ODA is creating a hype in video archiving market. But what exactly is ODA?
ODA expanded form is Optical Disk Archive and is a storage technology that was introduced by the Sony Corporation. It uses removable cartridges, where each cartridge holds 11 or 12 high density optical discs to store data. It can be as small as a single unit and can be scaled to petabytes library.
As data innovation keeps on advancing, organizations in each industry are working with consistently developing amounts of computerized information. Sony’s Optical Disc Archive system has been developed to help these organizations achieve safe, long-term storage of video, photos, text, and other important digital assets. Telecasters are holding expanding amounts of profitable and vital video, for example, memorable video and finish bundle content that they can’t stand to lose. But all work environments are at risk of network and server failures, natural disasters, and other unforeseen data-destroying events. Archive system significantly reduces vulnerability to such events, helping to ensure that valuable data will remain secure for many generations.
Sony’s archiving solution offers reliable and economical long-term storage suitable for broadcast stations, educational institutions, federal and local government agencies, banks, and many others.
International Data Corporation (IDC), a US-based research, analysis and advisory firm, projects that worldwide stored data will reach 44 zetta bytes (44 x 1021 bytes) in 2020—suggesting that demands on data centers are growing very rapidly. Where 1 ZB = 1,099,511,627,776 GB
ODA has all the advantages of optical disk data access methods. It uses same random access methods to access data stored across the physical disc thereby reducing the seek-time unlike LTO which access data sequentially. Gen 2 drive unit holds four laser head assemblies, each containing two heads—for a total of eight laser heads. With two assemblies positioned at the top and two at the bottom, the system can read/write both sides of the disc at the same time. Sony’s original high speed technology provides an average read rate of 2 Gbps (250 MB/s), and an average write rate of 1 Gbps (125 MB/s) with verify—allowing the system to deliver very rapid processing even while serving as a robust, long-term data store.
An optical disc loads into an optical drive. This drive uses a semiconductor laser to write data onto the disc and to read data (by reflection) from the disc. Because lasers are used, no contact is made with the disc surface during reading and writing.
These discs also offer excellent tolerance to ambient environment, holding data reliably for over 50+ years under normal temperature and humidity conditions even without Air-conditioning. This not only achieves —reduced operating costs but facilitates a reduced environmental footprint.
New-generation disc system support backward compatible as conventional optical discs, the need for data migration is essentially eliminated. The disc is very durable and water-resistant. Cartridges have passed rigorous quality testing including dust tests, UV exposure tests, abrasion tests, toxic gas tests, and water resistant tests to ensure the robustness and reliability required for professional use.
ODA uses the Universal Disk Format (UDF), an open, vendor-neutral and versatile file system for computer storage media, widely used with optical media.
