Computers can be said to be one of humanity's greatest inventions, and many other inventions that have changed our lives have derived from computers, such as the internet, videos, games, etc. Now, in addition to processing data to make work more convenient as before, computers have also changed our way of life. We know that computers belong to electronic products, and with the changes of the times, people's understanding of electronic products is generally light, small, and fully functional, which means that modern electronic products, including many computer accessories, must contain more components while being compact, so high precision is essential.

Computer optical drives have long been a component of computers, designed to read disc data and display the content on the screen through the computer's operating system. Although the internet is very developed now, allowing us to watch videos and listen to music online, computers are still equipped with optical drives, which remain an indispensable part of computers.

As for how the optical drive reads the content on the disc, this brings us to the laser head of the optical drive, which can be considered the core part of the optical drive, specifically responsible for reading data from the disc. If the laser head is damaged, it is generally necessary to replace the entire optical drive, as replacing just the laser head is not cost-effective and is quite troublesome. If the manufacturer damages the laser head during production and assembly, it means the entire optical drive is scrapped.

In situations that require high-precision assembly, smart screwdrivers are the most suitable. As long as the relevant parameters required for assembly, such as torque, are set, the smart screwdriver can tighten every screw of the same product according to the requirements. Moreover, after the operation is completed, the screwdriver's controller can save the data records of each tightening, which can be analyzed by relevant personnel to monitor product quality and even detect the quality of raw materials.

The future is an era of big data, and even simple tasks like tightening screws require big data records to identify areas for improvement. Only through continuous refinement can we create a better future!
