![]() As a result, disk has replaced tape as the preferred medium for backup. It's quicker, though, to restore data from disk. In a disaster recovery scenario, as long as the tapes are far enough away from the affected data center, an organization can use them for restoration. ![]() Tapes are also easily movable, while disks are not as portable. Magnetic tape storage is also well-suited for archiving because of its durability, as it generally has a 30-year shelf life. Customers can count on that reliable product roadmap. The LTO Program has a defined schedule for upcoming releases, and it typically launches a new version every two to three years. With data volumes on the rise, magnetic tape is a strong option for high-capacity, long-term backup storage and archiving at a cost comparatively cheaper than disk. Barium ferrite is used in both enterprise tape from Oracle and IBM and Ultrium format tape from the LTO Consortium. The industry has largely moved from oxides as a recording material to barium ferrite, which is capable of delivering high recording data density because of its support for perpendicular magnetic recording. An LTO-8 tape drive and LTO-8 tape media. Improvements in track-following technology and giant magnetoresistive read/write heads increased the number of tracks that can be recorded on a tape. How magnetic tape worksÄata bits - magnetic states representing on and off - are recorded to a particulate medium bonded to a substrate of Mylar plastic. Sometimes, it is entirely replaced by object storage. Tape is often paired with object storage to address the need for lower-latency file access. Because oil exploration occurs outside the data center, tape is a good medium to transport data back from the field. ![]() The oil and gas industry has used tape for years to capture, transport and store valuable data.Scientific experiments that produce mass quantities of data in a few microseconds leverage tape's capacity and write speeds.Many motion picture production companies record their footage on tape after experiencing costly failures with both hard disk and flash.While tape can't compete with other storage media in terms of random access, there are still industries in which magnetic tape storage is a valuable storage technology. With tape archiving, there is no online copy for quick retrieval, as everything is vaulted for the long term. If the tape is part of a library, robotic selection and loading the right cartridge into a tape drive can add latency. While tape has largely been displaced as a primary and backup storage medium, it remains well-suited for archiving because of its high capacity, low cost and long durability. Magnetic tape is one of the oldest technologies for electronic data storage.
