摘要： A magneto-optical disk is provided with a transparent substrate of a disk shape, and a multiple layered structure which is formed on the substrate and includes a plurality of transparent dielectric films and magnetic recording films which are alternatively layered. One method of reproducing the magneto-optical disk is enabled, which has the steps of inputting a circularly or elliptically polarized light on the magneto-optical disk, and detecting an intensity change of the light caused by the magneto-optical disk due to the circular dichroism effect thereof, as a reproduced signal. Another method of reproducing the magneto-optical disk is also enabled, which has the steps of inputting a linearly polarized light on the magneto-optical disk, and detecting a rotation change of a polarization plane of the light caused by the magneto-optical disk due to the magnetic Kerr effect, as a reproduced signal.

摘要： An optical recording element according to the present invention comprising: (i) a transparent substrate through which light passes; (ii) a transparent low-resistance layer having a specific resistance so as to prevent the adhesion of dust to the surface of the element caused by a static charge, the layer being formed on the surface, on which a light beam is incident, of the transparent substrate; and (iii) an optical thin film composed of at least one layer, formed on the other surface of the transparent substrate so as to transmit light beams used for recording, erasing and playback, and reflect lights which have wavelengths different from the wavelength of the above light beams and are within a specified visible region of the spectrum. With this arrangement, lights within a specified visible region of the spectrum are reflected so that the element appears to be colored according to the wavelengths of the reflected lights. Also, a problem often found in a conventional optical recording element having a transparent substrate of a resin material that the surface of the element is hardened by a light beam, can be solved. Even if a static charge is generated on the surface of such an element, the conductive transparent low-resistance substrate can eliminate the static charge outward whereby a static charge is less likely to be accumulated and the surface can be kept clean in order to improve the reliability.

摘要： A magneto-optical recording/reproducing device which records information by irradiating a light beam of constant intensity on a magneto-optical recording medium while simultaneously applying a magnetic field thereon through a recording magnetic head; and which reproduces the recorded information through a reproducing magnetic head. The magneto-optical recording medium has a magnetic film formed on a translucent substrate and the magnetic field applied through the recording magnetic head reverses in response to the information to be recorded. The recording magnetic head and the reproducing magnetic head are integrally provided on a single magnetic core in order to set their positions easily with respect to each other. By making a magnetic core end-face of the reproducing magnetic head smaller than a light beam spot, information recorded on areas smaller than the light beam spot can be reproduced. A large reproduced output may be achieved by using a magneto-optical recording medium which has a soft magnetic material layer made of soft magnetic material provided between the substrate and the magnetic film.

摘要： It is an object of the present invention to make it possible to easily wind a stator winding, enhance an occupied ratio in a stator core, reduce a winding resistance because there is no coil end, and change a field magnetic flux in accordance with a use.Stator pawl magnetic poles of a stator core extend from both sides in an axial direction alternately at locations opposed to a rotor to form a plurality of magnetic poles. With this stator core, it is only necessary to annularly wind a stator winding. Therefore, it is possible to enhance operability and an occupied ratio, and since there is no coil end, it is possible to reduce winding resistance. Since the rotor is a Randall type rotor having a field winding and a rotor pawl magnetic pole, it is possible to change the field magnetic flux in accordance with a use.

摘要： Stator claw poles are disposed at a stator core at a position facing opposite a rotor so as to alternately range from the two sides along the axial direction. With a plurality of magnetic poles thus formed, the distance by which the gap between the front end portions of the stator claw poles and the stator outer circumference ranges is increased, which, in turn, reduces the reactance guided to a stator coil. It is ensured that the magnetic reluctance manifesting between the front end portions of the stator claw poles and an enclosing member that holds the stator core, facing opposite the centers of the claw poles along the circumferential direction, is greater than the magnetic reluctance manifesting between the front portions and the stator core enclosing member facing opposite the front end portions.
