A control system for executing an application program is disclosed herein. A spectrum analyzing unit specifies a predetermined number of sets of the bands in decreasing order of the correlation between the spectrum distributions from among the bands obtained by equally dividing the above spectrum into equal bands, and then specifies one of the two specified bands as a removed band and the other as a interpolation band. A plurality of connectors is provided. A plurality of insulating portions are formed on the rear substrate, each of which is arranged between every two neighboring cathodes. As the incidence angle of an airflow colliding against a step defined at the leading end of the front air bearing surface gets decreased, the pitch angle of the slider body also gets decreased in the flying head slider during flight.
