Title: Data writing circuit
Inventor: USUKI HIDEO
IPC: G11B5/09
Filed: 1985-08-07
Abstract: PURPOSE:To prevent the magnetization caused by a write current, and to prevent the characteristic of a head from being deteriorated, by inverting a write current by conducting and cutting off an electric conduction path to a magnetic head by a write gate signal, and also switching the magnitude of the write current. CONSTITUTION:When a write gate signal WG becomes on, a transistor TR 1 becomes 'on' through a delaying circuit DL, and a state that a write current can be supplied to a magnetic head HD is formed. In this state, when a write data WD is sent, an FF is inverted by a timing of its fall, TR2-TR5 are brought to switching, the write current is inverted and a data is recorded onto a magnetic medium. Next, when the signal WG becomes off, the FF is inverted, and the write current is inverted. In this case, a switch S becomes off, and a write current Iw' flows through only a resistance R8. Since the current Iw' of the reverse direction to a write current Iw flows, the residual magnetization of the head HD is suppressed small.

Abstract: PROBLEM TO BE SOLVED: To detect a mark position with high accuracy by adjusting an incident angle of light incident on an object so that intensity of reflected light from a mark in an image pickup means is made maximum, so that the SN ratio of a signal of scattered light in a mark is made optimum. SOLUTION: An image processing part 10 takes in a picture signal which is outputted from a CCD camera 7. An alignment mark 2 is detected from a signal level of the picture signal, to find a positional coordinate thereof. Further, the image processing part 10 takes in a picture signal, which is outputted from the CCD camera 7, when the incident angle θ of oblique illumination of the alignment mark 2 by each oblique illumination means 15a and 15b is changed. Based on a signal level of the picture signal, a place where the intensity of scattered light from the alignment mark 2 indicates a maximum value is detected. The SN ratio of the scattered light and the signal in the mark 2 is optimized, so that unevenness of a thin film and resist on the surface of a semiconductor wafer 1 and irregularity of the resist have hardly influence.  Thereby the alignment mark is detected with high accuracy.
