Abstract
Disclosed is a movable magnetic head block assembly for a double sided flexible magnetic disk storage device, wherein a pair of mutually opposed disk contacting surfaces, at least one of which comprises an electromagnetic transducer head, are in contact under pressure with the opposite sides of a magnetic disk so that information can be recorded or retrieved from the disk. To enable the unimpeded exchange of disks, an arrangement is provided whereby at least one of the disk contacting surfaces is mounted on an individual flexibly mounted retractable support arm which is normally urged under pressure against a stop, in the direction of the disk to place the disk contacting surfaces in position for normal operation, but which can be retracted against that pressure, thus withdrawing the disk contacting surface away from the surface of the disk, so that the disk may be exchanged without impediment. At least one of these flexibly mounted support arms is included in a position adjustable support arm assembly, comprising an arm which the head is mounted, an anchor member and a flexible means connecting the two, the adjustment of the position of the anchor member enabling the positioning of the disk contacting surface with respect to the rotational center of the disk to be effected, by a suitable known method, with accuracy, simply and reliably, without the requirement of any extraordinary skill.
