从第一块硬盘RAMAC的产生到现在单碟容量高达15GB多的硬盘,硬盘也经历了几代的发展,下面就介绍一下其历史及发展。 1956年9月,IBM的一个工程小组向世界展示了第一台磁盘存储系统IBM 350 RAMAC(Random Access Method of Accounting and Control),其磁头可以直接移动到盘片上的任何一块存储区域,从而成功地实现了随机存储,这套系统的总容量只有5MB,共使用了50个直径为24英寸的磁盘,这些盘片表面涂有一层磁性物质,它们被叠起来固定在一起,绕着同一
From the first hard disk RAMAC generation to the current single platter capacity of up to 15GB more hard drives, hard drives have gone through several generations of development, the following describes its history and development. In September 1956, a team of IBM engineers showed the world the first Random Access Method of Accounting and Control (RAMAC) disk with a head that moved directly to any storage area on the disk to successfully Achieved random storage, the total capacity of this system is only 5MB, the total use of 50 24-inch diameter disk, the disk coated with a layer of magnetic material, which are stacked together to fix together around the same
