摘要： The second harmonic wave of a solid laser light which is emitted from a second harmonic wave light source is divided into a plurality of laser beams by a diffraction grating. The divided laser beams are converged on a record carrier into a plurality of light spots by an optical head. Magnetic field generating coils for applying magnetic fields to the respective light spots in accordance with the recording signals from a signal line are disposed under the record carrier. Part of the solid laser light is reflected and input to a beam splitter. Since part of the light input to the beam splitter is taken out, a stabilizer controls the output of the solid laser light from the second harmonic wave light source, parallel recording/reproduction using the plurality of light spots which are arranged on the record carrier is enabled and the formation of the plurality of light spots is effectively controlled. Thus, a magneto-optical recording and reproducing apparatus which is capable of high-density recording and high-speed data transfer, which supplies a stable and accurate optical output, and which facilitates the control of the optical output is provided.

A bobbin (5) having an insulating property covers the partial cores (4a) and (4b) and magnets (2) and (3) in the winding direction of the horizontal correction coils (L1) and (L2), and a vertical correction coil (L3) is wound on the bobbin (5) around the partial cores (4a) and (4b) along the windings of the horizontal correction coils (L1) and (L2). That is to say, the vertical correction coil (L3) is wound over the horizontal correction coils (L1) and (L2) along the periphery of their windings with the bobbin (5) interposed therebetween. This vertical correction coil (L3) is wound in such a direction that it produces a magnetic field directed to cancel the bias magnetic field produced by the magnets (2) and (3).

摘要： An image distortion correction circuit is provided in which a horizontal deflection current (IH) flows through horizontal correction coils (L1, L2) and a vertical deflection current (IV) flows through either of vertical correction coils (L3, L4). The vertical correction coils (L3, L4) and the horizontal correction coils (L1, L2) are wound on the same core (4). A pair of magnets (2, 3) on opposite ends of the core (4) apply a biased magnetic field from the north pole toward the south pole. The anode of a diode (D1), the cathode of a diode (D2) and a first end of a resistor (R1) are connected to an intermediate terminal (P11) through which the vertical deflection current (IV) flows. A first end of the vertical correction coil (L3) is connected to the cathode of the diode (D1). A second end of the resistor (R1) and a terminal (P4) are connected to a second end of the vertical correction coil (L3). A first end of the vertical correction coil (L4) is connected to the terminal (P4), and a second end of the vertical correction coil (L4) is connected to the anode of the diode (D2). The image distortion correction circuit minimizes the degradation of vertical deflection sensitivity to perform an intermediate pin distortion correction.

摘要： A laser beam machine comprises an optical fiber cable for transmitting laser light, a beam output optical assembly for converging and emitting a laser beam and flexible protective conduits arranged along the X- and Y-axes accommodating the optical fiber cable as well as power and control cables for X-and Z-axis drive motors and an assist gas tube. While the beam output optical assembly can be moved along the X-, Y- and Z-axes, the flexible protective conduits do not bend in excess of the permissible bending radius of the optical fiber cable. The laser beam machine thus constructed provides improved reliability, safety and maintainability of the optical fiber cable as well as high laser beam converging performance and an enlarged machining area. In another embodiment a nozzle centering device is provided between an optical fiber cable and a nozzle housing holding a collimator lens and a condensor lens to align the optical axis of the optical fiber cable with the nozzle housing.
