History Of The Floppy Disk
A floppy disk is a disk storage medium composed of a disk of thin and flexible magnetic storage medium encased in a rectangular plastic carrier. It is read and written using a floppy disk drive (FDD). Floppy disks were an almost universal data format from the 1970s into the 1990s, used for primary data storage as well as for backup and data transfers between computers. In 1967, at an IBM facility in San Jose (CA), work began on a drive that led to the world's first floppy disk and disk drive. It was introduced into the market in an format in 1971. The more conveniently sized 5¼-inch disks were introduced in 1976, and became almost universal on dedicated word processing systems and personal computers. This format was more slowly replaced by the 3½-inch format, first introduced in 1982. There was a significant period where both were popular. A number of other variant sizes were introduced over time, with limited market success. Floppy disks remained a popular medium for nearly ...

Floppy Disk 2009 G1
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.

Form Factor (design)
Form factor is a hardware design aspect that defines and prescribes the size, shape, and other physical specifications of components, particularly in electronics. A form factor may represent a broad class of similarly sized components, or it may prescribe a specific standard. It may also define an entire system, as in a computer form factor. Evolution and standardization As electronic hardware has become smaller following Moore's law and related patterns, ever-smaller form factors have become feasible. Specific technological advances, such as PCI Express, have had a significant design impact, though form factors have historically been slower to evolve than individual components. Standardization of form factors is vital for compatibility of hardware from different manufacturers. Trade-offs Smaller form factors may offer more efficient use of limited space, greater flexibility in the placement of components within a larger assembly, reduced use of material, and greater ease of tran ...

Shugart Associates
Shugart Associates (later Shugart Corporation) was a computer peripheral manufacturer that dominated the floppy disk drive market in the late 1970s and is famous for introducing the -inch "Minifloppy" floppy disk drive. In 1979 it was one of the first companies to introduce a hard disk drive form factor compatible with a floppy disk drive, the SA1000 form factor compatible with the 8-inch floppy drive form factor. Founded in 1973, Shugart Associates was purchased in 1977 by Xerox, which then exited the business in 1985 and 1986, selling the brand name and the 8-inch floppy product line (in March 1986) to Narlinger Group, which ultimately ceased operations circa 1991. History Beginnings Alan Shugart, after a distinguished career at IBM and a few years at Memorex, decided to strike out on his own in 1973; after gathering venture capital, he started Shugart Associates. The original business plan was to build a small-business system (similar to the IBM 3740) dealing with the developm ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Punched Card
A punched card (also punch card or punched-card) is a piece of stiff paper that holds digital data represented by the presence or absence of holes in predefined positions. Punched cards were once common in data processing applications or to directly control automated machinery. Punched cards were widely used through much of the 20th century in the data processing industry, where specialized and increasingly complex unit record equipment, unit record machines, organized into semiautomatic data processing systems, used punched cards for data input, output, and storage. The IBM 12-row/80-column punched card format came to dominate the industry. Many early digital computers used punched cards as the primary medium for input of both computer programs and Data (computing), data. While punched cards are now obsolete as a storage medium, as of 2012, some voting machines still used punched cards to record votes. They also had a significant cultural impact.

Mohawk Data Sciences Corporation
Mohawk Data Sciences Corporation (MDS) was an early computer hardware company, started by former Univac engineers in 1964; by 1985 they were struggling to sell-off part of their company. History The company was founded in Herkimer, New York, by George Cogar, Lauren King, and Ted Robinson, former Univac employees. Their success in selling their first product, a Key-to-Tape Data Entry device that allowed doing away with Keypunch devices, brought them enough cash to also grow via acquisition. Among their acquisitions was Atron Corporation, developer of a minicomputer, the Atron 501 and 502. From the know-how acquired and absorbed, Mohawk expanded into the areas of controlling line printers and also Remote Job Entry (RJE). This was the basis of their MDS 2400 RJE product, which supported 2780 and HASP. Financial difficulties a decade-and-a-half after the company opened led to the company's restructuring, renaming and eventual takeover. By that time, headquarters had been in Pa ...
