    • A composite magnetic antenna for information communication utilizes a magnetic field component as well as a composite RF tag using the composite magnetic antenna, which can be embedded in metals while maintaining a sufficient communication sensitivity unlike conventional RF tags which are unusable in the metal embedding applications. The composite RF tag for transmitting and receiving information using an electromagnetic induction method includes a magnetic antenna on which an IC is mounted, and an insulating material and a metal material or a conductive material which are formed around the magnetic antenna. The magnetic antenna includes a central core formed of a magnetic material, and an electrode material formed into a coil around the central core. The insulating material is formed around the magnetic antenna except for one longitudinal end of the coil of the magnetic antenna. The metal material or the conductive material is formed on an outside of the insulating material.
    • 用于信息通信的复合磁性天线使用复合磁性天线,使用复合磁性天线,其可嵌入金属中,同时保持与在金属嵌入应用中不可用的常规RF标签相当的通信灵敏度。 使用电磁感应方法发送和接收信息的复合RF标签包括安装有IC的磁性天线以及围绕磁性天线形成的绝缘材料和金属材料或导电材料。 磁性天线包括由磁性材料形成的中心芯和围绕中心芯形成为线圈的电极材料。 绝缘材料围绕磁性天线形成,除了磁性天线的线圈的一个纵向端。 金属材料或导电材料形成在绝缘材料的外侧。

    • An information recording apparatus includes an information obtaining unit, a sign arrangement generating unit, a sign arrangement recording unit. The information obtaining unit obtains information to be recorded on a recording medium. The sign arrangement generating unit, based on information to be obtained by the information obtaining unit, generates an arrangement having three or more kinds of signs for expressing the obtained information. The sign arrangement recording unit, while shifting recording positions of a recording area included in the recording medium, records physical features sequentially into the respective recording positions of the recording area included in the recording medium. And each physical feature corresponds to one kind of the signs.
    • 信息记录装置包括信息获取单元,符号排列生成单元,符号排列记录单元。 信息获取单元获得要记录在记录介质上的信息。 符号排列生成单元基于由信息获取单元获得的信息,生成具有用于表示获得的信息的三种或更多种类型的符号的布置。 符号排列记录单元在将包括在记录介质中的记录区域的记录位置移位的同时,将物理特征顺序地记录到包括在记录介质中的记录区域的各个记录位置。 每个物理特征对应于一种迹象。
