    • A method for discriminating the operation type of a disk device uses an optical head carrying an objective lens. The gravity doesn't affect the control force of the optical head in the horizontal operation type, reduces the control force in a vertical operation type, and increases the control force in inverse operation type. Control forces based on various operation types forms different motion features of the optical head to discriminate the operation type. Damping characteristic parameters of each operation type of the optical head are previously determined by test first. The Control force is transported to the optical head, and the timer is reset. The displacement of the optical head is continuously detected till reaching a predetermined situation. The time of timer is read to compare with the threshold of each operation type for distinguishing the operation type.
    • 用于识别盘装置的操作类型的方法使用携带物镜的光学头。 重力不影响水平操作型光头的控制力,降低了垂直操作型的控制力,增加了反向操作型的控制力。 基于各种操作类型的控制力形成光头的不同运动特征以区分操作类型。 预先通过测试首先确定光头的每种操作类型的阻尼特性参数。 控制力传输到光头,定时器复位。 连续检测光头的位移,直至达到预定的情况。 读取定时器的时间与每种操作类型的阈值进行比较,以区分操作类型。

    • The disclosure discloses a compensation method in a radial direction on a label side of an optical disc. An optical disc is inserted into an optical disk drive. The data side of the optical disc is divided into at least one compensation area. An optical pick-up head (OPU) is moved from inner to outer rings by simulating a writing process. The OPU is moved to some pre-determined points and radial-directional compensation is performed to obtain radial-directional voltage gains at the pre-determined points. The voltage gains are recorded. The label side of an optical disc is inserted into the optical disk drive. The simulated track number is calculated on the basis of the required moving distance for the OPU to write pattern on the label side. The OPU is moved to write the label side by a radial-directional lens driving voltage compensated with a gain obtained from a compensation formula.
    • 本公开公开了在光盘的标签侧的径向的补偿方法。 将光盘插入光盘驱动器。 光盘的数据侧被分成至少一个补偿区域。 通过模拟写入过程,光学拾取头(OPU)从内圈移动到外圈。 将OPU移动到某些预定点,并且执行径向方向补偿以在预定点处获得径向方向的电压增益。 记录电压增益。 将光盘的标签侧插入光盘驱动器。 基于OPU在标签侧写入图案所需的移动距离来计算模拟轨道号。 移动OPU通过用从补偿公式获得的增益补偿的径向方向透镜驱动电压来写入标签侧。

    • A discrimination method of an optical disc. The method includes: focusing a light spot on a rewritable zone of the optical disc; reading an EFM signal of data marks of the optical disc to check if the optical disc is a data disc or a blank disc; when the optical disc is a data disc, utilizing an SBAD signal for discrimination of the optical disc; when the optical disc is a blank disc, utilizing a DPD signal for discrimination of the optical disc; checking if the header signals exist or not; identifying the optical disc as a DVD-RAM disc if the header signals exist; and identifying the optical disc as a DVD-RW disc if there is no header signal. In this way, the accuracy of the optical disc discrimination is enhanced.
