A magnetic sensor, formed from a pair of magnetically free layers located on opposing sides of a non-magnetic layer, and method for its manufacture, are described. The arms each have a first end formed on the inner section and a second, free end which is bent away axially with respect to a central axis of the plate spring. The hub is used to seat a disk thereon. This will allow information of be stored by the LIGHT TRIGGERED BENDING ELEMENT LIGHT SWITCH that are made to latch.
