Abstract:
1. An information processing unit comprising: a reading section for reading information recorded in a recording medium; an information processing section for processing the information read by this reading section; a positional instruction recognizing section for recognizing an instruction for a prespecified position in said information; a change instruction recognizing section recognizing a change instruction to change a reproducing position of the information of the information processing section when a rotary operation is detected; a processing control section for changing the reproducing position of the information processing section when the change instruction is recognized by the change instruction recognizing section; and a display section for displaying an instructed position corresponding to the instructed information on a virtual orbit simulating a movement of the recording medium along a rotary operation direction of the change instruction recognizing section when the positional instruction is recognized by said positional instruction recognizing section, wherein the display section provides a prespecified display along said virtual orbit, fixes the instructed position on said virtual orbit, and displays in the moving state a processing position along said virtual orbit, wherein said virtual orbit includes a plurality of concentric virtual orbits, and wherein, when the processing position and the instructed position are away from each other in a direction orthogonal to a circumferential direction of said virtual orbit, said display section displays said processing position and said instructed position in different display forms respectively.
