This article mainly introduces whether the CD can be repeatedly burned in the computer, which has certain reference value. Interested friends can refer to it. I hope you will have a lot of harvest after reading this article. Let Xiaobian take you to understand it together.

CD ROM and DVD R (or DVD+R) are disposable discs and cannot be burned repeatedly. Disc labels CD-RW, DVD-RW (or DVD+RW) are rewritable discs that can be burned repeatedly.

CD is divided into a variety of, take the common we burn DVD CD is divided into: DVD-R, DVD-RW, DVD+R, DVD+RW.

What is the difference between these types of CDs? Which types of CDs can be reused? How can I erase the CD and burn it again if I burn it repeatedly?

Optical discs use optical information as the carrier of storage. An object used to store data. It is divided into non-rewritable optical discs, such as CD-ROM, DVD-ROM, etc., and rewritable optical discs, such as CD-RW, DVD-RAM, etc.

DVD-R is called DVD-Recordable (recordable DVD), and in order to distinguish it from DVD+R, the industry defines it as Write Once DVD (write-once DVD). DVD-R/RW is a pioneering DVD recording format supported by Toshiba, Hitachi, NEC, Samsung and DVD FORUM. However, unlike CD-R, DVD-R currently comes in two types: Authorizing and General. The main physical difference between the two is the wavelength of the recording laser, so it requires a dedicated burner to write to it. However, once the recording is complete, it can be played on a traditional DVD player.

DVD-RW is called DVD-Rewritable (rewritable DVD), but in order to distinguish it from DVD+RW, the industry defines it as Rerecordable DVD (recordable DVD). The DVD-RW standard was proposed by Pioneer in 1998, and received strong support from DVD Forum, whose members include Apple, Hitachi, NEC, Samsung and Panasonic, and completed version 1.1 of the official standard in mid-2000. DVD-RW products were originally positioned as consumer electronics products, mainly providing VHS video tape similar functions, which can record high-quality multimedia video information for consumers. However, with the development of technology, DVD-RW's functions have slowly expanded into the computer field. The main difference between version 1.1 and version 1.0 is that it adds support for CPRM copyright protection technology.

DVD+R (Digital Versatile Disc Recordable) is a recordable disc format. The nominal capacity of a single layer is 4.7GB, and the actual capacity is 4.38G=4482.625MB=4,700,372,992 bytes (a total of 2,295,104 segments, each segment containing 2,048 bytes). The nominal capacity of the dual layer is 8.5GB, and the actual capacity is 7.96G= 8,152 MB=8,547,991,552 bytes (4,173,824 segments, each segment containing 2,048 bytes).

DVD+RW is now available in DVD-R/DVD-RW and DVD+R/DVD+RW formats. At present, DVD-R, DVD+R, DVD-RW, DVD+RW, DVD-R DL, DVD+R DL, DVD-ROM and DVD-RAM, which are not common in domestic market, are more common in domestic market. Here is a detailed description of the differences between these formats.

DVD-R/RW is one of the DVD recording technologies developed by Pioneer Corporation of Japan and certified by DVD Forum (the current DVD format standard is mainly determined by this organization). DVD-R stands for DVD-Recordable, which is different from DVD+R and is defined as Write Once DVD. DVD-RW is called DVD-Rewritable (rewritable DVD), which is different from DVD+RW and is defined as Rerecordable DVD (rewritable DVD). At present, the market price of DVD-R format discs varies from 2 yuan to 10 yuan due to different brands and packages, while the price of rewritable DVD-RW discs is mostly around 20 yuan.

DVD+R/RW was developed by the DVD+RW Alliance (a rival DVD standards-setting organization to the DVD Forum mentioned above), which was co-founded by Sony, Philips and HP. To distinguish it from DVD-R/RW, DVD+R is called DVD Recordable, DVD+RW is called DVD Rewritable. DVD+R/RW and DVD-R/RW are only different in format, so the price difference is not much.

DVD+/-R DL is a single-sided double-layer recording (DVD+/-Recordable Double layer) compared to the ordinary single-sided single-layer 4.7G, with two storage layers, compared to the ordinary single-sided single-layer recording disk storage capacity expanded to 8.5G, but due to technical problems, the production of such disk manufacturers are few.

Thank you for reading this article carefully. I hope that the article "Can CDs be burned repeatedly in computers" shared by Xiaobian will be helpful to everyone. At the same time, I hope that everyone will support you a lot and pay attention to the industry information channel. More relevant knowledge is waiting for you to learn!
