    • A disk (1) is constituted of a substrate (11), an aluminum signal layer (12) in which pits (14) are made, and a protective plate (13). An information reproducing device reproduces information from the disk (1) by means of a reproducing circuit (5) by convergently emitting an electron beam (E) from an electron gun (40) and detecting the variation of the intensity of the reflection of the beam (E) with a detector (42). A recording medium (20) is constituted of a conductive layer (22), an insulating layer (23), and an island-like fixed electrode (24) formed on the layer (23) and electrically insulated from its periphery. The fixed electrode (24) has a memory function. To write information on the medium (20), electrons are implanted into the electrode (24) with an electron gun (40). To erase all the information at a time, a voltage is applied across the conductive layer (22). To read out information, the electrostatic effect between the fixed electrode (24) and its counter electrode is utilized. Therefore, the information recording capacity of the medium (20) is increased and the information reading accuracy from the medium (20) is improved.
    • 盘(1)由衬底(11),其中制成凹坑(14)的铝信号层(12)和保护板(13)构成。 信息再现装置通过从电子枪(40)会聚地发射电子束(E)并通过再现电路(5)从盘(1)再现信息,并且检测光束的反射强度的变化 (E)与检测器(42)。 记录介质(20)由导电层(22),绝缘层(23)和形成在层(23)上并与其周边电绝缘的岛状固定电极(24)构成。 固定电极(24)具有记忆功能。 为了在介质(20)上写入信息,用电子枪(40)将电子注入到电极(24)中。 为了一次擦除所有信息,跨越导电层(22)施加电压。 为了读出信息,利用固定电极(24)与其对置电极之间的静电效应。 因此,介质(20)的信息记录容量增加,并且来自介质(20)的信息读取精度提高。
