An information recording medium suitable for optical discs such as DVD-RAM is
provided for integrated management of data as objects in different kinds of AV
formats. Also, an apparatus is provided for data recording and playing to the medium.
The medium stores management information including program chain information (PGC
information) defining the playback order of the objects, and object information
containing information relevant to the objects. The object information has general
information of the object, attribute information and a map associating a playback
time point of the object with an address on the optical disc of a component of
the object to be played. The PGC information has cell information including information
about type of object, identification information. The order of the cell information
in the PGC information corresponds to the order in which the objects are played back.
