The 'rotating-disk method' of Mingotaud et al. (C. Mingotaud, B. Agricole, C. Jego, J. Phys. C-hem. 99 (1995) 17068) is a powerful technique for obtaining Langmuir-Blodgett films with controlled in-plane organization. In this report we compare the two versions of this method with, respectively, one-disk and two-disk systems. The one-disk version consists of a simpler mechanical system and highly efficient for macroscopically homogeneous monolayers having adequate visco-elastic properties. For some inhomogeneus monolayers, however, the two-disk version is more effective to induce the in-plane organization.
