FYI HTCH/ROG Excerpt from the Rogers press release... <<TOKYO, Oct. 6 /PRNewswire/ -- Yesterday in Tokyo, two company presidents signed an agreement that creates a new specialty circuit material company, Polyimide Laminate Systems (PLS). The new company is a 50-50% joint venture between Mitsui Chemicals, Inc. of Tokyo, Japan, and Rogers Corporation (Amex: ROG - news) of Rogers, Connecticut, U.S.A. PLS will manufacture a specialty flexible circuit board laminate used for making the read/write head suspension assemblies in high performance, hard disk drives (HDD's). These suspension assemblies, produced by Hutchinson Technology, Inc., (Nasdaq: HTCH - news) of Hutchinson, Minnesota, for advanced HDD's, are the technology of choice in new HDD designs. Called TSA(TM) Trace Suspension Assemblies, this Hutchinson product allows manufacturers to lower costs and improve performance. Hutchinson, the world's leading supplier of suspension assemblies for HDD's, has led the advancement of drive technology since entering the business in 1982.>>

Z, yes - as track densities increased the radial tolerances decreased proportionately. The head can probably be offtrack a little more than 10% of track width before reading the data becomes impossible because of too many errors. [in spite of improved error correction schemes] So, any track width decrease requires improvement in mechanical tolerances. Also, there are nonrepeatable components to the radial mechanical tolerances. These cannot be compensated by head movement. Gottfried I've been out of the biz 5 years, so may have missed something.
