Open the CIPO recordAbstract From the Canadian patent
An improved magnetic head suspension having a unitary load beam (10) and flexure structure with a gimballed slider baseplate (12) etched into the slider. The present magnetic head suspension assembly overcomes prior art limitations by making the load beam (10) and flexure from one piece of sheet material. Thus the accuracy, of orientation of the flexure in relation to the load beam (10) is carefully controlled and the overall structure can be optimized to improve its dynamic characteristics and greatly reduce its size.

Why it's free to use
- Filed November 8, 1991. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended November 8, 2011.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by November 8, 2013.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
