This invention provides an extremely high throughput magnetic disk drive which uses massively parallel architecture to achieve unprecedented sequential and random access transfer rates. The drive consists of a stationary magnetic head assembly (20) comprising a single integrated circuit (21) made of silicon along with the associated disk (24) and controller (81). This integrated circuit contains heads (22), amplifiers, buffers and circuits for verification of all disk operations. The head assembly operates on disks made of crystalline silicon to avoid problems of differential thermal contraction and to insure rigidity. It communicates with the host computer's random access memory by means of a novel and unique disk controller, which has the high capacity throughput to take advantage of the high throughput speed of this disk drive. The most important feature of this disk drive is that all disk tracks are processed (read or written) concurrently each time a given sector is available to the heads, which means that the entire disk can be read or written on each revolution. |
