ABSTRACT:
A mechanism for supporting a pair of magnetic core heads for reading and writing magnetic codes of a flexible disk having magnetic coatings thereon while the disk is rotating. Each of the heads is disposed on either side of the disk. The head supporting structure allows one of the heads to rock about a radial axis with respect to the disk, i.e., pitching, and to rock about a circumferential axis with respect to the disk, i.e., rolling, as well as to move in the direction normal to the disk face. On the other hand, the other head is allowed to pitch and move normally to the disk face but prevented from rolling. Thus, it is possible to minimize the radial dislocation of the head core with respect to the recording tracks, while effectively ensuring follow-up characteristics of the head.
