Each hard drive plater is divided . The rest of the operating system was basically a command monitor. al. 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. Today, recordable CDs/DVDs, flash drives and cloud drives have since replaced floppies as the primary means of transporting files from one computer to another computer. Here are a few highlights from the early years: Winchester entered the shotshell market in 1886 with Rival brand ammo in 10, 12, 14, 16 and 20 gauge.

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 smaller media generally conformed to de facto standard form factors. In 1961 IBM introduced the model 1311 disk drive, which was about the size of a washing machine and stored two million characters on a removable disk "pack." . The structure of the software evolved from Gary Hornbuckle's 1968 paper "Multiprocessing Monitor for Small Machines" and from PDP8-based systems I worked on at Berkeley Scientific Laboratories (BSL) in the late 1960s. .
