高分子数据存储的研究进展
Advances in Macromolecular Data Storage
摘要：
我们建议开发一种新的信息存储方法，以取代磁性硬盘驱动器和其他辅助/备份数据存储工具。所提出的方法将数PB的用户数据存储在方糖（1 cm 3）中，并且可以以数百兆比特/秒的速度读取/写入该信息。数字信息以长的大分子的形式记录和存储，该大分子由至少两个碱基A和B组成。(This将类似于由四种核酸G、C、A、T构建的DNA链）。大分子最初作为空白板进入系统。一个大分子，比如说，有10,000个相同的碱基，以AAAAA的形式存在...... AAA可以用来记录100字节的用户数据块（包括调制和纠错编码），尽管在这种空白状态下，它只能表示空序列00000......。000.假设这一串空白的A被拖到扫描隧道显微镜（STM）的原子级针尖前。当根据用户数据的1 kB块的0和1的序列将电脉冲施加到针时，所选择的A分子将被转换成B分子（例如，A的一部分将被折断并丢弃）。生成的字符串现在以AABABBA.的形式对用户数据进行编码。巴布。同样的STM针可以随后读取记录的信息，因为当股线通过针下时，A和B会产生不同的电信号。大分子现在代表一个数据块，将被存储在方糖内的“停车场”，然后根据需要被带到读取站。数百万个停车点和数千个读/写站可以集成在微制造的方糖内，从而以一种方案提供对PB级用户数据的访问，该方案受益于同一三维微结构化设备内数千个读/写站的大规模并行性。
英文摘要：
We propose to develop a new method of information storage to replace magnetic hard disk drives and other instruments of secondary/backup data storage. The proposed method stores petabytes of user-data in a sugar cube (1 cm3), and can read/write that information at hundreds of megabits/sec. Digital information is recorded and stored in the form of a long macromolecule consisting of at least two bases, A and B. (This would be similar to DNA strands constructed from the four nucleic acids G,C,A,T.) The macromolecules initially enter the system as blank slates. A macromolecule with, say, 10,000 identical bases in the form of AAAAA....AAA may be used to record a kilobyte block of user-data (including modulation and error-correction coding), although, in this blank state, it can only represent the null sequence 00000....000. Suppose this blank string of A's is dragged before an atomically-sharp needle of a scanning tunneling microscope (STM). When electric pulses are applied to the needle in accordance with the sequence of 0s and 1s of a 1 kB block of user-data, selected A molecules will be transformed into B molecules (e.g., a fraction of A will be broken off and discarded). The resulting string now encodes the user-data in the form of AABABBA...BAB. The same STM needle can subsequently read the recorded information, as A and B would produce different electric signals when the strand passes under the needle. The macromolecule now represents a data block to be stored in a "parking lot" within the sugar cube, and later brought to a read station on demand. Millions of parking spots and thousands of Read/Write stations may be integrated within the micro-fabricated sugar cube, thus providing access to petabytes of user-data in a scheme that benefits from the massive parallelism of thousands of Read/Write stations within the same three-dimensionally micro-structured device.
