Popis:	In an Information machine system's dynamics gets affected by the attached information reservoir. Second law of thermodynamics can be apparently violated for this case. In this article we have derived second law for an information machine, when the system is connected to multiple heat baths along with a work source and a single information reservoir. Here a sequence of bits written on a tape is considered as an information reservoir. We find that the bath entropy production during a time interval is restricted by the change of Shannon entropy of the composite system (system + information reservoir) during that interval. We have also given several examples where this law can be applicable and shown that our bound is tighter. Comment: 14 pages, 3 figure
