13 janv. 1956 - RAMAC Disk Drive
Description:
The era of magnetic disk storage dawns with IBM´s shipment of a RAMAC 305 computer system to Zellerbach Paper in San Francisco. The computer was based on the new technology of the hard disk drive — the world’s first. The RAMAC disk drive consisted of 50 magnetically coated metal platters capable of storing about 5 million characters of data. RAMAC allowed real-time random access to large amounts of data, unlike magnetic tape or punched cards. A working RAMAC hard disk assembly is demonstrated regularly at the Computer History Museum.
