(1) In Table 2, the parameter values should be changed as follows:M=1.918mg (effective mass including suspension is 1.25 times the slider mass (1.59 mg)).J=2.971×1013kgm2 (effective moment of inertia including suspension is 1.36 times that of the slider only (2.19×1013kgm2)).The mass and moment of inertia of the slider are important parameters for determining the slider instability. If the mass and moment of inertia listed in Table 2 are used, the slider does not become unstable.

(2) The air-bearing damping coefficients, described on p. 70, in the right-hand column, line 10, are determined not by cf=2ζfMkf0 and cr=2ζrMkr0 but by cf=2ζfMkf and cr=2ζrMkr.

(3) In the caption of Fig. 7, r=2.4 should be replaced with r=2.6, as described in the text. However, the difference between the calculated results for r=2.4 and r=2.6 is very small.

We would like to thank Professor D. B. Bogy for bringing these errors to our attention.
