Disc recording medium having subsidiary data in which is stored an identifier

Abstract

A disc-shaped recording medium and a reproducing apparatus for the disc-shaped recording medium in which the letter information, such as a title, pertinent to a program recorded on the disc-shaped recording medium, is recorded as subsidiary data in a management area or in a program area. In the subsidiary data, there is recorded an identified for specifying whether or not the subsidiary data is allowed to be duplicated on an other recording medium so that inhibition or permission of duplication of the subsidiary information may be controlled at the time of duplication of the program.

       7. The disc-shaped  recording medium as claimed in  claim 6  wherein the recording medium is made up of a management area and a program area, said management area has the subsidiary data and the management data recorded therein, and wherein the identifier for one of inhibiting and permitting duplication of said subsidiary data is included in the subsidiary data recorded in the management area. 
     
     
       8. The disc-shaped  recording medium as claimed in  claim 6  wherein the recording medium is made up of a management area and a program area, said management area has the subsidiary data and the management data recorded therein, said subsidiary data is recorded along with the main data in said program area, and wherein the identifier for one of inhibiting and permitting duplication of said subsidiary data is included in the subsidiary data recorded in the program area. 
     
     
       9. The disc-shaped  recording medium as claimed in  claim 6  wherein the subsidiary data is the letter information concerning the disc-shaped  recording medium and the program recorded on the disc-shaped  recording medium. 
     
     
       10. The disc-shaped  recording medium as claimed in  claim 6  wherein the main data is audio data and wherein said subsidiary data is at least one of the name of the disc-shaped  recording medium, name of the performer, name of the composer, name of the lyricist, name of the arranger, name of the publisher and date of production. 
     
     
       11. A method for transmitting from a recording medium main data and subsidiary data ancillary to the main data, the method comprising the steps of: 
       
         detecting a flag specifying one of inhibition and permission of digitally outputting the subsidiary data from the recording medium, and  
       
       
         controlling one of inhibition and permission of digitally outputting the subsidiary data in accordance with the detected flag so as to prevent copying of the subsidiary data to another medium.
