    • PROBLEM TO BE SOLVED: To provide a reproducing system which can make itself more useful. SOLUTION: This audio system 7 checks the user identification data transmitted together with the compressed music data from a portable reproducing device 3. When it recognizes that the user who purchased/downloaded the compressed music data is the same user who owns the audio system 7, it stores the compressed music data after reproducing the music signals from the compressed music data in the decoder 34 and the music data processing section 35. When it recognizes that the user who purchased/downloaded the compressed music data is not the same user who owns the audio system 7, it erases the compressed music data after reproducing the music signals from the compressed music data in the decoder 34 and the music data processing section 35.

    • PROBLEM TO BE SOLVED: To provide an information recording/reproducing device which secures the validity of information recorded on an information recording medium, while achieving both the secure of validity of information and high-speed access, independently of the host computer. SOLUTION: The information recording/reproducing device, which cooperates with the information recording medium having a ROM area and a RAM area, includes: an optical pickup part for reading out the information stored in the information recording medium in which the control information used for limiting the readout and/or writing of the information is recorded in advance on either one area of the ROM area or the RAM area; and a control part for limiting the readout and/or the writing of the information on the other area in which the control information is not recorded and for outputting a signal for notifying of only the existence of the other area, on the basis of the control information read out by the optical pickup part.

    • PROBLEM TO BE SOLVED: To utilize a signal that is recorded on a recording medium and is unique to the recording medium, or to utilize unique reproduction information based on the signal for preventing proper information reproduction operation from being performed in the event of theft.
      SOLUTION: An operation restriction means is provided, which stops the proper reproduction operation for reproduction information based on a signal other than the signal that is recorded on the recording medium fitted to a recording medium fitting section by an information reproduction section and is unique to the recording medium, when preset time passes without newly discriminating the coincidence of the unique signal read by the information reproduction section or the unique reproduction information obtained based on the unique signal with an identification signal stored in a memory means or identification information by a discriminating means, after the discriminating means discriminates the coincidence of the unique signal read by the information reproduction section or the unique reproduction information obtained based on the unique signal with the identification signal stored in the memory means or the identification information.
