More Issues and Solution
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 Where is Need to control storage environment “Long term storage with eco-friendly Data Loss Concern device”? Vulnerable to accidental environmental change
Optical Disc can solve these issues
