"Classic" hard drives: controllers, cabinets, disks, docs & hints * Some observers have noted that the 3340 was known as "Winchester" because its development engineers called it a "30-30" (its two spindles each had a disk capacity of 30 megabytes), the common name of a rifle manufactured by the Winchester Company. Derived from the original specification of a system having two spindles each with a disk capacity of 30 MB, Haughton is reported to have said: "If it's a 30-30, then it must be a Winchester" after the .30-30 Winchester rifle cartridge.

Eventually that term fell out of favor for the easier to type "Hard Disk." The Winchester name came directly from the famous rifle, as IBM announced a 30 Meg removable over a 30 Meg sealed disk (presumably for backups) and called it a "30-30."

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. Drives with the larger 24-inch- and 14-inch-diameter media were typically mounted in standalone boxes (resembling washing machines) or large equipment rack enclosures. your Winchester disk if those that are preset do not meet your needs.

The IBM3340 hard disk drive (HDD) that began shipping in November 1973 pioneered new low-cost, low-load, landing read/write heads with lubricated disks, and established what became the dominant HDD technology. In 1890 they introduced the .22 Winchester Rimfire cartridge (now obsolete). It demonstrated a significant advance in technology, allowing an increase in recording density to 300 tracks per inch and 5600 bits per inch. It does not store any personal data. (See Manufacturing history for more details), In 2009 Fujitsu exits by selling HDD business to Toshiba[20], In 2011 Floods hit many hard drive factories. The work at BSL was largely inspired by the late Rudolph Langer, who improved significantly on Hornbuckle's model. Advertise with TechnologyAdvice on Webopedia and our other IT-focused platforms. We used floppy disks and cassettes mostly as paper tape replacements, but we also appreciated and exploited the random access nature of disks. Drives with smaller media generally conformed to de facto standard form factors.
IBM Archives: IBM 3340 direct access storage facility The 3340 featured a smaller, lighter read/write head that could ride closer to the disk surface -- on an air .
In the 1980s 8-inch drives used with some mid-range systems increased from a low of about 30MB in 1980, to a top-of-the-line 3GB in 1989.[17].
