摘要： A collector lead-out portion and a base lead-out portion are formed so as to oppose to each other in such a manner that active regions including a collector, a base and an emitter are sandwiched therebetween. The collector lead-out portion and the base lead-out portion are formed by ion implantation or selective epitaxial growth. Thus, a planar type heterojunction bipolar transistor capable of a high density of integration is formed.

摘要： An optical recording medium, an optical recording and reproducing method, and an apparatus that can record and reproduce multilevel information at a high density and with a high S/N ratio. Recording light emitted from a light source is collimated by a collimation lens and introduced into a polarization rotary device. Recording light transmitted by the polarization rotary device is focused by an objective lens onto an optical recording medium. In response, a photo-induced birefringence is recorded on the optical recording medium. Multilevel recording is performed by controlling a voltage applied to the polarization rotary device to change a polarization angle θ of recording light. Reproduction is performed by detecting light reflected from the optical recording medium with an analyzer and a detector.

摘要： The present invention provides a recording/reproducing head, a recording/reproducing disk, and a recording/reproducing disk apparatus that are capable of high density recording, cost reduction, easy tracking control, and high speed seek operation. A collimated beam that is incident onto an incident surface of a transparent condensing medium is reflected on a reflecting film formed on the surface of a reflecting surface to condense on a second surface, and a beam spot is formed near the end of the second surface. The beam condensed on the beam spot leaks as a near field wave and is propagated to a magneto-optic recording film of a recording/reproducing disk, and information is OAM-recorded cooperatively with the magnetic field of a coil. In reproduction of the information, a leakage magnetic flux that comes from the recording film is detected by a magnetic sensor.
