The use and maintenance of magnetic cabinet

In real life, we often encounter: After reading a new disc, the disk often becomes very fast, and mosaics or unreadable discs often appear when watching. With various magnetic media such as sound tapes, tapes, video tapes, floppy disks, and optical discs, there are more and more materials for optical media, and the storage conditions for such data are relatively high. If the storage environment is not good, data loss may result. , save time and other issues.
The requirements of the disc protection for the external environment are mainly manifested in the following aspects:
1. Temperature and humidity. Temperature and humidity are important factors affecting the durability of electronic document carriers. Therefore, it is important to store the optical disc in a place where temperature and humidity are relatively stable. In general, the most favorable temperature for disc storage is 14°C to 24°C and relative humidity is 45% to 60%.
2. Dust. Dust can cause contamination and scratches on the surface of the disc, corrosion of the carrier, degradation, and breeding of mold. Therefore, to create a condition that reduces the amount of dust in the air, it is forbidden to directly touch the information section of the disc and put it back into the disc cartridge after use. When marking the disc, use an oily marker with a soft tip. Do not use a ballpoint pen or other hard tip to write on the surface of the disc because scratching the hard tip can damage the reflective layer of the disc.
3. Foreign magnetic field. The external magnetic field acting on the magnetic carrier can demagnetize or magnetize the magnetic coating, destroy the recorded information, and affect the readout effect. Therefore, the storage of optical discs should be kept away from magnetic fields. In the home, it is mainly away from some electrical appliances such as televisions, computers, and mobile phones.
4. Light and harmful gases. The reflective layer of the disc contains light-sensitive organic dyes, so do not put it in direct sunlight. Harmful gases are acidic and oxidizing, which can corrode and destroy the carrier, resulting in ageing and deterioration of the disc substrate, magnetic powder loss, and various stains, resulting in loss of information and damage to the disc body.
protective device"
The characteristics of the optical disc itself determine that it cannot be directly exposed to the outside world. It needs a certain protection “device” to install it. The magnetically shielded cabinet is a product commonly used on the market to store and protect the optical disc. In addition, if the number of optical discs is large, , You can also use a special anti-magnetic disc cabinet to store.
