The first-string advantageousness of DVD-RW concluded DVD-R

Standard DVD-R/RW compatible drives use a 650 nm red semiconductor device laser diode. The average control swallow rating is 250 mW to 4000 mW. Power swallow varies independency on the write speeds and double ply support. Higher speed drives call for to a greater extent control for increased data throughput, and double ply disks call for to a greater extent control to penetrate to the second ply of data.
