SuperDisk
The SuperDisk LS-120 is a high-speed, high-capacity alternative to the 90 mm (3.5 in), 1.44 Megabyte, MB floppy disk. The SuperDisk hardware was created by 3M's storage products group Imation in 1996, with manufacturing chiefly by Panasonic, Matsushita. The SuperDisk had little success in North America; with Compaq, Gateway, Inc., Gateway and Dell being three of only a few Original equipment manufacturer, OEMs who supported it. It was more successful in Asia and Australia, where the majority of second-generation SuperDisk LS-240 drives and disks were released. There was one model of LS-240 drive released in North America, by QPS. SuperDisk worldwide ceased manufacturing in 2003. History The design of the SuperDisk system came from an early 1990s project at Iomega. It is one of the last examples of floptical technology, where lasers are used to guide a magnetic head which is much smaller than those used in traditional floppy disk drives.

Floppy Disk
A floppy disk or floppy diskette (casually referred to as a floppy, a diskette, or a disk) is a type of disk storage composed of a thin and flexible disk of a magnetic storage medium in a square or nearly square plastic enclosure lined with a fabric that removes dust particles from the spinning disk. The three most popular (and commercially available) floppy disks are the 8-inch, 5¼-inch, and 3½-inch floppy disks. Floppy disks store digital data which can be read and written when the disk is inserted into a floppy disk drive (FDD) connected to or inside a computer or other device. The first floppy disks, invented and made by IBM in 1971, had a disk diameter of . Subsequently, the 5¼-inch (133.35 mm) and then the 3½-inch (88.9 mm) became a ubiquitous form of data storage and transfer into the first years of the 21st century. 3½-inch floppy disks can still be used with an external USB floppy disk drive. USB drives for 5¼-inch, 8-inch, and other-size floppy disks are rare ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Floptical
Floptical refers to a type of floppy disk drive that combines magnetic and optical technologies to store data on media similar to standard -inch floppy disks. The name is a portmanteau of the words "floppy" and "optical". It refers specifically to one brand of drive and disk system, but is also used more generically to refer to any system using similar techniques. The original Floptical technology was announced in 1988 and introduced late in 1991 by Insite Peripherals, a venture funded company set up by Jim Adkisson, one of the key engineers behind the original -inch floppy disk drive development at Shugart Associates in 1976. The main shareholders were Maxell, Iomega and 3M. This original format normally held 21 MB of data, compared to the contemporary 3.5" floppy capacity of 720 kB or 1.44 MB. Over the next several years, similar products were introduced by other companies with ever increasing capacity, eventually reaching 240 MB in some systems. All of ...

Zip Drive
The Zip drive is a removable floppy disk storage system that was announced by Iomega in 1994 and began shipping in March 1995. Considered medium-to-high-capacity at the time of its release, Zip disks were originally launched with capacities of 100 megabytes, MB, then 250 MB, and finally 750 MB. The format became the most popular of the superfloppy products which filled a Niche market, niche in the late 1990s portable storage market. However, it was never popular enough to replace the standard -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 standard -inch floppy drive's convenience, but with much greater capacity options and with performance that is much improved over a s ...

SuperDrive
SuperDrive is the product name for a floppy disk drive and later an optical disc drive made and marketed by Apple Inc. The name was initially used for what Apple called their high-density floppy disk drive, and later for the internal CD and DVD drive integrated with Apple computers. Though Apple no longer manufactures computers that feature built-in SuperDrives, the name is still used when referring to Apple's external CD and DVD drive accessory (pictured). Floppy disk drive The term was first used by Apple Computer in 1988 to refer to their 1.44 MB 3.5 inch floppy drive. This replaced the older 800 KB floppy drive that had been standard in the Macintosh up to then, but remained compatible in that it could continue to read and write both 800 KB (double-sided) and 400 KB (single-sided) floppy disks, as well as the newer high-density floppies. This drive was also capable of reading and writing MS-DOS formatted disks and FAT12 file formats, using PC E ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Digital Camera
A digital camera, also called a digicam, is a camera that captures photographs in Digital data storage, digital memory. Most cameras produced today are digital, largely replacing those that capture images on photographic film or film stock. Digital cameras are now widely incorporated into mobile devices like smartphones with the same or more capabilities and features of dedicated cameras. High-end, high-definition dedicated cameras are still commonly used by professionals and those who desire to take higher-quality photographs. Digital and digital movie cameras share an optical system, typically using a Camera lens, lens with a variable Diaphragm (optics), diaphragm to focus light onto an image pickup device. The diaphragm and Shutter (photography), shutter admit a controlled amount of light to the image, just as with film, but the image pickup device is electronic rather than chemical. However, unlike film cameras, digital cameras can display images on a screen immediately afte ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Super Disc
The Super NES CD-ROM (commonly abbreviated as SNES CD) was a series of unreleased devices developed in the early 1990s that would have added CD-ROM capabilities to the Super Nintendo Entertainment System. The project was conceived as an add-on device for the Super NES as well as a dedicated all-in-one unit, all of which would support playback of CDs. Games would also be stored on the medium, using two distinct formats based on CD-ROM. Nintendo collaborated with Sony to develop the project, which led to the development of an all-in-one unit known as the PlayStation that was capable of playing both Super NES cartridges and a new CD-based format named the ''Super Disc''. The two companies worked on the project until Nintendo collaborated with Sony's competitor, Philips, to work on the project as well, with that particular partnership leading to the development of an add-on for the Super NES that can accept CDs and used a different format for storing games on a CD-ROM. Ultimately, bot ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
MSD Super Disk
The MSD Super Disk were a series of 5¼-inch floppy disk drives compatible to some degree with the Commodore 1541 disk drive. produced by Micro Systems Development (Dallas, Texas; later MSD Systems) for use with Commodore 8-bit home computers. Two different versions of the MSD Super Disk were available: the single-drive model, SD-1; and the dual-drive model, SD-2. Introduction Introduced in 1983, the MSD Super Disk drives were the first third-party devices designed for compatibility with the Commodore 64, although other manufacturers soon followed suit. The MSD drives include both an IEEE-488 parallel interface and the custom Commodore serial interface. Therefore, they can be connected to any Commodore 8-bit system, from the Commodore PET to the C64 and C128, without any converters or other add-on devices. Features and pricing The MSD SD-1 was more expensive than the Commodore 1541. For instance, a typical mail-order advertisement in the January 1985 issue of '' RUN'' Magazine ...

Superformatting
Superformatting is the process of formatting a floppy disk at a capacity that the disk is not designed for. It can ruin a floppy disk, but it is used in some floppy-based Linux distros to increase the room for applications and utilities. muLinux is a notable example of this technique. Another common use (which is not as popular nowadays) was to format low-density 3.5-inch or 5.25-inch floppies as high-density, or in the case of 3.5-inch disks, even extra-high density (HD-36). "Notched" disks will usually turn up a lot of bad sectors, especially if the formatted capacity is a considerable (1.5 to 3) number of times higher than intended. Superformatting is usually done with a low-level format (such as "FORMAT /U" in DOS DOS (, ) is a family of disk-based operating systems for IBM PC compatible computers. The DOS family primarily consists of IBM PC DOS and a rebranded version, Microsoft's MS-DOS, both of which were introduced in 1981. Later compatible syste ... and " fdfor ...

WinHelp
Microsoft WinHelp is a proprietary format for online help files that can be displayed by the Microsoft Help browser ''winhelp.exe'' or ''winhlp32.exe''. The file format is based on Rich Text Format (RTF). It remained a popular Help platform from Windows 3.0 through Windows XP. WinHelp was removed in Windows Vista purportedly to discourage software developers from using the obsolete format and encourage use of newer help formats. Support for WinHelp files would eventually be removed entirely in Windows 10. History * 1990 – WinHelp 1.0 shipped with Windows 3.0. * 1995 – WinHelp 4.0 shipped with Windows 95 / Windows NT. * 2006 – Microsoft announced its intentions to phase out WinHelp as a supported platform. WinHelp is not part of Windows Vista out of the box. WinHelp files come in 16 bit and 32 bit types. Vista treats these files types differently. When starting an application that uses the 32 bit .hlp format, Windows warns that the format is no longer supported. A download ...
