Problems solved by technology

[0008] However, according to the above-mentioned conventional optical disc device, the user must manually input a unique password assigned to the optical disc in advance by the manufacturer, so that it is impossible for the user to freely change the unique password of the optical disc.
In addition, whenever a user wants to reproduce arbitrary data stored in an optical disc, the user must memorize many different passwords assigned to individual optical discs, or must visually verify a unique password for the disc to be played, resulting in a major inconvenience to the user. the inconvenience

Embodiment Construction

[0023] Now, the best mode for carrying out the present invention will be described in detail with reference to the accompanying drawings. In the drawings, the same or similar parts will be denoted by the same reference numerals even if they appear in different drawings. In the following description, when a detailed description of known functions and configurations contained therein makes the subject matter of the present invention unclear, the detailed description of this part will be omitted.

[0024] The password management method according to the present invention can be adapted to optical disc devices, such as figure 1 Shown is a DVD player composed of an optical pickup unit 11, a VDP system 12, a signal synthesizer 13, a memory 14, an OSD generator 15, and the like.

[0025] According to this password management method, the VDP system 12 reads the disc ID (identification) (IDentification) from the navigation information recorded in the lead-in area (or other indication a...

Abstract

The present invention provides a password management method of an optical disc device for recording / reproducing data on an optical disc such as a CD or DVD disc. A method for managing passwords in an optical disc device, comprising the steps of: a) determining whether the current optical disc has been reproduced by the optical disc device before; and b) if the determining step (a) determines that the current optical disc has been reproduced before, The user is then asked to enter the first password specified by the user.

Description

technical field [0001] The present invention relates to an optical device for recording data on an optical disc, such as a CD or DVD, and for reproducing data recorded on the optical disc. Background technique [0002] Recently, there is a newly researched optical disc device capable of recording / reproducing high-quality video data and high-quality audio data that can be stored thereon for a long period of time, for example, a DVD (Digital Versatile Disc) player, so that the optical disc device become more popular as a recording medium. figure 1 A block diagram of a conventional optical disc device is described. Such as figure 1 As shown, the conventional optical disc device includes an optical pickup unit 11 for recording data on the optical disc 10 or reproducing data recorded on the optical disc 10, a VDP (Video Disc Player) (VideoDisc Player) system 12, a synthesizer 13, A memory 14, and an OSD (On-Screen Display) generator 15. [0003] figure 2 is for figure 1 A ...
