• The Blu-ray Disc™ is the de facto standard for large-capacity optical discs, and is supported by about 170 major corporations, assuring long-term readability.
  • A large variety of applicable equipment offers a wide range of reading environments.
Blu-ray Disc™ Advantages as an Archive Media


  • Blu-ray Disc™ is less likely to be affected by humidity, temperature and light, and resists changes over time, so it is ideal media for archiving long period.
  • Unlike magnetic tape and HDDs, there is no contact between the optical pickup (OPU) and the disc, so it maintains excellent durability even after repeated reading and writing.
Panasonic Blu-ray™ discs have an archival life of more than 50 years, in contrast to an HDD’s 5 to 10-year and magnetic tape’s 15-20-year archival life. This allows data to be stored for longer periods of time without the need for data migration.


  • Unlike media such as magnetic tape, the WORM (Write Once Read Many) BD-R physically prevents overwriting
  • With its long-term storage ability, the BD-R eliminates security risks because data migration is unnecessary
  • BDs have a serial number and an ID (recorded in the Burst Cutting Area (BCA) ), making it easy to verify the authenticity of the media itself

Keep the total cost of operation low

  • Unlike a RAID system, where the motor is constantly rotating even when it is not in use, offline archiving is possible with Blu-ray™ discs without the need for constant powering, to save on the electrical bill.
  • Air conditioning is not required for media storage, so there are no air conditioning costs involved.
  • Data migration is not required, so the costs related to migration, such as replacing devices, are not incurred.

Green Media

  • As data can be managed offline, the system does not have to be constantly powered, making it environmentally friendly.
  • Air conditioning is not required, so power consumption is reduced and CO2 emission is lowered.
  • Data migration is not required, so large amounts of waste products are not generated by having to replace devices.
