winchester disk was introduced in

The term for hard disk drive. The 3340 offered the optional availability of fixed heads, which provided an average access time of only five milliseconds. In 1970, IBM introduced the 2305 disk drive, with a head per track. IBM's Winchester disk was a removable cartridge, but the heads and platters were built in a sealed unit and were not separable. Since that first disk drive, technological advances have been made at an astonishing rate, with data capacity increasing and size and price decreasing exponentially, year on year. Turn of the millennium A floppy disk or floppy diskette (sometimes casually referred to as a floppy or diskette) 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. In the middle of 1970s, a 5.25 diskette was introduced. In 1961, it invented drive heads in the form of airfoils that hovered just above the surface of the disks, which is the standard for today. Winchester Disk. Although modern disk drives are faster and hold more data, the basic technology is the same, so Winchester has become synonymous with hard. Alternatives such as Zip disks (discussed later), or transferring data via networks are making the low-capacity diskette become obsolete. In 1961, the IBM 1301 Disk Storage Unit was released, which utilized heads that floated on a thin layer of air.
