Abstract
A recording time point setting method and apparatus are provided. The recording time point setting method is a method of setting a recording time point for recording an information piece into one of a plurality of predetermined areas on a recording medium on the basis of a plurality of marks. The marks are pre-recorded on the recording medium at predetermined intervals. The locations of the marks correspond to the locations of the predetermined areas, respectively. The locations of the predetermined areas are predetermined on the basis of a time length of the information piece. In this method, firstly, at least one of the marks is detected. Then, an expectation signal is generated on the basis of the time length of the information piece, and then, a time point at which an output of the expectation signal is started is synchronized with a time point at which the at least one of the marks is detected. The expectation signal is a signal for determining an expectation time point that one of the marks, except for the at least one of the marks already detected, is to be detected. Next, the expectation time point determined by the expectation signal is set as the recording time point.
