An integrated x-ray and ultrasound medical imaging system is provided, wherein a radiation detection means and ultrasound transducer may be disposed for scanning movement for image acquisition along either the same or substantially coincidental paths. A perpendicular recording element includes a main magnetic pole film for emitting a perpendicular magnetic field and is supported by a slider. This strategy supports resource capacity schedules and request priorities as supported by prior art, but simultaneously supports the enforcement of allocation limits applied to a property expressed in the allocation request, namely the location of the work to be performed, or a location, resource pair to perform the work.
