Embodiment 1

[0112] In the recording medium system, in the case where only reproduction of data is allowed under the assumption that the data providing content is recorded thereon, the recording medium system provides the information that can only be reproduced by using user fingerprint information at the time of initial manufacturing of the recording medium and authentication software. Content.

[0113] User fingerprint information is registered in the identity authentication software. In this case, by marking the initial fingerprint on the recording medium, and obtaining user fingerprint information by using an RF signal, the user fingerprint information thus obtained can be recorded on the authenticated software as authenticated information, or can be obtained by using An external device (eg, a fingerprint applicator) obtains and records user fingerprint information.

[0114] In the method for realizing the security given to the recording medium by the recording / reproducing device, if ...

Embodiment 2

[0116] In the case of a recording medium system that allows both data recording / data reproduction, user fingerprint information is registered on the recording medium. In this example, by marking the initial fingerprint on the recording medium, and obtaining the initial fingerprint as the user fingerprint information by using an RF signal, the user fingerprint information can be recorded on the recording medium as identity authentication information, or can be recorded by using an external device ( For example, a fingerprint applicator) obtains and records fingerprint information.

[0117] In addition, user fingerprint information can be recorded on a recording medium or on an external device (eg, a drive, a computer, identity authentication software, etc.).

[0118] The method for realizing the security given to the recording medium by the recording / reproducing apparatus is the same as that of the first embodiment. If the fingerprint is marked on the recording medium, the use...

Abstract

The present invention provides a recording / reproducing method for a recording medium including a data recording layer and a user information recording layer, wherein the recording / reproducing method includes the steps of: receiving inputted user information; determining whether the inputted user information matches the user information recorded on the user information recording layer of the recording medium; and recording data onto the data recording layer of the recording medium, or reproducing data of the data recording layer, in accordance with the result of the determination.

Description

technical field [0001] The present invention relates to a recording medium and a recording / reproducing method and recording / reproducing apparatus for the recording medium. In more detail, the present invention relates to a recording medium capable of ensuring security, and a recording / reproducing method and recording / reproducing apparatus for the recording medium Background technique [0002] Currently, due to the development of various technologies, recording media have reached the level of storing 25 GB per layer. In addition, as long as the drive is provided, everyone can access the recording medium and read data therefrom. [0003] However, due to this accessibility and interchangeability, a weak point has been shown in terms of recording medium security. Anyone can read and copy data from the recording medium, and when the recording medium is discarded, it is inconvenient to completely erase the data from the recording medium. [0004] In the case of distributing a r...
