Optical Disc can solve these issues

Short Life Format life is limited(Tape:7.5yrs)

Media life is limited(HDD:3-5yrs,Tape:20yrs)

High Cost Migration at every 3 to 5 years

Need to control storage environment

Data Loss Concern Vulnerable to accidental environmental change

Where is

“Long term storage

with eco-friendly

device”?

More Issues and Solution


Why Optical Disc？

Longer Life, Lower Cost!

Not need Air Conditioner

Optical Disc can keep Data for 50 years

without air conditioning in all the cities in the world


Why Optical Disc？

Free from Data Loss Concern


Robustness against disaster

Higher resistance against sea water

Kept Blu-ray™ Disc for 5 weeks under

the sea water

Played back by Blu-ray™ player without

any problems

Higher resistance against electromagnetic

waves and magnetic fields

Data on the disc is recorded without electric/magnetic properties

Not affected by super solar storm
