| The optical disc device has a circuit 4 which forms a focus error signal FER for focus servo control based on reflection light from an optical disc exposed to laser light. A data processing unit 2 can control by feedback a position to which an objective lens is moved by a focusing actuator 30 based on the focus error signal. In label printing, the data processing unit controls, by feedforward, a position to which the objective lens is moved by the focusing actuator based on control data for label printing. The operation resolution of the focusing actuator in feedforward control is made higher than that in feedback control. Thus, an intended position control accuracy is achieved in feedforward control. For instance, in feedforward control, the gain of the driver circuit 40 for the focusing actuator is switched to a smaller one in comparison to that in feedback control. | ||||||

| レーザ光が放射された光ディスクからの反射光に基づいてフォーカスサーボ用のフォーカス誤差信号FERを形成する回路4を有する。フォーカス誤差信号に基づいてフォーカシングアクチェータ30による対物レンズの移動位置をフィードバック制御可能なデータ処理ユニット2を有する。ラベル印刷を行うときデータ処理ユニットは、ラベル印刷用制御データに基づいてフォーカシングアクチェータによる対物レンズの移動位置をフィードフォワードで制御する。フィードバック制御におけるフォーカシングアクチェータの動作分解能に比べてフィードフォワード制御におけるフォーカシングアクチェータの動作分解能を高くする。これにより、フィードフォワード制御において所期の位置制御精度を得る。例えばフィードフォワード制御を行うときフォーカシングアクチェータのドライバ回路40に対してフィードバック制御の時よりもゲインを小さく切り換える。 | ||||||

| Disclosed are techniques and systems for manufacturing an optical disc having a stochastic (i.e., non-deterministic) anti-piracy feature in the form of a multi-spiral structure, and for verifying the feature on the optical disc to authenticate the disc for playback. The multi-spiral structure may be comprised of multiple partially interleaved, and partially overlapping, spiral data tracks formed in a designated area of the optical disc. A process of forming the multi-spiral structure may include forming, in the designated area, a first spiral data track with first track pitch and a second spiral data track with second track pitch that is different than the first track pitch. The multi-spiral structure may be analyzed to determine verification parameters for verifying the multi-spiral structure, and those verification parameters may be encrypted so that they may be subsequently decrypted and used to verify the multi-spiral structure on a disc reading device. | ||||||
