Claims Analysis

Total Claims: 2
Claim 1
Independent Claim 225 words
In a storing device for signals including at least one rotating magnetic storage disk having at least one signal storing surface including storage tracks for storing data, access means with individually suspended transducer means for reading or writing data in said storage tracks, wherein the access means comprise a baseplate; an actuator rod; two first flexure means spaced apart and mounted on said baseplate, and supporting said actuator rod therebetween at two spaced locations for movement of said actuator rod along its longitudinal axis; each of said first flexures including two mounting means for attaching each of said flexures to said baseplate, means for receiving said actuator rod, and opposed elastic connecting portions, spaced symmetrically to said means for receiving, and interconnecting said means for receiving with said mounting means; a plurality of transducer means; a plurality of second flexure means, connected to said actuator rod, each including means for receiving one of said transducer means; transducer lifting means including a loading bar and a spaced pair of thermoelectrically energized suspension means which are selectively energizable so that the loading bar and the associated transducer means are positioned for flying in operative proximity to said signal storage surface when said lifting means are energized and said transducer means assume an inoperative position spaced from said signal storage surface when said transducer lifting means are deenergized.
