A system using a tape cassette ( 1 ) with a memory ( 4 ) as a recording medium is provided. In the memory ( 4 ) provided in the tape cassette ( 1 ) used in the system, there is formed a storage area where instruction/object information in which an instruction to be executed by a required device is stated in addition to a storage area where management information for managing recording to or playback from the tape cassette ( 1 ) is stated. At an information processor ( 10, 40 or 50 ), instruction/object information is acquired from the memory ( 4 ) and processed to provide a control corresponding to the content of the instruction/object information. A device to make some action on the tape cassette ( 1 ) can thus have a higher operability and extensibility.
