Development of the Fine Axial System with Air Static Pressure in the Instrument for Testing Flying Characters of the Magnetic Discs and Heads

The instrument for testing flying characters of the magnetic discs and heads is a specialized equipment used to test the surface characters of the magnetic discs and flying characters and gaps of the heads. The fine axial system with air static pressure is the main component in it. This paper described structural design and static and dynamic characteristic expriments in detail, which proved the reasonableness of the design and the validity of the calculation by theoretical and experimental comparison. Especially the theoretical and expermental models for angle stiffness of the system was established, which provided the fundament for Lhe angle stiffness investigation.
