A thin-film magnetic head and a method of manufacturing the same of the invention achieve precise control of a magnetic pole width with and a sufficient overwrite property even when the pole width is reduced and achieve precise control of a throat height. The invention further relates to a compressed air supply facility having such a compressor arrangement, to a vehicle having a pneumatic system, particularly an air spring system and such a compressed air supply facility, and to a method for operating a compressed air supply facility on a vehicle having such a compressor arrangement,. According to the method, a first select signal from each pair of select signals is asserted to decouple the input and output terminals for each cell. The support brackets transfer loads from the rack member to the vehicle without requiring mounting to bumpers or a windshield frame of the jeep type vehicle. The base is centered about the longitudinal axis.
