Can a device be constructed of a super conducting disk connected to a electromagnet that generates a field such that the disc locks "in" the field generated by the electromagnet such that the device self levitates without the need for track or permanent magnets?

No, the locking occurs relative to the field which is now moving with the device. It's like trying to push your dashboard to move your car.
