Development of terabyte-class volumetric optical storage technology with nanoimprint thin optical disk - Maxell

It seems that Hitachi Maxell developed a system with 100 sheets of this stuck together on both sides and made it 940 GB. In the future it will be 100 TB for small type and 1000 TB (1 petabyte) for large type. It seems to be a substitute for tape backup, how much will it cost?
