1 "OPARG" to realize the high reliable optical archive systems Sumitaka Matsumura OPARG chair 1/25

2 Demand for digital data archive Usage of digital data has explosively been expanded. Recordable optical discs are expected to be reasonable and reliable media for long-term preservation of digital data. 2/25

3 Why Optical disc? Reasonable media cost Stable against storage environment change Low energy consumption for data preservation 3/25

6 How to realize a reliable system Two key issues for long-term digital data preservation using optical discs. a) Life time improvement of Disc for data preservation - the discs with high quality and high reliability, b) Quality improvement of initial data-writing on Disc the proper combination of dedicated media and drive. 6/25

7 Related Standard a) Life time improvement of Disc for data preservation - ISO/IEC16963: 2013 Information Technology -- Test method for the estimation of lifetime of optical media for long-term data storage b) Quality improvement of initial data writing on Disc - JIIMA (Japan Image and Information Management Association) TM Guidelines for inspection criteria and handlings of Blu-ray Disc for long-term preservation of electronic imaging documents" Ver. 1.0, Apr., JIS Z 6017: 2013 "Document management -- Long-term preservation for electronic imaging documents", Sep., JIIMA Certification has started Oct.,2014 7/25

8 Key technical points of JIS Z 6017:2013 Use Optical disc for long term data preservation Use proper combination of drive and disc to optimize initial data-writing conditions Verify digital data error to keep initial datawriting quality ---> Error count function is necessary for a drive Use optical disc with long expected lifetime estimated by ISO/IEC /25

9 Standardization has done, but how to realize? To realize the high reliable Optical Archiving system, three companies Pioneer, Mitsubishi Kagaku Media Victor Advanced Media have established the Optical Archive Group (OPARG) 9/25

10 What's OPARG OPtical ARchive Group Press release on Sep.,.26/ /25

11 OPARG objectives Realizing high reliability data writing and archiving with good partnership between disc and drive manufacturers Offering high reliable combination of dedicated media and drive Stepping up a relationship with system solution providers Applying media certification service and standards provided by official organizations as much as possible ADTC JIIMA etc. 11/25

12 OPARG structure Promotion activities Proposal of system solutions Leading standardization Reliability certification Collaboration with supporting companies ISO/IEC /25

13 OPARG essential components Superior professional disc strictly examined for high reliability and long-term archiving usage Superior professional drive composed of strictly select parts and having measurement functions compliant with JIS Z 6017:2013 Specific scheme to identify OPARG authorized disc and drive 13/25

14 Relationship with each standard OPARG specification provides further improvements for written data quality and compatibility in addition to JIIMA certification OPARG Spec. JIIMA Certification ISO/IEC JIS Z 6017 Standard JIIMA certification provides the actual operation to certify the initial datawriting quality based on JIS Z 6017, and it mandates the expected lifetime estimation of a disc conformed to ISO/IEC JIS Z 6017 specifies the technical criteria and operation method of initial data-writing and data migration for long term data preservation 14/25

22 OPARG Disc category expansion Professional archive Business archive Initial Recorded Signal quality Compliant with JIS Z 6017 Conform to OPARG Archive Disc Technical Regulations Compliant with JIS Z 6017 Acceptable Defects on a recording layer Compliant with JIS Z 6017 Adoption of alternative recording method Estimated Life-time of Disc Over 200 years Over 100 years For more wide industry use 22/25

23 Conclusion 1) Digital data archiving in industrial market will be one of the most important applications for optical disc system and expected to expand rapidly by world wide basis. 2) To realize the long-term preservation for electronic imaging documents, JIS Z 6017:2013 has been developed, and certification has begun from Oct And it is expected to be International standard in near future. 3) OPARG is the group offering the practical solutions to realize the high reliable optical archive systems based on JIS Z 6017:2013 and ISO/IEC 16963: /25
