DVD-R

A DVD-R is a type of blank DVD disc that allows data to be written only once. It uses an organic dye that, when heated by the laser of a DVD writer, changes to create permanent marks. These marks are then read by another laser.

The main difference lies in the recording technology. DVD-Rs use a less flexible recording format but are generally more compatible with older players. DVD+Rs offer faster burning and better error management, but may be less compatible with some older players. The choice will depend on your specific needs and the compatibility of your devices.

The standard capacity of a DVD-R is 4.7 GB. There are also dual-layer DVD-Rs (DVD-R DL) that can store up to 8.5 GB of data.

The recording speed is indicated by a number followed by 'x' (e.g., 16x). A higher speed means faster burning, but it is recommended to choose a speed slightly lower than the maximum speed supported by your writer and discs to ensure better recording reliability.

No, a DVD-R is a write-once medium. Once data has been written, it cannot be erased or modified. If you need a rewritable medium, you should opt for DVD-RWs.

You can burn a wide variety of data to a DVD-R, including video files (movies, personal videos), photos, music, important data backups, software, and any other type of digital file.
