    • PURPOSE: A method for making an information recording medium for a probe type is provided to prevent the oxidation and the abrasion of a recording/playback process by forming a protecting film on a phase transition recording medium, and increase a recording/playback speed and prevent the abrasion by flattening the recording medium. CONSTITUTION: An electrode(101), the phase transition recording medium, and a conductive protecting film are sequentially deposited on a silicon wafer(100). A photo-resist film is formed on the conductive protecting film and a photo-resist pattern is patterned by a photo-lithography process. A conductive protecting film pattern(103a) and the phase transition recording medium pattern(102a) are formed by etching the conductive protecting film and the phase transition recording medium, and the photo-resist pattern is removed. The phase transition recording medium pattern is electrically insulated and an insulation film preventing the oxidation of the phase transition recording medium is deposited. The flattened insulation film(105a) is obtained by polishing/flattening the insulation file.
    • 目的:提供一种用于制作用于探针类型的信息记录介质的方法,以通过在相变记录介质上形成保护膜来防止记录/重放过程的氧化和磨损,并且提高记录/重放速度并防止 通过使记录介质变平的磨损。 构成:在硅晶片(100)上依次沉积电极(101),相变记录介质和导电保护膜。 在导电保护膜上形成光致抗蚀剂膜,通过光刻工艺对光致抗蚀剂图案进行图案化。 通过蚀刻导电保护膜和相变记录介质形成导电保护膜图案(103a)和相变记录介质图案(102a),并除去光刻胶图案。 相变记录介质图案是电绝缘的,并且沉积防止相变记录介质的氧化的绝缘膜。 平坦化的绝缘膜(105a)通过抛光/压平绝缘锉来获得。

    • PURPOSE: A data storage device is provided to make the size of a bit smaller as increasing a data reading speed, and to obtain a bigger signal to noise ratio, thereby solving a retention problem and problems of the data reading speed and an S/N ratio. CONSTITUTION: A data writing process is as follows. A conductor layer(34) is formed on top of a silicone substrate(35). An insulation layer(33) is formed on the conductor layer. When a current is applied to a metal electrode of a cantilever(32), a silicone tip(31) emits heat. If a demanded part of a polymer is heated by the heat, the polymer melts. A hole(38) pierced through the surface of the conductor layer is formed on a position where the polymer melts. The hole is used as one data bit. A data reading process is as follows. If the silicone tip scans the top of the polymer, the silicone tip falls into the hole, generating a short between the silicone tip and the conductor layer. An output voltage value is changed. An external voltage meter reads the changed value, to read a data bit.
    • 目的:提供一种数据存储装置,使数据读取速度随着数据读取速度的增加而减小一点,并获得更大的信噪比,从而解决了保留问题以及数据读取速度和S / N问题 比。 规定:数据写入过程如下。 导体层(34)形成在硅基底(35)的顶部上。 绝缘层(33)形成在导体层上。 当将电流施加到悬臂(32)的金属电极时,硅胶尖端(31)发热。 如果聚合物的要求部分被热量加热,则聚合物熔化。 穿过导体层表面的孔(38)形成在聚合物熔融的位置上。 该孔用作一个数据位。 数据读取过程如下。 如果硅胶尖端扫描聚合物的顶部,则硅胶尖端落入孔中,在硅胶尖端和导体层之间产生短路。 输出电压值变化。 外部电压表读取更改的值,读取数据位。
