Collectable piece of history from the beginning of the computing age. The read write heads in early disk drive were replaced manually as needed. As apparent this one must have been involved in a head \'crash\' judging from the scarring.
Announced one year after the System/360 in April 1965, the IBM 2314 provided eight disk drives and a spare along with a control unit together in one facility. A new disk pack with 11 disks doubled the number of storage surfaces over those available in the first removable disk pack. Increased recording density provided a storage capacity of 29.2 million bytes per pack or 233 million bytes in the eight-pack facility. The access time and latency of the 2314 was the same as the older IBM 2311 but the 2314 offered double the data rate of 310,000 bytes per second. The 2314 also was attractive because it was four times lower in price per megabyte of storage.
Aided by OS/360 -- the System/360\'s operating system -- the 2314 allowed large databases to be accessed, and the system shifted from job to job automatically as long as the necessary instructions and data were online. Some observers have said that OS/360 helped to make the 2314 the most profitable storage product to that time and that the 2314 contributed to the success of the System/360.
