How many years does a typical disc last?

Ordinary CD is an aluminum reflective layer, the natural life span is about 50 years, and the actual life is 20-30 years, provided that it is not a burning disk.

The theoretical lifespan is about 75 years, and the actual lifespan is about 35-50 years. VCD and CD are about the same.

These are all based on theory, and the life of gold-plated discs is higher.

Pirated Disc LifeMinimum Disc Lifespan The lifespan of a disc depends on 3 factors:

1. Physical and chemical properties of the disc itself The disc is composed of three parts: a polymeric plastic (polycarbonate) layer, an aluminum film layer and a protective coating. If the ambient temperature is too high or too low, the aging of the plastic will be accelerated, and the aluminum film will slowly oxidize when it comes into contact with the air. In addition, the data of optical discs can only be read, cannot be rewritten, and cannot be repaired or identified after being damaged, and can only be discarded, which is very different from disks.

2. Daily maintenance The disc has a high usage rate in many applications, and improper use and incorrect maintenance methods will shorten the life of the disc. Disc cases, CD cleaning brushes, disc cleaning machines and optical drive cleaning discs have brought great convenience to us in using and maintaining optical discs.

3. With the update of computer technology, the optical drive is turning faster and faster, but the "eyesight" is getting worse and worse, and many disks that can be read can not be read now.

10 years for ordinary discs, 50 years for silver discs, and 100 years for gold discs. This is just the actual theoretical data, but because the disc is disturbed by external factors such as moisture and electromagnetic fields during storage, the data in it will be destroyed, resulting in the disc can not be used normally.

What is a disc? If it is burned, the lifespan is very short. The rest depends on how often you use it. If you don't need it once a year, you can use it for many years. If I use it regularly, I estimate that it will only be half a year. The quality of the discs is not very good now.

It's a very abstract question, and if you use a brick, it will only last a few minutes, and if you use it with care, you won't want to use it.

Under normal circumstances, it can be kept undamaged for 2 years.

It is stored for 50 years, that is, it is put away without use, and it is moisture-proof, heat-proof, cold-proof and pressure-proof.

After 10 years, some discs love to fall off!

It depends on how you use it, basically the quality of society is not very good now. You're blessed to be able to reach half a year!

There are all kinds of answers.

It generally depends on the quality of the disc.

It's up to you, ah, it can be used for a long time.

It is used frequently, and it will not be able to grind in less than a year

Theoretically, it's been a long time.

Generally in 10 years.

If you use it more, your ability will drop significantly in a few years.

Theoretically it should be used for a lifetime without a problem :)

The manufacturer indicates that it can be stored for 5 years or 10 years.

Jerome, executive producer at Cocottes Minute in France, uses a combination of hard and disk to save dailies. However, he is still not sure whether this method of storage is the best option.

He said he didn't know how long he could keep the images, and the disc manufacturers just said they could keep them for five, 10 or 15 years, but they didn't really make a commitment to how long they could store the film on the disc.
