<A silver lining in IBM's areal density announcement was that the record was acheived at a track density of 67,300 tracks per inch. Supposedly anything over about 30,000 tracks per inch requires microactuation, which Hutchinson has patented. >

The eventual need for microactuation is probably sure, but for these tests, it has always been my understanding that they are based on a single disk on a spin stand with a suspension that does not move across tracks, but just writes to a single track. That's why it takes so long to bring these great densities to market.
