    • PURPOSE: A data recording method is provided to cause a deflection or emission of a DSV(Digital Sum Variation) when a virtual DSV value outputted from a DSV counter is changed to a negative value, and to form the changed DSV value in zigzag shape, thereby recording data without read incapability during a reproduction. CONSTITUTION: By deflecting a DSV in either a positive direction or a negative direction, DSV control data which causes read incapability of data during a reproduction is recorded in at least a portion of a recording area. Specific control data having more than two symbols is disposed behind data where the DSV control data cannot be recorded. By the specific control data, a front bit of a code symbol of the DSV control data right after the specific control data is fixed to '0' or '1', so that the DSV can be deflected in either the positive direction or the negative direction.
    • 目的:提供一种数据记录方法,用于当从DSV计数器输出的虚拟DSV值变为负值时引起DSV(数字和变化)的偏转或发射,并以Z字形形成改变后的DSV值, 从而在再现期间记录数据而不读取无能力。 构成:通过在正方向或负方向上偏转DSV,在再现期间导致数据读取不适用的DSV控制数据被记录在记录区域的至少一部分中。 具有多于两个符号的具体控制数据被布置在不能记录DSV控制数据的数据之后。 通过特定的控制数据,紧接在特定控制数据之后的DSV控制数据的代码符号的前置位被固定为“0”或“1”,使得DSV可以在正方向或负方向偏转 方向。
