Oribital dynamics of the spatially homogeneous superfluid /sup 3/He-A is investigated microscopically within the framework of a matrix kinetic equation which includes the correct collision term. Leggett and Takagi's phenomenological theory is justified near the transition temperature when ..omega../..delta..very-much-less-than1,tau..delta..>>1. The microscopic origin of the different dynamical properties of orbital dynamics from those of spin dynamics as well as of isotropic two-fluid dynamics is considered in detail. It is shown that in the orbital dynamics of the ABM state there is no local equilibrium situation, where the configuration of the Bogoliubov quasiparticles follows a temporal rotation of the l vector. As a result, the intrinsic angular momemtum cofficient L/sub 0/ has the collisionless-limit from even in the low-frequency limit.
