There is overwhelming evidence supporting the existence of the Dark Matter (DM),
however still relatively little is known about its nature. In particular, it is
most likely that the DM is not strongly self interacting and cold. Also
stringent bounds have been put on the strength of the interaction between the
dark and baryonic matter. I will briefly review these results and the
experimental evidence that supports them. I will further advocate a scenario of
multi-component DM, such that one of these components has a non-trivial
dissipative dynamics. In this case the dissipative component might collapse
into a "dark galactic disk" similar to the baryonic matter, which
collapses into a baryonic disk. I will elaborate on experimental consequences
of this scenario and overview the observations that might either confirm or
reject the dark disk hypothesis in the near future.
