    • The present invention relates to an optical system for performing radial tracking on an associated optical record carrier. The optical system contains at least one radiation-emitting device capable of emitting at least three beams: a first beam for reading and/or recording information, and at least a second beam and a third beam for tracking. The optical system is adapted for radial tracking of the first spot from a tracking error signal generated based on the high-frequency component of the central-aperture signal of the second and third beams. The tracking error signal may be generated based on a difference signal of a DC-level of the power of the high-frequency components of the central-aperture signal.

    • In conventional one-dimensional optical storage systems, the data is arranged in a linear fashion, and the format is read out by a single spot. A two-dimensional encoded disc is different, because the data is arranged in a two-dimensional manner (bits are on a bit lattice) and the data is read out by multiple spots. It is important to know the relative intensity of the read-out spots, because the intersymbol interference is used in the signal processing of the reflected signals, and the present invention provides a way of calibrating the relative intensities by placing one or more mirror sections (150) in a non user-data area of an optical record carrier (1) and using the signals reflected therefrom to determine the relative intensities and enable the required accurate calibration of the relative intensities. In one exemplary embodiment, a mirror section (15) is located in the lead-in area (2) of the record carrier (1) in addition to a plurality of broad meta-tracks containing calibration patterns (152).
    • 在传统的一维光存储系统中,数据以线性方式布置,并且格式由单个点读出。 二维编码盘是不同的,因为数据以二维方式排列(位在位格上),数据被多个点读出。 由于在反射信号的信号处理中使用符号间干扰,所以知道读出光斑的相对强度是重要的,本发明通过放置一个或多个镜面部分提供校准相对强度的方法( 150)在光学记录载体(1)的非用户数据区域中并且使用从其反射的信号来确定相对强度并且使得能够对相对强度进行所需的精确校准。 在一个示例性实施例中,除了包含校准图案(152)的多个宽元音轨之外,镜部分(15)还位于记录载体(1)的引入区域(2)中。
