Disk storage is a general category of storage mechanisms where data is recorded by various electronic, magnetic, optical, or mechanical changes to a surface layer of one or more rotating disks. A disk drive is a device implementing such a storage mechanism. Notable types are the hard disk drive (HDD) containing a non-removable disk, the floppy disk drive (FDD) and its removable floppy disk, and various optical disc drives (ODD) and associated optical disc media.
Tandberg Data GmbH is a company focused on data storage products, especially streamers, headquartered in Dortmund, Germany. They are the only company still selling drives that use the QIC and VXA formats, but also produce LTO along with autoloaders, tape libraries, NAS devices, RDX Removable Disk Drives, Media and Virtual Tape Libraries.
Western Digital Corporation is an American computer hard disk drive manufacturer and data storage company, headquartered in San Jose, California. It designs, manufactures and sells data technology products, including storage devices, data center systems and cloud storage services.
A magneto-optical drive is a kind of optical disc drive capable of writing and rewriting data upon a magneto-optical disc. Both 130 mm (5.25 in) and 90 mm (3.5 in) form factors exist. In 1983, just a year after the introduction of the Compact Disc, Kees Schouhamer Immink and Joseph Braat presented the first experiments with erasable magneto-optical Compact Discs during the 73rd AES Convention in Eindhoven. The technology was introduced commercially in 1985. Although optical, they normally appear as hard disk drives to an operating system and can be formatted with any file system. Magneto-optical drives were common in some countries, such as Japan, but have fallen into disuse.
Quantum Corporation is a data storage, management, and protection company that provides technology to store, manage, archive, and protect video and unstructured data throughout the data lifecycle. Their products are used by enterprises, media and entertainment companies, government agencies, big data companies, and life science organizations. Quantum is headquartered in San Jose, California and has offices around the world, supporting customers globally in addition to working with a network of distributors, VARs, DMRs, OEMs and other suppliers.
Digital Data Storage (DDS) is a computer data storage technology that is based upon the Digital Audio Tape (DAT) format that was developed during the 1980s. DDS is primarily intended for use as off-line storage, especially for generating backup copies of working data.
Digital Linear Tape is a magnetic-tape data storage technology developed by Digital Equipment Corporation (DEC) from 1984 onwards. In 1994, the technology was purchased by Quantum Corporation, who manufactured drives and licensed the technology and trademark. A variant with higher capacity is called Super DLT (SDLT). The lower cost "value line" was initially manufactured by Benchmark Storage Innovations under license from Quantum. Quantum acquired Benchmark in 2002.
Advanced Intelligent Tape (AIT) is a discontinued high-speed, high-capacity magnetic tape data storage format developed and controlled by Sony. It competed mainly against the DLT, LTO, DAT/DDS, and VXA formats. AIT uses a cassette similar to Video8. Super AIT (SAIT) is a higher capacity variant using wider tape in a larger, single-spool cartridge. Both AIT and SAIT use the helical scan method of reading and writing the tape.
Linear Tape-Open (LTO) is a magnetic tape data storage technology originally developed in the late 1990s as an open standards alternative to the proprietary magnetic tape formats that were available at the time. Hewlett Packard Enterprise, IBM, and Quantum control the LTO Consortium, which directs development and manages licensing and certification of media and mechanism manufacturers.
The 8 mm backup format is a magnetic tape data storage format used in computer systems, pioneered by Exabyte Corporation. It is also known as Data8, often abbreviated to D8 and is written as D-Eight on some Sony branded media. Such systems can back up up to 60 GB of data depending on configuration. The cassettes have the same dimensions and construction as the cassettes used in 8 mm video format recorders and camcorders.
The 3480 tape format is a magnetic tape data storage format developed by IBM. The tape is one-half inch (13 mm) wide and is packaged in a 4 in × 5 in × 1 in cartridge. The cartridge contains a single reel; the takeup reel is inside the tape drive.
EMTEC is part of the Dexxon Group headquartered in Gennevilliers, France, and markets consumer computer data storage products and other computer related consumables. Dexxon Group's North American subsidiary, Dexxon Digital Storage Inc. is located in Lewis Center, Ohio. EMTEC evolved from BASF Magnetics producing magnetic tapes. Between 1998 and 2002 all of BASF's cassette lineup were rebranded EMTEC. While cassette manufacture has since ceased in 2005, and reel-to-reel tape operations were sold to RMGI, EMTEC continues to manufacture other recordable media such as optical discs, MiniDV and VHS cassettes, USB 2.0 and 3.0 Flash Drives. The Flash drives come in a variety of storage sizes. Distribution channels have decreased and EMTEC presence in the market is a shadow of its former BASF self. Since its sale by BASF, EMTEC has undergone several transformations.
VXA is a tape backup format originally created by Ecrix and now owned by Tandberg Data. After the merger between Ecrix and Exabyte on 17 November 2001, VXA was produced by Exabyte Corporation. On November 20, 2006, Exabyte was purchased by Tandberg Data that has since stopped further development of the format.
Storage Technology Corporation created several magnetic tape data storage formats. These are commonly used with large computer systems, typically in conjunction with a robotic tape library. The most recent format is the T10000. StorageTek primarily competed with IBM in this market, and continued to do so after its acquisition by Sun Microsystems in 2005 and as part of the Sun Microsystems acquisition by Oracle in 2009.
Overland Storage is a wholly owned subsidiary of Sphere 3D Corp. It has acquired Tandberg Data shortly before being acquired by Sphere 3D itself. The two subsidiaries were later rebranded under the common Overland-Tandberg brand.
Magnetic-tape data storage is a system for storing digital information on magnetic tape using digital recording.
Qualstar Corporation is an American manufacturer of magnetic tape data storage products, based in Simi Valley, California. It was founded in 1984 as a 9 track tape drive manufacturer, and now makes tape library products. The company sold its last 9 track tape drive in 2006 and as of March 2006 has sold all remaining parts inventory to Vinastar, an aftermarket vendor.
The Linear Tape File System (LTFS) is a file system that allows files stored on magnetic tape to be accessed in a similar fashion to those on disk or removable flash drives. It requires both a specific format of data on the tape media and software to provide a file system interface to the data.
Tallgrass Technologies Corporation was the first manufacturer to offer a hard disk drive product for the IBM PC. Tallgrass was a Kansas City based microcomputer hardware and software company founded in December 1980 by David M. Allen. The hard disk drive product was initially sold in Computerland stores, alongside the original IBM PC. Tallgrass added tape-backup systems to its product line in 1982.
