The difference between a burning optical drive and a non burning optical drive

The burner is CD-R, which is the abbreviation of English CD recordable, which can be divided into two types: one is CD burning, and the other is *** burning. The CD-R disk used is generally 650MB.

The information recorded on it is the same as that of a general CD disc, and it also uses the reflection of the laser beam to read the data, so the CD-R disc can be read on the CD-ROM, but the difference is that the CD-R disc can be written once.

When burning a CD-R disc, the recorder emits a high-power laser to focus on a specific part of the CD-R disc, so that the organic dye layer of this part produces a chemical reaction, so that this part cannot reflect the laser emitted by the optical drive, which is equivalent to the "concave surface" on the traditional CD disc; The place that is not illuminated by the high-power laser can reflect the laser according to the *** layer, which is equivalent to the "non-concave" on the traditional CD disc, so the engraved disc is basically the same as the reading principle of ordinary CD ROM.

The CD-R disc uses organic dyes as the primary material for the recording layer. At present, the most common ones on the market are green and gold discs, which are made of two organic dyes, cyan blue and golden yellow, respectively. In addition, there is a blue disc on the market, which uses an organic dye called azo that uses silver as a reflective layer.

Which platter is better? Many people think that the use of gold plates has a good effect and high quality, but in fact, this view is very one-sided, and each plate has its own characteristics. When it comes to choosing a CD-R platter, all three types of platters can be purchased with confidence.

At present, most recorders support not only the disk at once method, but also the track at once writing mode. When using the whole disk burning method, the user must write all the data to the CD-R disk at once, and if the data prepared is small, burning a disk will inevitably cause a lot of waste. This waste can be avoided by using orbital engraving, which allows a single CD-R disk to be burned multiple times if there is extra space.

There is also a CD-RW burner and platter on the market, which can be rewritable and can be erased more than 1,000 times.

It should be noted that both CD-R and CD-RW require the help of special burning software to record data on the disk. For example, Easy-CD Pro, etc., this kind of software is usually shipped with the purchase of a recorder.

At present, the burner on the market** has dropped very low. Recorders are mainly used for data exchange and backup.

One can burn discs, and the other cannot
