A tape drive is a data storage device that reads and writes data on a magnetic tape. Magnetic tape data storage is typically used for offline, archival data storage. Tape media generally has a favorable unit cost and a long archival stability.
Tandberg was an electronics manufacturer located in Oslo, Norway and New York City, United States. The company began in the radio field, but became more widely known for their reel-to-reel tape recorders as well as cassette decks and televisions. The original company went bankrupt in 1978, after a sharp financial downturn. The following year, the company re-formed whilst their data division was split off as Tandberg Data, including the tape recording division, which reduced its scope to data recording.
Ericsson Television, formerly Tandberg Television, is a company providing MPEG-4 AVC, MPEG-2 and HEVC encoding decoding and control solutions, plus stream processing, packaging, network adaption and related products, for Contribution & Distribution (C+D), IPTV, Cable, DTT, Satellite DTH and OTT.
GlassBridge Enterprises, Inc., formerly Imation Corporation, is an American holding company. Through its subsidiary, Glassbridge focuses primarily on investment and asset management. Prior to the name change, Glassbridge had three core elements: traditional storage, secure and scalable storage and what the company calls "audio and video information" products.
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.
Quarter inch cartridge tape is a magnetic tape data storage format introduced by 3M in 1972, with derivatives still in use as of 2016. QIC comes in a rugged enclosed package of aluminum and plastic that holds two tape reels driven by a single belt in direct contact with the tape. The tape was originally 1⁄4 inch (6.35 mm) wide and anywhere from 300 to 1,500 feet long. Data is written linearly along the length of the tape in one track, or written "serpentine", one track at a time, the drive reversing direction at the end of the tape, and each track's data written in the opposite direction to its neighbor. Since its introduction, it has been widely used, and many variations exist. There is a QIC trade association that publishes QIC standards which include interfaces and logical formats. To a very large extent it was the efficiency and openness of this organization which encouraged hardware and software developers to use this type of drive and media.
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.
Travan is an 8 mm magnetic tape cartridge design developed by the 3M company, used for the storage of data in computer backups and mass storage. Over time, subsequent versions of Travan cartridges and drives have been developed that provide greater data capacity, while retaining the standard 8 mm width and 750' length. Travan is standardized under the QIC body. HP Colorado, Iomega DittoMax and AIWA Bolt are proprietary versions of the Travan format.
Density is a measure of the quantity of information bits that can be stored on a given length of track, area of surface, or in a given volume of a computer storage medium. Generally, higher density is more desirable, for it allows more data to be stored in the same physical space. Density therefore has a direct relationship to storage capacity of a given medium. Density also generally affects the performance within a particular medium, as well as price.
Exabyte Corporation was a manufacturer of magnetic tape data storage products headquartered in Boulder, Colorado, United States. Exabyte Corp. is now defunct, but the company's technology is sold by Tandberg Data under both brand names. Prior to the 2006 demise, Exabyte offered tape storage and automation solutions for servers, workstations, LANs and SANs. Exabyte is best known for introducing the Data8 (8 mm) magnetic tape format in 1987. At the time of its demise, Exabyte manufactured VXA and LTO based products. The company controlled VXA technology but did not play a large role in the LTO community.
PGS is a technologically focused oilfield service company involved in providing geophysical services worldwide. Its seismic service offerings help oil companies find oil and gas reserves offshore. Product offerings span from survey planning and data acquisition, through advanced imaging, to reservoir analysis and interpretation.
Storebrand is a financial services company in Norway. By volume, the company's main activities are related to life insurance and pension savings. However, the company also has major divisions working on investments, banking and, until 1999 and again since 2006, P&C insurance products. Through its acquisition of Swedish SPP from Handelsbanken in 2007, Storebrand gained a sizable division dedicated to the Swedish market for life insurance.
Tandberg is a surname and name of several companies:
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.
The IBM Storage product portfolio includes disk, flash, tape, NAS storage products, storage software and services. IBM's approach is to focus on data management.
Rexon Business Machines, later Rexon, Inc., was a manufacturer of small business computer systems founded by Ben C. Wang in 1978 in Culver City, California. It also became a major manufacturer of tape drives and related products. At its height, it played a significant role in the development and sale of magnetic tape data storage products. It traded on the NASDAQ under the symbol REXN until it filed for bankruptcy in 1995 and was acquired by Legacy Storage Systems, a Canadian company. It was last headquartered in Longmont, Colorado.
Spectra Logic Corporation is a computer data storage company based in Boulder, Colorado in the United States. The company builds backup and archive technology for secondary storage to protect data after it migrates from primary disk. Spectra Logic's primary product is tape libraries. The company was founded in 1979, and is a privately held company.
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.
Norsk Data (ND) was a Norwegian manufacturer of minicomputers which operated between 1967 and 1992. The company was established as A/S Nordata – Norsk Data-Elektronikk on 7 July 1967 and took into use the Norsk Data brand in 1975. The company was founded by Lars Monrad-Krohn, Rolf Skår and Per Bjørge, three computer engineers working at the Norwegian Defence Research Establishment which had just built the minicomputer SAM 2. ND's first contract was the delivery of a Nord-1 computer to Norcontrol. Initially in competition with Kongsberg, ND started delivering computers to Norwegian institutions. By 1972 the company had developed Sintran operating system, the 32-bit Nord-5 and a time sharing system.
