ABSTRACT:
A magnetic head-to-media backer device comprising an elastically deformable reed-like backer member adapted to urge a flexible magnetic media into contact with a magnetic head, is characterized in that a rigid frame has a cavity defined at least by a pair of opposite walls shaped to hold the backer member bent in an arc with two opposite leg portions of the backer member captured within the cavity to permit them to be deformed against respective ones of the opposite walls and a center portion of the backer member protruding from an opening to the cavity to permit it to be depressed at least part way into the opening to deform the leg portions toward the opposite walls. Thus, when a magnetic head is forced against the center portion the center portion can be depressed into the opening until the leg portions are deformed against the opposite walls, thereby providing a very stable support for the magnetic head.
