from the plane as each of the sectors is rotated across a radially tapered space between the guides. A magnetic record and/or playback head is positioned to urge at least a portion of a radial sector of the disk, deflected from the plane, towards the tapered space to effect a reverse deflection of the portion in the vicinity of the head. Thus the reverse-deflected portion is substantially conformed with the radially directed forces along the rotated disk, thereby assuring an intimate and stable head-to-disk relation.
