Gigantic 5 MB Hard Drive

at 5:21 am. Filed under Insane Equipment

This is the first hard drive made. It is a whopping 5MB in size, funny thing is that even though drive sizes have increased tremendously the underlying technology is surprisingly similar…

“Information is stored, magnetically, on fifty disks which rotate at 1200 rpm. These disks are mounted so as to rotate about a vertical axis, with a spacing of three tenths of an inch between disks. This spacing permits two magnetic heads to be positioned to any one of the 100 concentric tracks which are available on each side of each disk. Each track contains 500 alphanumeric characters. Total storage capacity: 5,000,000 characters. The two recording heads are mounted in a pair of arms which are moved, by a feed-back control system, in a radial direction to straddle a selected disk. This new system promises memory storage possibilities never before accomplished.”
