As the demand for human data increases, the requirements for data storage are also increasing. Optical Data Storage (ODS) is a light -based storage method, commonly used in DVD, which is low -cost and very durable.However, ODS usually stores data with a single layer, and the amount of data that can be stored is limited.
Academician of Shanghai University of Science and Technology , Wen Jing and the Shanghai Institute of Optical and Precision Machinery of the Chinese Academy of Sciences Researcher Ruan Hao published a research paper on the top international academic journal Nature : A 3D Nanoscale Optical Disk Memory with Petabit Capacity.
This paper describes a new method that stores more data in the disc. This method uses three -dimensional instead of storage data. The data storage volume can reach the amazing Bitbi Bit (Petabit) level, that is, 100 billion Bill Bit (1015 BIT).
In this study, Wen Jing , Ruan Hao , Gu Min and others developed a new method to use the three -dimensional optical data storage (ODS) structure..This method uses a new storage medium called AIE-DDPR , which is made of induced luminous dye by mixing into the light-resistant film.This enables the film to read and write on the nano -scale.This film consists of an absorption molecules (photogenic agent) and a high -allergy molecules to obtain writing data.
The research team uses 54 nanometer to record the laser -dimensional laser storage data.EssenceThe research team also found that the quality stored in a thin film is equivalent to the data that is closer to the surface.
Blank AIE-DDPR CD-ROM Optical Writing and Reading Principles and Production Process
The research team pointed out that the workflow of producing the AIE-DDPR disc is compatible with existing DVD methods, indicating that the production of these film may have large-scale possibilities and economic feasibility.The paper also pointed out the limitations of some technology, including the speed and energy consumption of the process.
