In this study, we prepared sputtering cathode for large sputtering thin film in the facing targets sputtering(FTS) system. Before fabrication of cathode equipment, we investigated optimal magnetic flux in the sputtering cathode by using magnetic field stimulation(Comsol). According to the result of magnetic field stimulation, we manufactured the cathode. After we mounted laboratory-designed cathode on FTS system, the discharge properties were observed in vacuum condition. In addition, ITO films were deposited on glass substrate and their electrical and optical properties were investigated by various measurements (four-point probe, UV-VIS spectrometer, field emission scanning electron microscopy(FE-SEM), Hall-effect measurement).

In conducting systems based on LB films, TCNQ derivatives have been extensively studied as electron acceptor molecules. We have investigated the optical, electrical, and magnetic properties of Viologen-(TCNQ￣)$_2$LB films. In UV/visible absorption measurements, we have observed TCNQ￣ peak at 380 nm and dimer peak at 620 nm. The electron spin resonance measurements infer that Viologen-(TCNQ￣)$_2$LB film exhibits anisotropic properly. In other words, the LB film shows angular dependence. Iodine doping affects the degree of charge transfer and the conductivity of the films. The UV/visible absorption spectra of the LB film doped with I$_2$show peaks at near 400~430 nm and there is no dimer absorption peak. The in-plane electrical conductivity of the undoped film is approximately 4.2$\times$10$^{-6}$ S/cm.

An electroless plating both for normal orientation of HCP-structure of Co-P to the film plane was developed. An ammonical succinate-citrate bath containg MnSo4, NiSO4 was studied Ni was codeposited into the films in order to decrease the saturation magentization (MS) since low Ms is necessary to decrease the magentizing fild. Mn was also codeposited to increase perpendicular orentaon of Co-P film. Effects on film composition and magnetic properties were studid in connection with follwing four factors such as concentration of NiSo4 and MnSo4, bath temp and pH.

This paper describes a theoretical model for the prediction of the spacing profile between a flexible magnetic tape tensioned around a rotating drum and a protruding head mounted on the drum. The analysis is based on the coupled equations controlling the elastic deformation of the tape and the hydrodynamic pressure of the gas film. Some results are presented for a cylindrical head.
