Abstract: PROBLEM TO BE SOLVED: To surely prevent a substrate from being negatively charged by mounting a ferromagnetic substance which has a hole in a position corresponding to a hole in a reflector electrode and which has the same potential as the reflector electrode, in such a way that it surrounds the outer periphery of the reflector electrode. SOLUTION: Electrons in a plasma 32 introduced through a hole 25 in a reflector 24, and other electrons such as thermoelectrons, are guided by magnetic flux 76 to move toward a ferromagnetic substance 80 or the reflector electrode 24. In that case, the electrons having an energy smaller than the potential of the electrode 24 and of the ferromagnetic substance 80 are bounced back by the potential, forced into the electrode 24, and pulled into an ion beam 2 by its potential. The electrons having an energy greater than the potential of the electrode 24 and the ferromagnetic substance 80, however, overcome the potential, impinge on the inside of the electrode 24 or the ferromagnetic substance 80, and are collected by them. Therefore, only the low-energy electrons not collected by the electrode 24 are present near the entrance of the electrode 24, working to neutralize a positive charge caused by the application of the ion beam to the surface of a substrate.

Abstract: PURPOSE:To improve the amplitude margin and to improve the recording density by generating such a signal as a read edge signal exclusive of its DC variant and generating a gate signal from said signal and a threshold level with a gate signal generating circuit. CONSTITUTION:1st and 2nd detection circuits 22 and 23 detect positive and negative envelopes of an output edge signal from a subtraction circuit 21. A mean value detecting circuit 24 detects the DC variant of the output edge signal of the subtraction circuit 21 in the amplitude direction according to both detecting levels of the 1st and 2nd detection circuits 22 and 23, and the DC variant is fed back in negative as the form of a correction signal to the subtraction circuit 21.

By this output edge signal and the threshold level, the gate signal generating circuit 36 outputs the gate signal. By this method, a lack of the gate signal and a fluctuation in pulse width can be prevented, thus improving the amplitude margin.
