DVD-R can be used to record data. Once DVD-R has been written to, it cannot be written to again. Data is written to on disc by a laser. DVD recordable uses dye to store the data. During the burning of a single bit, the laser’s intensity affects the reflective properties of the burned dye. By varying the laser intensity quickly, high density data is written in tracks.
