Drawings from IBM Floppy Disk Drive Patents. IBM's decision in the late 1960s to use semiconductor memory as the writeable control store for future systems and control units created a requirement for an inexpensive and reliable read only device and associated medium to store and ship the control store's microprogram and at system power on to load the microprogram into the control store.
However, what Nakamatsu patented in 1952 was a paper for optical sound player. [12] In contrast to a floppy disk, this Nakamatsu patent discloses the use of printed paper for storage instead of the magnetic material of a floppy disk. It is not rewritable and lacks most elements of the IBM floppy disk patent.
8-inch floppy disk, inserted in drive, (3½-inch floppy diskette, in front, shown for scale) 3½-inch, high-density floppy diskettes with adhesive labels affixed The first commercial floppy disks, developed in the late 1960s, were 8 inches (203.2 mm) in diameter; [4] [5] they became commercially available in 1971 as a component of IBM products and both drives and disks were then sold ...
Paper data storage refers to the use of paper as a data storage device. This includes writing, illustrating, and the use of data that can be interpreted by a machine or is the result of the functioning of a machine. A defining feature of paper data storage is the ability of humans to produce it with only simple tools and interpret it visually.
However, by the late 1980s, hard disk drives were standard on all but the cheapest PC and floppy disks were used almost solely as transport media. Most hard disk drives in the early 1980s were sold to PC end users by systems integrators such as the Corvus Disk System or the systems manufacturer such as the Apple ProFile.
regular people started to use computers – and wanted a simple way to run a program; computer magazines started to include cassette tapes or floppy discs with free or trial versions of software on them; Very quickly, commercial software started to be pirated, and commercial software producers were very unhappy at this.
The Olivetti P6060 was the first personal computer with a built-in floppy disk. It was presented in April 1975 by the Italian manufacturer Olivetti at the Hannover fair alongside the smaller P6040 that stored data on proprietary 2.5-inch mylar floppies called Minidisk (3 KB).
A Maxell-branded 3-inch Compact Floppy Disk. The floppy disk is a data storage and transfer medium that was ubiquitous from the mid-1970s well into the 2000s. [1] Besides the 3½-inch and 5¼-inch formats used in IBM PC compatible systems, or the 8-inch format that preceded them, many proprietary floppy disk formats were developed, either using a different disk design or special layout and ...
