Definitions

  • the detachable storage media refer to storage media the manufacture and distribution of which are independently performed and which must be combined with a player for use, so that data can be input and output.
  • Such detachable storage media may be classified into a tape type (cassette tape, etc.), a disk type (CD, etc.), and a semiconductor type (memory card, etc.), and into an erasable type and a non-erasable type.
  • DRM Digital Rights Management
  • the digital content is distributed in the state of being stored in a storage medium, such as a CD or DVD.
  • the price of the storage medium is determined depending on the price of digital content, rather than the price of the storage medium itself. Accordingly, for example, the end user of digital musical content must pay for all pieces of music stored in a music CD, even if the end user desires to purchase only one piece of music, therefore there is a problem in that the user's selectivity is considerably limited.
  • erasable and writable storage media for example, a rewritable CD, DVD and semiconductor- type storage medium (memory card, etc.), are distributed and purchased with digital content not stored thereon but in an empty state.
  • the streaming scheme has a characteristic in that it cannot be used off-line, the downloading scheme has a tendency toward increased size of digital content, and the off-line scheme based on storage media has a problem in that it cannot accommodate users' diversifying demands because it fails to take into account the development of technology based on the popularization of compression techniques and it restricts users' right to be selective.
  • the convention digital content acquisition methods require improvement.
  • a further object of the present invention is to provide a method of using a storage medium in which deletable digital content has been previously stored, such that an end user can maintain the stored digital content if the end user desires to use the content, and can freely delete the content if the end user determines the content to be unnecessary, and a method of using a player that is equipped with the storage medium.
  • Still another object of the present invention is to provide a storage medium in which deletable digital content has been stored, which allows the playing of the digital content through a predetermined authentication procedure so as to prevent the illegal reproduction, distribution and use of the digital content, a player equipped with the storage medium, and methods of using the storage medium and the player.
  • the third invention of the present invention provides a digital content player comprising a fixed storage medium, an input/output part for inputting and outputting data in conjunction with the fixed storage medium, a player part for displaying digital content data input by the input/output part, and a processing part for managing digital content stored in the fixed storage medium, wherein the fixed storage medium is the storage medium, which is set forth in claim 2 and in which deletable digital content has been stored.

That is, the coupling part 111 is a part for mechanical coupling, and may refer to the inner circular part of a disk-type storage medium, such as a CD, that acts as a rotating and supporting part, or the metallic part of a USB semiconductor-type storage medium that is connected to the USB terminal of the player 200.
  • the storage media 100, 101 and 400 must be erasable media. Accordingly, storage media on which deletion and rewriting cannot be performed, such as Compact Disk (CD) Read-Only Memory (ROM) and Digital Versatile Disk (DVD) ROM, cannot be considered. Furthermore, since the digital content must be delectably stored, the case where the digital content is stored in ROM and cannot be deleted using a general method is not considered.
