Title: Magnetic recording and reproducing method
Inventor: TOMITA MASAO
IPC: G11B5/008
Filed: 1983-12-06
Abstract: PURPOSE:To improve the recording density and also to erase and record again the information recorded to shallow layer part on a magnetic medium, by recording the 1st information on the medium in the prescribed track width and then the 2nd information at the shallow layer part on the same track and in the smaller track width than the 1st information. CONSTITUTION:The recording/reproducing of analog signals needs less S/N than the digital signals. In this connection, the digital signals (the 2nd information) of a wide band are recorded at a shallow layer part of a record area 8 where the video signals (the 1st information) are recorded in the smaller track width than the video signal track. Thus a digital signal record area 7 is secured. The digital signals are recorded just in a limited area of the shallow layer part. Therefore the lower layer part of the area 7 also can contribute to the output of the video signal. Thus it is possible to record the digital signals having a practical code error factor on the analog signals with no S/N deterioration of those analog signals recorded previously.

Title: End point detecting method in etching of semiconductor device
Inventor: NAGATA HIDEO
IPC: H01L21/302
Filed: 1991-09-10
Abstract: PURPOSE:To accurately detect the end point of etching by forming, under a film to be etched, a film which generates the light having the wavelength remarkably different from that of the film to be etched and then detecting the timing when the light having such wavelength is generated. CONSTITUTION:A fluorocarbon film 6 is formed on a substrate 5 including the stepped area. Thereafter, a resist 7 and a mask 8 of O2 RIE are formed on the fluorocarbon film 6. This fluorocarbon film 6 includes fluorine F having the peak of light emission in the wavelength of about 700nm which is remarkably different from 480nm which is the peak of light emission of an ordinary resist 7. A substrate 5 is set within an apparatus to conduct the etching and when the fluorocarbon film 6 is exposed, a light emitting intensity at 704nm of the fluorine F generated from the film 6 rises rapidly. Therefore this rise timing is measured. Therefore, even if a stepped area exists and an etching rate is ununiform, the end point of etching can be detected easily and accurately.

Current regulators 15a-15d employing the separated DC amounts as current command values and the positive and negative phase biaxial components from an inverter 5 as current detection values are provided and the inverter 5 is operated based on the regulating operations of the current regulators 15a-15d thus compensating for the negative phase component as well as the positive phase component of load current. This constitution substantially nullifies fluctuation in the system voltage.
