Z, Supposedly anything over about 30,000 tracks per inch requires microactuation, which Hutchinson has patented. What do you know about these patents? Is this a new technology that HTCH patented or is it an existing technology that HTCH patented for the use in disk drive suspensions? Sounds great as a HTCH shareholder but I have to be a bit skeptical that they could lock this up with patents. I'd sure like to know more. -Robert

Z, re >Supposedly anything over about 30,000 tracks per inch requires microactuation, which Hutchinson has patented< They have a patent on a microactuation process? I can't believe they patented microactuation as a method. Gottfried

<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. Regards, Mark
