A carrier for use in a two component developer for developing an electrostatic latent image is provided. The present invention is characterized in the preparation of carbon nanotube-containing fiber materials with higher conductivity and the improvement of the spinning property of the conductive masterbatches to avoid blocking and yarn breakage during the spinning process. The system further includes a refracting surface disposed to intercept energy from the plurality of apertures and a partially reflecting surface to direct portions of the intercepted energy back toward the plurality of apertures with the directed energy being distributed about the plurality of apertures. The method further includes allocating a first data block to the first target physical location writing the first data block to the first target physical locations, wherein the first data block comprises a first portion of the first data item.
