上記光ディスクのリードインゾーンに記載された情報から上記光ディスクがDVD−ROMである情報を検出した後、上記光ディスクのデータゾーンからトラッキングエラー信号が検出されない場合は、上記データゾーンにおけるウォブル信号を検出し、上記ウォブル信号が検出されたことによりウォブルグルーブが存在する光ディスクであると判断されたときは、上記光ディスクをDVD Download規格のブランクディスクと判定するとともに、上記光ディスクの読み取り動作を停止する、
ことを特徴とする光ディスクの判別方法。 In a method of discriminating an optical disc for discriminating the type of optical disc loaded,
After the optical disk the optical disk from the information described in the lead-in zone detects information is D VD-ROM, when the tracking error signal from the data zone of the optical disk is not detected, detecting a wobble signal in the data zone When it is determined that the wobble groove is present due to the detection of the wobble signal, the optical disk is determined to be a DVD Download standard blank disk and the reading operation of the optical disk is stopped.
A method of discriminating an optical disc characterized by the above.
上記光ディスクのリードインゾーンに記載されている情報から、上記光ディスクがDVD−ROMであることを識別する第一識別手段と、
上記第一識別手段によりDVD−ROMと識別されたときに、位相差方式により上記光ディスクのデータゾーンからトラッキングエラー信号の検出を行う第二識別手段と、
上記第二識別手段によりトラッキングエラー信号が検出されないときは、プッシュプル方式でデータゾーンからウォブル信号を検出する第三識別手段と、
上記第三識別手段でウォブル信号を検出したときは、DVD Download規格のブランクディスクであると判別するとともに、上記光ディスクの読み取り動作を停止する判別手段と
を備えたことを特徴とする光ディスク装置。 An optical disc apparatus for recording and / or reproducing information of a loaded optical disc,
First identification means for identifying from the information described in the lead-in zone of the optical disc that the optical disc is a DVD-ROM;
When identified as by Ri D VD-ROM in the first identifying means, and a second identification means for detecting a tracking error signal from the data zone of the optical disc by the phase difference method,
When the tracking error signal is not detected by the second identification means, the third identification means for detecting the wobble signal from the data zone by the push-pull method,
An optical disc apparatus comprising: a discriminating unit that discriminates that the disc is a DVD Download standard blank disc and stops the reading operation of the optical disc when the third discriminating unit detects a wobble signal.
