The polycarbonate substrate is the main component of the optical disc, with excellent physical and chemical stability. It can endure high-precision recording processes and has good resistance to wear and scratching, ensuring long-term stability and durability of the disc. 2. Recording Layers The recording layer is the key part of storing information on the disc, typically made of organic dyes or metal materials. These materials have good photosensitivity, which allows them to undergo physical or chemical changes under the irradiation of laser light, thereby storing information on the disc. Additionally, the recording layer has a high storage density and good signal-to-noise ratio, ensuring reliable and stable data storage. II. Technical Characteristics The technical characteristics of recordable optical discs are mainly reflected in the following aspects: 1. Laser Recording Technology The core technology of recordable optical discs is laser recording technology. Information is written and stored by inducing physical or chemical changes in the recording layer through laser irradiation. Laser recording technology offers high accuracy, high speed, and high density, meeting the needs of different users. 2. High Storage Capacity With the continuous development of technology, the storage capacity of recordable optical discs has been increasing. This is mainly due to the advancement of optical technology and increased recording density. High-capacity recordable optical discs can meet the demand for more information and provide more possibilities for long-term data preservation. 3. High Durability Quality recordable optical discs should have high durability, able to endure frequent reading and writing operations as well as external environmental influences. Using high-quality substrate materials and advanced production technologies can ensure the durability and stability of the discs. Additionally, correct usage and maintenance can also extend the service life of recordable optical discs.
