Abstract: PURPOSE: To reduce the fall time of an IGBT included in an IC by ordinary IC technology without irradiation with an electron beam by extracting a second conductivity type semiconductor layer including a collector region formed of a first conductivity type semiconductor layer as an electrode. CONSTITUTION: A heavily doped control collector layer 4 is provided on an N-type substrate 1, and brought into ohmic contact with an output electrode 4b.

Abstract: PURPOSE:To apply the magnetic field of a required magnitude to a disk surface at all times by detecting the spacing distance of a magnetic field applying means to a disk surface and controlling the position of the magnetic field applying means in such a manner that the specified spacing distance is attained in accordance with the detected output. CONSTITUTION:The distance between the objective lens of an optical head 4 and the disk surface fluctuates according to the rotation of the disk 1 if the disk 1 has a warp. The focus error signal of the polarity and level corresponding to the fluctuation direction and fluctuation component is thereby outputted from an error detecting circuit 12. The spacing distance of a magnetic head 5 to the disk surface eventually fluctuates by as much as the same distance in the opposite direction as the distance between the optical head 4 and the optical disk surface fluctuates according to the rotation of the disk 1. The polarity and level of the focus error signal indicate the fluctuation direction and fluctuation component as the driving signal of the magnetic head 5 as well and this error signal can be used as the driving signal for the magnetic head 5. The spacing distance of the magnetic head 5 to the disk surface is maintained always constant by vertically moving the magnetic head 5 by the effect of an electromagnet 10 and a stationary magnet 11 in accordance with the error signal.
