Filed: 1992-11-30
Abstract: PURPOSE:To suppress static noise detection at the time of reproducing and to prevent the electrostatic destruction of a yoke by forming this yoke of a soft magnetic film and eliminating a potential difference and charge accumulation between a magnetic core and a recording medium. CONSTITUTION:A pair of upper and lower magnetic layers 3, 4 are formed via a nonmagnetic insulating layer 2 on a conductive substrate 1. These layers as a magnetic shield are provided with a yoke 6, the front end of which exists in a front end gap part 4a between the upper layer 3 and the lower layer 4 and which faces the surface of a magnetic recording medium and gathers the magnetic fluxes from the magnetization recorded on the medium surface within the nonmagnetic insulating layer 5 between the layers 3 and 4. An MR element 7 having two pieces of leader electrodes 7a connected by superposing the rear ends of this yoke via the layer 5 and the layers 3, 4 to serve as magnetic poles are coupled in a magnetic path coupling part 4b. Spiral coil conductor layers 8 and an insulating protective layer 9 for the layer 3 are circumferentially provided. As a result, the combined magnetic head is constituted and is connected via a columnar conductive material 10 to the substrate 1. Further, the substrate 1 is grounded or is connected at the same potential as the potential of the medium to eliminate the charge accumulation between the magnetic core and the yoke.

Title: Measuring method of film thickness of semiconductor multilayer thin film
Inventor: SAKURADA TAKASHI
IPC: G01B11/06
Filed: 1988-12-22
Abstract: PURPOSE:To enable accurate measurement of the film thickness of each layer of a semiconductor multilayer thin film by making a monochromatic light of a prescribed long wavelength incident vertically while varying the wavelength continuously and by measuring the spectrum of a transmitted light. CONSTITUTION:A white light being used as a prober, the light incident vertically on a multilayer thin film is reflected in a multiple way by each layer and then emitted as a transmitted light from the back of a crystal. The intensity of this transmitted light is detected as a superposition of an oscillation spectrum corresponding to the film thickness of each layer as shown in a Figure (b) in a transmission area of a semiconductor constituting the thin film. By subjecting this spectrum to Fourier transform in an appropriate range of wavelength, the spectrum at a position proportional to the film thickness of each layer can be known exactly as shown in Figure (c). From the value of this spectrum, the film thicknesses of a plurality of thin films can be determined simultaneously.
