The present invention provides a technique for achieving reliable delivery of bulk data from a single origin to multiple destinations such that the origin only sends the data once to the network, without waiting for the destinations to be connected to the network. First and second developer carrying members carry the developer from inside of the developing container toward an image bearing member by rotations thereof in the same rotational directions. The UE provides a call to the particular UE, via a LTE network and an Internet protocol Multimedia Subsystem network, when the particular UE is a VoLTE capable device. The method is applied to the production of the write structure of a magnetic readwrite head, where a portion of the pole structure and the inductive coils are fabricated in the same plane with a close spacing and both having a vertical aspect ratio of more than about 2:1.
