SuperDisk
The SuperDisk LS-120 is a high-speed, high-capacity alternative to the 90 mm (3.5 in), 1.44 MB floppy disk. The SuperDisk hardware was created by 3M's storage products group Imation in 1997, with manufacturing chiefly by Matsushita. The SuperDisk had little success in North America; with Compaq, Gateway and Dell being three of only a few OEMs who supported it. It was more successful in Asia and Australia, where the second-generation SuperDisk LS-240 drive and disk was released. 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. Iomega orphaned the project around the time they decided to release the Zip drive in 1994. The idea eventually ended up at 3M, where the concept was refined and the design ...

Floppy Disk
A floppy disk or floppy diskette (casually referred to as a floppy, or a diskette) is an obsolescent 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. 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, had a disk diameter of . Subsequently, the 5¼-inch and then the 3½-inch 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 to non-existent. Some individuals and organizations continue to use older equipment to read or transfer data from floppy disks.

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. Technical aspects The technology involves reading and writing data magnetically, while optically aligning the read/write head in the drive using grooves in the disk being sensed by an infrared LED and sensor (a form of visual servo). The magnetic head touches the recording surface, as it does in a norm ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Digital Camera
A digital camera is a camera that captures photographs in digital memory. Most cameras produced today are digital, largely replacing those that capture images on photographic film. Digital cameras are now widely incorporated into mobile devices like smartphones with the same or more capabilities and features of dedicated cameras (which are still available). 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 lens with a variable diaphragm to focus light onto an image pickup device. The diaphragm and 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 after being recorded, and store and delete images from memory. Many digital cameras can ...

Zip Drive
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 th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Super Disc
The Super NES CD-ROM System (commonly shortened as the SNES-CD), known as Super Famicom CD-ROM Adapter in Japan, is an unreleased video game peripheral for the Super Nintendo Entertainment System (SNES). The add-on built upon the functionality of the cartridge-based SNES by adding support for a CD-ROM-based format known as Super Disc. The SNES-CD platform was developed in a joint venture between Nintendo and Sony. The platform was planned to be launched as an add-on for the standard SNES, as well as a hybrid console by Sony called the PlayStation (nicknamed the "Nintendo PlayStation" to distinguish it from the later Sony console of the same name) similar to Sharp's Twin Famicom and NEC's TurboDuo. Another partnership with Philips yielded a few Nintendo-themed games for the CD-i platform instead of the SNES-CD. Sony independently furthered its developments into their own stand-alone console, which ended up inheriting the PlayStation name and would serve as the chief competitor o ...

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 International, 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 port, parallel interface and the custom Commodore Serial port, serial interface. Therefore, they can be connected to any Commodore 8-bit system, from the Commodore PET to the Commodore 64, C64 and Commodore 128, 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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cylinder-Head-Sector
Cylinder-head-sector (CHS) is an early method for giving addresses to each physical block of data on a hard disk drive. It is a 3D-coordinate system made out of a vertical coordinate ''head'', a horizontal (or radial) coordinate ''cylinder'', and an angular coordinate ''sector''. Head selects a circular surface: a platter in the disk (and one of its two sides). Cylinder is a cylindrical intersection through the stack of platters in a disk, centered around the disk's spindle. Combined, cylinder and head intersect to a circular line, or more precisely: a circular strip of physical data blocks called ''track''. Sector finally selects which data block in this track is to be addressed, as the track is subdivided into several equally-sized portions, each of which is an arc of (360/n) degrees, where n is the number of sectors in the track. CHS addresses were exposed, instead of simple linear addresses (going from ''0'' to the ''total block count on disk - 1''), because early hard drive ...

FAT16B
File Allocation Table (FAT) is a file system developed for personal computers. Originally developed in 1977 for use on floppy disks, it was adapted for use on hard disks and other devices. It is often supported for compatibility reasons by current operating systems for personal computers and many mobile devices and embedded systems, allowing interchange of data between disparate systems. The increase in disk drives capacity required three major variants: FAT12, FAT16 and FAT32. The FAT standard has also been expanded in other ways while generally preserving backward compatibility with existing software. FAT is no longer the default file system for Microsoft Windows computers. FAT file systems are still commonly found on floppy disks, flash and other solid-state memory cards and modules (including USB flash drives), as well as many portable and embedded devices. FAT is the standard file system for digital cameras per the DCF specification. Overview Concepts ... [...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] |
