摘要： This invention is directed to an improvement in a novel magneto-optical disc reproducing method of the record information erasing type or the record information raised or transfer type wherein a technique is employed to prevent the dimension of an actual reproduction region from varying by a change of temperature or linear velocity of a magneto-optical disc. To realize this, reference information is recorded on a magneto-optical disc to reproduce this reference information prior to actual data reproduction to detect the regenerative RF signal level to control a laser power or an external magnetic field so that the regenerative RF signal level becomes equal to a level optimum for reproduction, thus allowing the dimension of an actual reproduction region to be an optimum fixed dimension at all times. At the time of actual reproduction, control is made so that the controlled laser power or external magnetic field is maintained.

摘要： The width of a charge storage electrode and a control electrode in the column direction is set to be wider above an element isolation region than that above a channel region. Therefore, the capacitance between the control electrode and the charge storage electrode can be increased to improve the coupling ratio in a nonvolatile semiconductor memory device. Also, a first interconnection layer is equal in height above the control electrode and above the channel region, so that patterning of the first interconnection layer can be carried out easily and precisely.

摘要： A method for reproducing a magneto-optical recording medium the recording pits of which are erased or relieved with rise in temperature of the recording medium caused by radiation of a readout beam, or an optical recording medium the reflectance of which is changed with rise in temperature of the recording medium caused by radiation of the readout beam, in which, when the line recording density of the recording medium is changed, the size of the effective reproducing region is controlled to an optimum value conforming to the line recording density to assure a stable reproducing state. To this end, with the magneto-optical disc 11 for example, being rotated at a constant angular velocity, a detecting unit 17 is provided for detecting the radial position of the magneto-optical disc 11 and the laser power as well as the external magnetic field is controlled depending on an output of the detecting unit 17 for controlling the size of an effective reproducing region to an optimum value conforming to the line recording density at each reproducing position.

摘要： A method and apparatus for recording and reproducing information onto and from a magneto-optic recording medium is disclosed. The magneto-optic recording medium has at least a reproducing layer and a recording layer. A recording optical head records information on the magneto-optic recording medium. A reproducing optical head has a reading light beam for reading information recorded in a region within a spot of the reading light beam by magneto-optic effect by changing a state of magnetization of the reproducing layer and at the same time irradiating the recording medium with the light beam. A wavelength of the recording light beam emitted by the recording optical head is substantially smaller than a wavelength of the reading light beam emitted by the reading optical head. A minimum ratio of the wavelength of the recording light beam to that of the reproducing light beam is 1:3.

In this case, the reflection of the side beam of the reflected beams on the optical recording medium which passes through the objective lens, the beam splitter and the diffraction grating and returns to the semiconductor laser apparatus is redirected at a laser beam emission header portion to thereby reduce the influence by the skew of the optical disc on the tracking error signal.
