Apparatus for and method of setting accurate recording time point

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 being pre-recorded on the recording medium at predetermined intervals, locations of the marks corresponding to locations of the predetermined areas, respectively, the locations of the predetermined areas being predetermined on the basis of a time length of the information piece, the method comprising the processes of:

• detecting at least one of the marks;
• generating a expectation signal on the basis of the time length of the information piece and synchronizing a time point at which an output of the expectation signal is started with a time point at which the at least one of the marks is detected in the detecting process, the expectation signal being a signal for determining an expectation time point that one of the marks, except for the at least one of the marks already detected in the detecting process, is to be detected;
• and
• setting the expectation time point determined by the expectation signal as the recording time point,
• wherein the generating process comprises a process of adjusting the expectation time point depending on whether no information piece is recorded on the recording medium or whether another information piece has been already recorded on the recording medium.
