The SMD family became the predominant disk drive in the minicomputer market into the 1980s. Also in 1973, IBM introduced the IBM 3340 "Winchester" disk drive and the 3348 data module, the first significant commercial use of low mass and low load heads with lubricated platters and the last IBM disk drive with removable media. This technology and ...

The IBM 1311 Disk Storage Drive was announced on October 11, 1962, and was designed for use with several medium-scale business and scientific computers. [32]
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.
Disk storage (also sometimes called drive storage) is a data storage mechanism based on a rotating disk. The recording employs various electronic, magnetic, optical, or mechanical changes to the disk's surface layer. A disk drive is a device implementing such a storage mechanism.
It was incorporated August 6, 1979. Initially the company offered three 5 1/4" disk drives with a capacity of 5, 10 or 15 megabytes (unformatted). Early investors in the company included Intel Corporation. The company made an initial public offering on August 23, 1983 of approximately 2,000,000 shares of common stock.
It became a major player in the HDD market. It was the worldwide leader in 14-inch disk drive technology in the OEM marketplace in the late 1970s and early 1980s especially with its SMD (Storage Module Device) and CMD (Cartridge Module Drive), with its plant at Brynmawr in the South Wales valleys running 24/7 production. The Magnetic ...
A hard disk drive (HDD), hard disk, hard drive, or fixed disk [a] is an electro-mechanical data storage device that stores and retrieves digital data using magnetic storage with one or more rigid rapidly rotating platters coated with magnetic material.
