Optical Disc Archive (ODA) is an archival storage technology developed by Sony. A single cartridge is designed to hold as many as 12 optical discs, each of which are similar to, but not directly compatible with, Blu-ray or Blu-Ray-BDXL systems, with total capacities per cartridge as high as 5.5 TB. Fabrication of the optical discs is licensed to TDK but primarily fabricated and developed by Sony and Panasonic.

It is part of Sony's proprietary PetaSite data archival library system, which was based on SAIT2 & LTO2 linear tape drives, in partnership with IBM from 1998~2012, when it was phased out for optical based media. Marketed as a longer life and more durable competitor to the popular tape based Linear Open Tape (LTO) storage systems using a similar removable cartridge system, where each cartridge holds 12 optical discs, or 6,420 discs per 42U rack, the first generation were single sided discs and re-writable up to 1.5 TB using Sony's well known Professional Disc used in XDCAM cameras and on-site archival. The generation 3 version of the cartridge, using the Sony and Panasonic jointly developed archival discs (AD) each cartridge has a total capacity of 5.5 TB. This uses 11 optical discs, 3 layers on each side, at 500 GB per disc,[1] with next generation planned to reach 1 TB a disc or 12 TB a cartridge.[2]

Overview

Sony Optical Archive is marketed as an offline, online, nearline, cold archival and one way data storage solution for broadcasting, education, and legal institutions for long term scaled use and easy digital access.

Media and hardware lifecycle and reliability benefits compared to tape-based media include the elimination of friction-induced media and tape head wear and shedding, and a humidity-proof polycarbonate media substrate (similar to M-Disc) which is not affected by electromagnetic/gamma/alpha radiation, most chemicals or fluid contaminants. Lastly, the usage of a standard 405 nm optical laser (The same as used in current Blu-ray & Blu-Ray BDXL reader/writers) helps ensure long-term hardware component availability to facilitate long-term data retrieval.

Along with its large data storage capacity, this makes the format ideal for protection of large datasets against unexpected events like natural disasters. For example, since the 2011 Tōhoku earthquake and tsunami and the cessation of production of the HDCAM & HDCAM SR master format as well as a broadcast industry migration to file based digital media delivery, this overall resulted in a higher demand for reliable backup and digital access to media libraries leading to wide adoption of the Optical Archive system in Japan for backup of 4K and HDR content.[3]

The Optical Archive cartridge system can be used on the desktop, or in scaled networked storage using the PetaSite optical jukebox. The storage jukeboxes take up 7U of standard rackmount space with 30 a cartridge master unit (ODS-L30M) and 60 cartridge (ODS-L60E) and 100 (ODS-L100E) cartridge expansion units for a combined total of 535 cartridges or 6,420 discs per 42U rack, equaling a current 2.9425 PB of total storage (Using 5.5 TB cartridges).

History and development

In 1996 "PetaSite" was trade marked by Sony Kabushiki Kaisha.[4] (renewed in 2018)

In 2001 "PetaSite was announced to the global market"[5]

In 2004 the CSM60, CSM100, CSM200 with 50~108 TB via SAIT2/LTO2 tape cartridges was launched[6]

In 2006 Sony & NEC start a joint venture in Optical Archives and Blu-ray/DVD reader/writer units founding

2009~Current IBM/Sony stop sale of the CSM and SAIT2/LTO2 based systems, still providing service support for existing systems.

In 2012 Optical switchover Sony released their first desktop ODA cartridge readers[7] for consumer/prosumer desktop use (USB 3.0 Type B) during the NAB Show with the first units shipping in February 2013 shifting the PetaSite brand entirely to optical based media.

Sony Corporation and Panasonic Corporation on announced on 10 March 2014 their cooperation in producing a new media trademarked as Archival Disc. The Archival Disc media[8] will be used in future Optical Disc Archive Media to achieve at least 12 TB of storage.

In 2015 Sony strategically acquired Optical Archive Inc. that was owned by Frank Frankovsky,[9] giving Sony technology for current automatic store and retrieval systems, the foundation of the modular 7U rack-mount based system PetaSite uses today.

In 2020, Sony released the third generation system,[10] with new 5.5 TB cartridges and an updated capability to the PetaSite ecosystem alongside desktop readers with USB Type-C 3.2 interfaces.[2] The read speed is increased to 375 MB/s and the write speed (with verification on) to 187.5 MB/s.

In 2023, The Sony web site shows all of the ODA drives and PetaSite libraries as discontinued products. [citation needed]

The PetaSite system has datacenter interconnect systems via Copper (Ethernet 1~10GbE) or Fiber Optical links (SFP+ 10GbE~100GbE) with desktop interfaces using USB 3.2 Gen 2 (20 Gbit/s) with 19.5v DC power.

Software

Sony Optical Archive & PetaSite uses a content management software[11] simply called File Manager[12] currently in its second major revision "File Manager 2"
