Therefore the projected lifetime is expected to be several hundreds of years. BDXL 100GB capacity makes archiving essential data easier for home users as well as business & enterprises users. MDISC BDXL discs incorporate titanium for added longevity. Combined with the MDISC patented “rock-like” recording layer this provides ultimate protection for you precious memories & data.
