Abstract:
1. A recording signal generating apparatus for receiving an information data piece and management data relating to said information data piece to generate a data signal to be recorded on a recording medium, said information data piece comprising a plurality of data cells, said management data including cell reproduction time periods of said plurality of data cells, comprising: a divider for dividing said plurality of data cells into a series of data units in accordance with a predetermined data format; a first calculator for calculating unit start timings for the respective data units, each of the unit start timings representing a time period required for reproduction of data from a head position of said information data piece up to a head position of each of the data units, a second calculator for calculating cell start timings for the respective data cells using the cell reproduction time periods, each of the cell start timings representing a time period required for reproduction of data from a head position of said information data piece up to a head position of each of the data cells, a first modifier for modifying said information data piece by adding each of data pieces which represent the respective unit start timings to the corresponding data unit in accordance with the predetermined data format to generate a modified information data piece; a second modifier for modifying said management data by inserting data representing the cell start timings into said management data in accordance with the predetermined data format to generate modified management data; and a generator for combining said modified information data piece and said modified management data to generate a data signal to be recorded on said recording medium.
