Abstract
This Comment suggests a different interpretation for magnetoabsorption resonances in Bi compounds in magnetic fields very close to the ab plane observed by Matsuda et al. The observed resonances are related with the Josephson-vortex oscillating mode governed by weak pinning of pancakes, but not with the Josephson-plasma mode as was suggested by Matsuda et al.
