IPC: H04N9/64
Filed: 1980-07-30
Abstract: PURPOSE:To receive TV signals, differing in system, with simple circuit constitution, by switching input band characteristics of a sound IF signal automatically by a detection signal obtained by detecting the output amplitude variations of a vertical oscillating circuit due to a difference in field frequency. CONSTITUTION:The output of a vertical synchronism discriminating circuit, which inputs the 1st and 2nd vertical synchronizing signals of the B/PAL and M/NTSC systems and outputs the 1st and 2nd voltage levels synchronizing with those synchronizing signals, is applied to the terminal E of a circuit switching sound IF band characteristics. This switching circuit is provided with a sound IF detector 5, capacitors 7-10, a diode 11, an IF transformer 12, etc. For B/PAL reception, a voltage inputted to the terminal E is held at 0 to turn off the diode 11, and the band characteristics of an IF input resonant circuit are set to the reception frequency of the B/PAL system. For M/NTSC system reception, on the other hand, the voltage inputted to terminal E is held at a prescribed level to turn on the diode 11, and then the capacitor 8 is short-circuited to set the band characteristics to the frequency of the M/NTSC system.

IPC: G11B5/127
Filed: 1983-06-13
Abstract: PURPOSE:To increase the magnetic resistance to prevent saturation of a recording medium of high permeability which is due to the magnetic flux generated from a substrate and to improve the recording efficiency, by using a nonmagnetic insulated material to form the area near the end face of the substrate corresponding to the recording medium. CONSTITUTION:A nonmagnetic insulated material 10 is used to form the area close to the face opposite to a recording medium 6 for a substrate 11 made of a ferromagnetic material 9, and a spiral coil layer 3 is formed on the material 10. Then a main magnetic pole layer 14 consisting of a ferromagnetic thin film is provided on the layer 3. The magnetic flux generated by a signal current flowing to the layer 3 passes a magnetic path of the layer 14  a vertical anisotropic medium 4  a medium 8 of high permeability   the material 10   the material 9  the layer 14. Thus the medium 4 set under a ''Permalloy'' film 12 of the layer 14 is intensively magnetized. Thus the saturation is eliminated for the medium 8 of the medium 6 due to the magnetic flux generated from the substrate 11. At the same time, the saturation of the layer 14 is also suppressed. This ensures the intensive magnetization up to the tip of the main magnetic pole and improves the recording quality.
