The tearing mode in multiple periodic current sheet systems with a hyperbolic tangent profile of magnetic shear has been investigated. It is found that the linear growth rate of the antisymmetric and symmetric mode tearing instability increases and decreases, respectively, with the current sheet separation decreasing, which is similar to the situation with the step function profile of current density [A. Otto and G. T. Birk, Phys Fluids B 4, 3811 (1992)]. But, the results here also show that the linear growth rate of the antisymmetric mode tearing instability maximizes at certain current sheet separation. The linear growth of the tearing instability in multiple current sheet systems is not enhanced as greatly as has usually been expected. © 1998 American Institute of Physics.
