    • The optical recording medium comprises a light-transmitting substrate 11 having a spiral groove 11a formed thereon and a recording layer 21 containing an organic dye wherein the average inclination angle θa of the wall of the groove 11a on the inward side thereof is greater than the average inclination angle θb of the wall of the groove on the outward side thereof. In this arrangement, when the recording layer 21 is formed by a spin coating method, the dispersion of the thickness of the recording layer 21 inside the groove 11a can be prevented, making it assured that the recording layer 21 can be provided with a desired thickness over an area inside the groove 11a ranging from the inward side thereof to the outward side thereof. As a result, heat of laser beam emitted during recording can be almost uniformly dissipated over the area inside the groove ranging from the inward side to the outward side thereof to eliminate the effect of thermal interference between marks, making it possible to secure a wide power margin during a high speed recording.
    • 光记录介质包括其上形成有螺旋槽11a的透光基板11和包含有机染料的记录层21,其中槽11a的内侧的壁的平均倾斜角θa大于平均值 在其外侧的槽的壁的倾斜角度。 在这种布置中,当通过旋涂方法形成记录层21时,可以防止记录层21在凹槽11a内的厚度的分散,使得可以确保记录层21可以具有期望的厚度 在槽11a的内侧和外侧之间的区域内。 结果,在记录期间发射的激光束的热量可以几乎均匀地散发在从内侧到外侧的槽内的区域内,以消除标记之间的热干扰的影响,使得可以确保宽的功率 高速录制时的余量。

    • A learning-support device offers a sufficient learning effect even in a field of learning that sets its goal on mastering a motion itself. A question-screen display part displays a question-screen composed of a question and moving images as choices for an answer. A selection reception part receives a user-selection indicating which of the moving images on the question-screen is selected by a user. A correct/incorrect determination part determines whether the user-selection is correct or incorrect. When the user-selection is determined as correct, a correct-answer-explanation-screen display part displays a correct-answer-explanation-screen including an explanation for the correct answer and the correct moving image. When the user-selection is determined as incorrect, an incorrect-answer-explanation-screen display part displays an incorrect-answer-explanation-screen including an explanation for the incorrect answer and the correct moving image.
