5PK DVD-RW Media 4.7GB Singlesided Rewriteable - 2X Jewel Case

Organize, archive and share your memories with TDK recordable DVD media. You get the ability to form ultra-small data marks to achieve full 4.7GB capacity while using only the groove areas of the disk for recording. Groove-only data format, in combination with ample reflectivity makes TDK DVD-RW the first rewritable DVD disc to achieve playback compatibility in DVD-ROM and DVD-Video players. TDK DVD-RWs use metallic alloy that changes between the crystalline and amorphous states in response to the heat generated by a laser for phase-change recording on DVD-RAM. The changes in reflectivity exhibited by the alloy in its crystalline and amorphous states are read as data.
