Glass hard drive principle

The principle of glass hard drive is based on laser interference and holographic technology, which uses laser beams to illuminate the glass substrate and encodes data into three-dimensional pixels through interference patterns. These pixels form an interference pattern on the glass surface with dimensions on the order of microns, and each pixel contains binary information of the data. Due to the stability and durability of the glass substrate, the data stored in it can be read using an optical microscope. Glass hard drive is a high-density data storage device based on laser interference and holographic technology. It uses the stability and durability of the glass substrate to achieve long-term storage and high-density storage of data.

Long-term storage and high-density storage. The following will introduce the principles, characteristics, manufacturing process and application fields of glass hard drives in detail.

1. The principle of glass hard drive

The principle of glass hard drive is based on laser interference and holographic technology. It uses laser beams shined onto a glass substrate to encode data into voxels through interference patterns. These pixels form an interference pattern on the glass surface with dimensions on the order of microns, and each pixel contains binary information of the data. Due to the stability and durability of the glass substrate, the data stored in it can be read using an optical microscope.

When reading data, the same laser beam used when writing data needs to be used to decode the interference pattern stored in the glass substrate through holographic technology. The decoded data can be read and analyzed with an electron microscope or optical spectrum analyzer.

2. Characteristics of glass hard drive

Glass hard drive has the following characteristics:

1. High-density storage: Glass hard drive can use laser interference and holographic technology to achieve high-density storage. A large amount of data can be stored per unit area.

2. Strong durability: The stability and durability of the glass substrate allow data to be stored in high temperature, high pressure, and high humidity environments for a long time without being lost due to changes in time and environment.

3. High reliability: Since glass hard drives do not rely on any mechanical movement or magnetic materials, they have high reliability and stability and will not lose data due to mechanical wear or magnetic field changes.

4. Can work in harsh environments: Due to the durability and reliability of glass hard drives, it can work in harsh environments, such as high temperature, low temperature, strong magnetic field, strong radiation and other environments.

3. Manufacturing process of glass hard drive

The manufacturing process of glass hard drive mainly includes the following steps:

1. Glass substrate preparation: select a transparent glass substrate, and Polishing and cleaning are performed to remove surface impurities and imperfections.

2. Laser interference pattern production: Using laser interference technology, interference patterns are produced on the glass substrate, and these patterns will be used to encode data.

3. Data writing: Use a laser beam to illuminate the interference pattern and write data into the glass substrate. During this process, the intensity and irradiation time of the laser beam will be precisely controlled to ensure the correct writing of data.

4. Holographic image reading: Use the same laser beam used when writing data to decode the interference pattern stored in the glass substrate through holographic technology. The decoded data can be read and analyzed with an electron microscope or optical spectrum analyzer.

5. Encapsulation protection: Encapsulate and protect the glass substrate with data written on it to avoid interference and damage to the data from the external environment.
