摘要： The invention relates to a method for storing data in a prerecorded area of an optical recording medium, and to an optical recording medium having at least one prerecorded area in which data is stored according to the method.It is an object to propose a method for storing data in a prerecorded area of an optical recording medium using pits (6) and lands ( 7), whereby the signal obtained from the pits ( 6) and lands (7) is compatible with a high frequency modulated groove signal.According to the invention, the pits ( 6) and lands( 7) adjacent to bit cell signal transitions( 1, 2, 3, 4) are arranged in a predefined manner, either in a fixed recurring sequence of pits 6) and lands (7) or symmetrically to the bit cell signal transitions (1, 2, 3, 4).
