Detailed explanation-1: -IBM introduces the 350 RAMAC, the first computer disk storage system. In less than a second, the 350 RAMAC’s “random access” arm retrieves data stored on any of 50 spinning disks.
Detailed explanation-2: -The IBM 1311 Disk Storage Drive provided storage for two million characters. Debuting in 1962, the 1311 used the IBM Disk Pack–an interchangeable package containing six 14-inch-diameter disks in a four-inch stack, weighing 10 pounds.
Detailed explanation-3: -The IBM 1311 Disk Storage Drive provided storage for 2 million characters. Developers of the 1311 engineered twice the recording density of the IBM 1301 Disk Storage Unit by reducing the space between the head and the disk by about a factor of two.
Detailed explanation-4: -Hard Disk: Historical Significance With time, IBM continued decreasing the size of the disks and the platters. For instance, in 1979, IBM’s 3370 used seven 14-inch platters to store 571MB, the first drive to use thin-film heads.
