A digital data recording/reproducing apparatus which divides each of information data pieces into a plurality of cells, further divides each of the cells into a series of a plurality of units, and records the units. The digital data recording/reproducing apparatus has means for recording a required time for reproduction until the head position of a unit is reached, with reference to the head position of an information data cell to which a cell belongs, as a unit start time, in addition to each of the units, and means for recording a cell start time (Ts) equal to a required time for reproduction until the head position of each of the cells is reached, and a required time for reproduction (Ps) of each of the cells in a management data region.
A digital data recording/reproducing apparatus for dividing each of information data pieces into a plurality of segments to sequentially record said segments in an information data region on a recording medium, additionally recording a plurality of management data corresponding to each of one or a plurality of information data groups each including one or a plurality of said information data pieces, in a management data region on said recording medium, and reproducing said information data pieces on the basis of said management data, said digital data recording/reproducing apparatus comprising:

1. Field of the Invention
The present invention relates generally to a digital data recording/reproducing apparatus, and more particularly to a digital data recording/reproducing apparatus for recording/reproducing digital data compressed in accordance with a variable bit rate encoding scheme.
2. Description of Related Background Art
FIG. 1 is a block diagram illustrating the configuration of a digital data recording/reproducing apparatus according to the present invention;
FIG. 2 is a schematic diagram for explaining the structure of data which is recorded on a disk;
FIG. 3 is a schematic diagram for explaining the structure of data and time information which are recorded on a disk according to the present invention;
An embodiment of the present invention will hereinafter be described in detail with reference to the accompanying drawings.
FIG. 1 illustrates the configuration of a digital data recording/reproducing apparatus according to the present invention.
The digital data recording/reproducing apparatus in FIG. 1 is provided with an analog audio signal and video signal, for example, from a television tuner or the like as a source. An input audio signal is converted to a digital form by an A/D converter 2, and supplied to an audio encoder 3, while a video signal is converted to a digital form by an A/D converter 4 and supplied to a video encoder 5.
