Abstract:
1. A method of distinguishing a target optical recording medium and a reference optical recording medium having dye layers for recording, comprising: reading a media ID and other attribute data including conditions for recording recorded in a lead-in-area, Land pre-pit (LPP), or Address in pre-groove (ADIP) of the reference optical recording medium, said conditions for recording including laser output for recording and pulse conditions for recording; reading a media ID and other attribute data including conditions for recording recorded in a lead-in area, LPP, or ADIP of the target optical recording medium, said conditions for recording including laser output for recording and pulse conditions for recording; comparing the media ID and each item of the other attribute data of the reference optical recording medium item by item with the media ID and each item of the other attribute data of the target optical recording medium; displaying results of the comparison on a monitor; and if the media ID of the reference optical recording medium matches that of the target optical recording medium, but any item of the other attribute data of the reference optical recording medium does not match the corresponding item of the other attribute data of the target optical recording medium, judging that the dye layers of the target optical recording medium and the reference optical recording medium are different, thereby distinguishing the target optical recording medium and the reference optical recording medium.
