• and
• a fourth recording device for recording a disc information file for storing title information, wherein (i) the title information is control information so as to reproduce the plurality of content informations as a title which is the logically united information unit, (ii) the title information specifies one or a plurality of the first information and (iii) the title information acts as a part of reproduction control information to control the reproduction of the content information, wherein
• some of the plurality of content informations are different from each other in reproduction functions required for an information reproduction system to reproduce the plurality of content informations and are adapted to at least partially construct title which is a logically united information unit,
• a reproduction sequence of said some of the plurality of content informations are defined by the plurality of play list informations indicated by one of the first informations,
• each play item information specifies each of a plurality of object information,
• all of the plurality of content informations are packetized and are stored in one object data file,
• all of the object informations are not packetized and are stored in one object information file,
• all of the plurality of play list informations are not packetized and are stored in one play list information file.

An information record method, which is performed by an information record apparatus, comprising:

• a first record process of recording a plurality of content informations, wherein (i) the plurality of content informations being made of a transport stream, (ii-1) the transport stream includes a plurality of partial streams and (ii-2) the transport stream is multiplexed by an aligned unit, (iii-1) the aligned unit comprises a plurality of source packets, (iii-2) a head portion of the aligned unit corresponds to a head portion of the source packets and (iii-3) the aligned unit does not start from a management information packet, (iv) one source packet includes one transport packet, (v) one of the plurality of partial streams is one of a video stream, an audio stream or a sub-picture stream, (vi), each of the plurality of partial streams being multiplexed by the source a packet, (vii) the source packet being a physically accessible source packet and (viii) each transport packet stores pieces of one of video information in the video stream, audio information in the audio stream or sub-picture information in the sub-picture stream;
• a second record process of recording a plurality of first informations, wherein (i-1) each of the plurality of first informations is not multiplexed by the packet and (i-2) each of the plurality of first information indicates a plurality of play list informations, (ii-1) each of the plurality of play list informations includes a plurality of play item informations and (ii-2) each of the plurality of play list informations indicates (ii-2-1) a number of the play item information, (ii-2-2) a number of sub path information and (ii-2-3) a type of sub path which indicates presentation type of sub Path, (iii-1) each of the plurality of play item informations defining a reproduction sequence of one part of the plurality of content informations by a unit of an item, (iii-2) each of the plurality of play item informations is only control information for controlling the reproduction of the entity information and (iii-3) each of the plurality of play item informations indicates start time and end time of one part of the plurality of content informations by a unit of the item, (iv) each of the plurality of sub path informations defines sub-picture information which is reproduced with the content information defined by the play item information, (v) one content information can be shared by the plurality of play item informations;
