Open the CIPO recordAbstract From the Canadian patent
The 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 comprising a single integrated circuit made of silicon along with the associated disk and controller. This integrated circuit contains heads 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 …

Why it's free to use
- Filed June 22, 2001. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended June 22, 2021.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by June 22, 2023.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
