What is A Winchester Disk Drive? | Webopedia Individual drives often required high-current AC power due to the large motors required to spin the large disks. This was IBM's first drive to not unload the heads from the media. It held 5MB of data, at a cost of $10,000 per megabyte. A floppy disk is called a floppy because the original floppies were 8 inches wide and the disk was made out of vinyl so they were really flimsy and floppy hence came the name floppy. The disks also had a 30 ms access time, and lubricated coating allowing the heads to remain in contact with the surface when rotation speed changes. Mateosian is currently a review editor at IEEE Micro in Berkeley, CA. In a nutshell, a computer drive, also called a disk drive, is a device that stores digital information from your computer, sort of like keeping beans in a jar. Smaller diameter media came into usage during the 1970s and by the end of the decade standard form factors had been established for drives using nominally 8-inch media (e.g., Shugart SA1000) and nominally 5.25-inch media (e.g., Seagate ST-506).
