Ditto (drive)
The Ditto drive series was a proprietary magnetic tape data storage system released by Iomega during the 1990s. It was marketed as a backup device for personal computers. They were released in several capacities ranging from the original Ditto 250 drive (250MB compressed capacity per cartridge) to the DittoMAX drive, a compatible format with compressed capacities up to 10GB per cartridge. This was accomplished by increasing the physical size of the cartridge (making it longer). Some versions of the drive were also able to read Travan-type tapes. Technical aspects Ditto internal drives were connected through the floppy drive channel and used MFM encoding to store data (the same method as on older floppy drives). An ISA accelerator card called the ''Ditto Dash'', providing higher speed than a stock floppy controller, was also available. Ditto external drives were connected to the parallel port and offered a print-through port which allowed a printer to operate while daisy-cha ...

Iomega Ditto 2GB Drive And Tape
Iomega (later LenovoEMC) produced external, portable, and networked data storage products. Established in the 1980s in Roy, Utah, United States, Iomega sold more than 410 million digital storage drives and disks, including the Zip drive floppy disk system. Formerly a public company, it was acquired by EMC Corporation in 2008, and then by Lenovo, which rebranded the product line as LenovoEMC, until discontinuation in 2018. History Iomega started in Roy, Utah, U.S. in 1980 and moved its headquarters to San Diego, California in 2001. For many years, it was a significant name in the data storage industry. Iomega's most famous product, the Zip Drive, offers relatively large amounts of storage on portable disks. The original Zip disk's 100MB capacity is a huge improvement over the decades-long standard of 1.44MB floppy disks. The Zip Drive became a common internal and external peripheral for IBM-compatible and Macintosh personal computers. However, Zip disks sometimes failed after a ...

Daisy Chain (information Technology)
In electrical and electronic engineering, a daisy chain is a wiring scheme in which multiple devices are wired together in sequence or in a ring, similar to a garland of daisy flowers. Daisy chains may be used for power, analog signals, digital data, or a combination thereof. The term ''daisy chain'' may refer either to large scale devices connected in series, such as a series of power strips plugged into each other to form a single long line of strips, or to the wiring patterns embedded inside of devices. Other examples of devices which can be used to form daisy chains are those based on Universal Serial Bus (USB), FireWire, Thunderbolt and Ethernet cables. Signal transmission For analog signals, connections usually consist of a simple electrical bus and, especially in the case of a chain of many devices, may require the use of one or more repeaters or amplifiers within the chain to counteract attenuation (the natural loss of energy in such a system). Digital signals ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tape Drive
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. A tape drive provides sequential access storage, unlike a hard disk drive, which provides direct access storage. A disk drive can move to any position on the disk in a few milliseconds, but a tape drive must physically wind tape between reels to read any one particular piece of data. As a result, tape drives have very large average access times. However, tape drives can stream data very quickly off a tape when the required position has been reached. For example, Linear Tape-Open (LTO) supports continuous data transfer rates of up to 360 MB/s, a rate comparable to hard disk drives. Design Magnetic tape drives with capacities of less than one megabyte were first used for data storage on mainframe computers in the 1950s. , capaci ...

Quarter-inch Cartridge
Quarter inch cartridge tape (abbreviated QIC, commonly pronounced "quick") 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 wide and anywhere from long. Data is written linearly along the length of the tape in one track (mostly on pre-1980 equipment), 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 an ...

Irwin Magnetics
Irwin Magnetic Systems was a computer storage manufacturer founded in 1979 and based in Ann Arbor, Michigan. At its height, the company employed 600 people in Ann Arbor. The company's primary product line was magnetic tape data storage systems, particularly the proprietary AccuTrak format. This format was widely adopted by Compaq, HP and other OEM manufacturers, and was also incorporated into IBM Personal System 2 (PS2) personal computers as an option. In 1989, the company was acquired by Cipher Data Products, which was in turn acquired by Archive Corporation Archive Corporation was a computer tape drive manufacturer, based in Costa Mesa, California, that was acquired by Conner Peripherals in 1993.

Iomega REV
REV is a removable hard disk storage system from Iomega. The small removable disks store 35, 70, or 120 gigabytes (GB) and are hard-drive technology. Like a standard hard drive, the REV system uses a flying head to read and write data to a spinning platter. The removable disks contained the platter, spindle, and motor, while the drive heads and drive controller are contained within the REV drive. The drives allow for data transfer rates of about 25 megabytes (MB) per second. The REV was available as an external desktop model with FireWire, SCSI or USB 2.0 interfaces, an internal model with SCSI, ATAPI, or SATA interfaces, or an external server model which features a cartridge autoloader and SCSI interface. Iomega also offered a 320 GB network-attached storage appliance which features a built-in REV. The drives are compatible with Macintosh, Windows, and Linux operating systems, although some only with particular models or interfaces. This product, especially the server model, was ...

Tecmar
Tecmar Inc. was an American manufacturer of personal computer enhancement products based in Solon, Ohio. The company was founded in 1974 by Martin Alpert, M.D., and Carolyn Alpert. The company's first products were computerized medical equipment; the company shortly after pivoted to data acquisition boards for the first generation of microcomputers. Popular products included the Scientific Solutions LabMaster series of boards for S-100 and Apple Computer. Scientific Solutions In 1981, at the COMDEX show, Tecmar introduced 20 expansion cards for the new IBM Personal Computer (IBM PC) announced three months earlier. Using experience in developing scientific and industrial products for Intel 8086 microcomputers, the company purchased two PCs on the first day and up to 50 employees worked on the peripherals; Tecmar's speed surprised even IBM. These products included the Scientific Solutions LabMaster, LabTender, IEEE-488, BaseBoard, TimeMaster, GraphicsMaster, memory expansion ...

Iomega ZIP
The Zip drive is a removable floppy disk storage system that was introduced by Iomega in late 1994. Considered medium-to-high-capacity at the time of its release, Zip disks were originally launched with capacities of 100 MB, then 250 MB, and finally 750 MB. The format became the most popular of the superfloppy products which filled a niche in the late 1990s portable storage market. However, it was never popular enough to replace the -inch floppy disk. Zip drives fell out of favor for mass portable storage during the early 2000s as CD-RW and USB flash drives became prevalent. The Zip brand later covered internal and external CD writers known as Zip-650 or Zip-CD, despite the dissimilar technology. Overview The Zip drive is a "superfloppy" disk drive that has all of the -inch floppy drive's convenience, but with much greater capacity options and with performance that is much improved over a standard floppy drive. However, Zip disk housings are much thicker tha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Printer (computing)
In computing, a printer is a peripheral machine which makes a persistent representation of graphics or text, usually on paper. While most output is human-readable, bar code printers are an example of an expanded use for printers. Different types of printers include 3D printers, inkjet printers, laser printers, and thermal printers. History The first computer printer designed was a mechanically driven apparatus by Charles Babbage for his difference engine in the 19th century; however, his mechanical printer design was not built until 2000. The first patented printing mechanism for applying a marking medium to a recording medium or more particularly an electrostatic inking apparatus and a method for electrostatically depositing ink on controlled areas of a receiving medium, was in 1962 by C. R. Winston, Teletype Corporation, using continuous inkjet printing. The ink was a red stamp-pad ink manufactured by Phillips Process Company of Rochester, NY under the name Clear Prin ...

Magnetic Tape Data Storage
Magnetic-tape data storage is a system for storing digital information on magnetic tape using digital recording. Tape was an important medium for primary data storage in early computers, typically using large open reels of IBM 7 track, 7-track, later 9-track tape, 9-track tape. Modern magnetic tape is most commonly packaged in cartridges and cassettes, such as the widely supported Linear Tape-Open (LTO) and IBM 3592 series. The device that performs the writing or reading of data is called a tape drive. Autoloader (data storage device), Autoloaders and tape library, tape libraries are often used to automate cartridge handling and exchange. Compatibility was important to enable transferring data. Tape data storage is now used more for system backup, data archive and data exchange. The low cost of tape has kept it viable for long-term storage and archive. Open reels Initially, magnetic tape for data storage was wound on reels. This standard for large computer systems persis ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Parallel Port
In computing, a parallel port is a type of interface found on early computers (personal and otherwise) for connecting peripherals. The name refers to the way the data is sent; parallel ports send multiple bits of data at once ( parallel communication), as opposed to serial communication, in which bits are sent one at a time. To do this, parallel ports require multiple data lines in their cables and port connectors and tend to be larger than contemporary serial ports, which only require one data line. There are many types of parallel ports, but the term has become most closely associated with the printer port or Centronics port found on most personal computers from the 1970s through the 2000s. It was an industry ''de facto'' standard for many years, and was finally standardized as IEEE 1284 in the late 1990s, which defined the Enhanced Parallel Port (EPP) and Extended Capability Port (ECP) bi-directional versions. Today, the parallel port interface is virtually non-exis ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
