To write data on a Blu-ray disk one must use a Blu-ray disk writer drive. Some DVD-R drives come with two lasers; one for burning files to the DVD and another one for reading and writing files on a Blu-ray disc.  Just like DVDs, Blu-ray disks can be rewritten and re-recorded with data multiple times. However, some types of Blu-ray discs such as BD-R LTH can only be written once and cannot be erased.

Lost data or deleted files on a BD-RE (Blu-ray Disc Recordable Erasable) disc cannot be recovered back with a data recovery program. But as long as the disc is not damage, there is a slight chance that you might be able to backup burned files after damaging the disc with scratches. Disk Drill is a data recovery software that can only be used to recover deleted files on storage media devices such as Compact Flash, Flash Disks, XD-Picture Cards, Memory Cards, External hard drive, etc.
