    • A magnetic field H(x) or a reproducing beam L(x) of light whose intensity pattern is different is applied to the recording position of a magneto-optical recording medium, and different information corresponding to the patterns is read out of the same recording position. The function H(x) or L(x) is a password for obtaining the information. Only a person who knows the function can access the specific information recorded on the magneto-optical recording medium. The function H(x) or L(x) is a function such that the magnetic field intensity or the beam intensity is modulated with respect to the recording position (x) in such a manner that the information can be reproduced while magnetic domains are picked up from contiguous domains in the recording region at specific intervals. In addition to the security application, the information can be reproduced n times while a reproducing beam PL/PH, which is subjected to power modulation so as to apply a high power PH with a period n times the recording clock, is being projected to a specific magneto-optical recording medium such that magnetic domain expansion reproduction is possible, thereby improving the reproducing C/N significantly.
    • 将强度图案不同的光的磁场H(x)或再现光束L(x)施加到磁光记录介质的记录位置,并且从同一记录中读出与图案对应的不同信息 位置。 函数H(x)或L(x)是用于获取信息的密码。 只有知道该功能的人才可以访问记录在磁光记录介质上的特定信息。 函数H(x)或L(x)是这样的功能,使得磁场强度或光束强度相对于记录位置(x)被调制,使得可以在拾取磁畴时再现信息 从特定间隔的记录区域中的连续域开始。 除了安全应用之外,可以再次n次地再现信息,而将经过功率调制以便施加具有n倍于记录时钟的周期的高功率PH的再现光束PL / PH投影到 特定的磁光记录介质,使得磁畴扩展再现成为可能,从而显着提高再现C / N。

    • PURPOSE: To increase interest by enabling a player to play various kinds of games while using characters desired by a player and to improve the commercial value of this kind of cassette for game by combining a scenario cassette with a character cassette irrespective of contents recorded on them, respectively. CONSTITUTION: When the scenario cassette 10 and the character cassette 20 are inserted to the slots 31, 32 of a game machine main body 30, for example, the person recorded on the character cassette 20 can be set as the character in a scene in which the character is set when the game is started. Therefore, the player can set the character with whom the player has a feeling of intimacy. The image of a selected specific person is outputted from an output terminal to the scenario cassette 10, and it is inserted to the scene outputted from a scenario part in the image composite circuit of the scenario cassette 10, then, outputted to the display screen of a television set, etc.

    • PURPOSE: To unnecessitate the knowledge of each communication network and to simplify operations by installing a terminal support equipment and a control server on an arbitrary communication line and using them by connecting them with a subscriber terminal. CONSTITUTION: When the terminal support equipment 20 of a communication terminal support network system 1 starts the use of the subscriber terminal 40 of the communication network existing on arbitrary communication lines 10 to 13 including a connected public line 10, the equipment 20 displays the information on arbitrary communication equipments 50 A to 50 F which are possible to communicate with the terminal 40 on the monitor of the terminal 40. The menu data and use data to be held in a rewritable memory device is displayed. A control server 30 recognizes the use information of the equipment 20 by a use data sum-up means and rewrites the menu data holding means of the equipment 20 by a maintenance means. By this constitution, the knowledge of the subscription procedure to each of the lines 10 to 13 and the communication network, etc., and the operation means, etc., becomes unnecessary in the terminal 40.
