Abstract
Two magnetic heads are mounted respectively in front of two springs, and face each other across a gap in a frame into which a recording disk can be exerted. The springs are respectively flexed back by means of two spring biased pivot levers, so that the heads do not engage the disk. These levers have tongues in their front, which hold the springs down. A cone-ball actuator pivots the lever towards each other permitting, in turn, the springs to flex towards each other so that the heads engage the disk.
