A gait generator determines a desired motional trajectory and a desired object reaction force trajectory of an object 120 for a predetermined period after the current time by using an object dynamic model while supplying, to the object dynamic model, a model manipulated variable (estimated disturbance force) for bringing a behavior of the object 120 on the object dynamic model close to an actual behavior, and provisionally generates a gait of a robot 1 for a predetermined period by using the aforesaid determined trajectories. Based on the gait and an object desired motion trajectory, a geometric restrictive condition, such as interference between the robot 1 and the object 120, is checked, and a moving plan for the object 120 or a gait parameter (predicted landing position / posture or the like) of the robot1 is corrected as appropriate according to a result of the check, so as to generate a gait of the robot 1. Thus, a desired gait that satisfies a predetermined geometric restrictive condition related to the interference between the robot 1 and an object is generated by reflecting an actual environmental condition in real time while carrying out the operational control of the robot 1.

Output data of a multiplexer 11 is EFM-modulated by an EFM modulator 12. In the EFM modulation, merging bits that satisfy run length limit conditions Tmin=3 and Tmax=11 are selected. Among them, merging bits that converge DSV are selected. A run length controlling portion 13 detects a particular data pattern that causes DSV to increase as large as a data read error takes place and controls the EFM modulator 12 so that the run length limit conditions of the EFM are loosened. As a result, an increase of DSV is suppressed. Data is reproduced from a data recording medium on which the data has been recorded in such a manner and the reproduced data is decoded. The decoded data is re-encoded so as to record it to another recoding medium. When the data pattern is re-encoded, DSV increases. As a result, data cannot be correctly reproduced from the other recording medium. Consequently, a copying operation can be prevented.
