    摘要: A system for measuring the thickness of one or more layers (32) of an optical disc that includes a spacer layer (32b) and a cover layer (32a) by using an interference effect of an optical disc layer is disclosed. The apparatus comprises a spectroscope (42) to separate light, reflected from a surface of an optical disc, into constituent frequencies, an optical intensity measuring unit (44) to measure intensities of the constituent frequencies, respectively, as a first spectrum of data, and a processor (46). The processor (46) is adapted to do at least the following: convert the first spectrum data into a second spectrum of values that exhibits variation as a function of wavelength and refractive index, transform the second spectrum using a Fast Fourier Transform, and detect a thickness of one or more of the spacer layer (32b) and the cover layer (32a), respectively, based upon the transformed spectrum.
    Moreover, a corresponding device and machine-readable medium are disclosed.

    摘要: A data structure of a control information for use with a recording medium having at least one recording layer. The control information includes at least two information units which include a first information unit for a lower writing speed and a second information unit for a higher writing speed. The first information unit includes write strategy parameters for a first write strategy type to be used for the writing speed. Said first write strategy type is one of a plurality of write strategy types applicable to the same writing speed and recording layer. The second information unit for a higher writing speed includes write strategy parameters for the first write strategy type or a second type to be used for the higher writing speed.
