New applications for content using the copyright protection function of such semiconductor recording media continue to emerge. Users can rip content from music CDs purchased by the user, and can download content from the Internet. More specifically, using a personal computer connected to the Internet, users can purchase and download music, books, and other copyrighted content from on-line content providers, record the downloaded content to a semiconductor recording medium, and can listen to the music or read the book using the semiconductor recording medium and a compact semiconductor player.
In addition to using a personal computer connected to the Internet, users can also purchase content through electronic terminals (digital kiosks) installed in specific fixed locations such as convenience stores, other types of businesses, and even train stations. Because such applications are particularly convenient for the user and afford an expanded sales network for the providers, the type of content and the user environment continue to evolve.
Various recording standards based on the type of semiconductor recording medium and the type of content have been defined for recording copyrighted content to semiconductor recording media, and the recording device records the content according to the standard. This enables any device conforming to the standard to read and write content to the semiconductor recording medium.
Using a music application program by way of example, the content of a song is encrypted using an encryption key, and the key and the encrypted content are stored to the semiconductor recording medium.
Patent reference 2 teaches a semiconductor recording medium for storing a plurality of encryption keys in a predetermined order in a protected memory area that can only be accessed by mutual authentication of the semiconductor recording medium and the host device, and storing encrypted content and corresponding management information in an unprotected memory area. This semiconductor recording medium protects music content from unauthorized decryption (decoding) while still enabling changing the play-back sequence of individual tracks and deleting selected tracks, and thus affords great convenience.

 New applications for message using the copyright protection affair of such semiconductor recording media cover to emerge. Users can rend content from music CDs purchased by the user, and can download content from the Internet. More specifically, using a personal computer get in touch to the Internet, users can purchase and download music, books, and early copyrighted content from on - note content supplier, record the downloaded content to a semiconductor recording medium, and can heed to the music or read the book using the semiconductor recording medium and a compact semiconductor device musician. 
 In addition to using a personal computer connected to the Internet, users can also purchase content through electronic terminals (digital booth) install in specific fixed location such as public toilet stores, other types of business, and even train stations. Because such applications are particularly commodious for the user and afford an expanded sales network for the providers, the type of content and the user environment continue to evolve. 
 Various recording criterion establish on the type of semiconductor recording medium and the type of content have been specify for recording copyrighted content to semiconductor recording media, and the recording device records the content according to the criterion. This enables any device conforming to the standard to read and write message to the semiconductor recording culture medium. 
 Using a music lotion program by way of case, the content of a song is code using an encryption key, and the key and the encrypted content are stored to the semiconductor recording medium. 
 Patent reference 2 teaches a semiconductor recording culture medium for storing a plurality of encoding keys in a predetermined order in a protected memory area that can only be accessed by reciprocal authentication of the semiconductor recording medium and the host device, and storing encrypted content and comparable management information in an unprotected memory area. This semiconductor device recording metier protects music content from unauthorized decryption (decoding) while still enable changing the play - back sequence of individual tracks and deleting selected tracks, and thus affords bang-up convenience.
