摘要： An information record medium (1: DVD) has a record track recorded with video information (42, 44) and audio information (43) to be reproduced by a reproducing apparatus (S2). The reproducing apparatus is provided with a read device (80), performs a normal reproduction while relatively moving the read device along the record track and performs a special reproduction, such as a search, a scan and the like, by moving the read device across the record track on the basis of access information to access the video and audio informations. The video and audio informations and control information (41, 51: DSI) comprising the access information are recorded on the record track such that the video, audio and control informations are divided into a plurality of first data group (30: VOBU), each of which is a minimum unit able to be physically accessed, and are divided into a plurality of second data groups (20: CELL), each of which is a unit able to be logically divided in the normal and special reproductions and comprises a series of the first data groups arranged along the record track. Management information (11, PGCI) including a plurality of first reproduction prohibit informations (202), each of which indicates a prohibition of the special reproduction of respective one of the second data groups, is collectively recorded at one portion of the record track.

摘要： An information record medium (1: DVD) has a record track recorded with record information to be reproduced by an information reproducing apparatus (S2). The information reproducing apparatus is provided with a read device (80), and performs a reproduction while moving the read device along the record track at a predetermined reading linear velocity. The record information is divided into a plurality of first data groups (30: VOBU), each of which is a unit able to be accessed by the information reproducing apparatus, recorded on the record track. Lowest reading rate information (212) indicates a minimum requirement of a reading rate for the information reproducing apparatus to reproduce a reproduction unit, which comprises at least one of the first data groups and which is to be reproduced by the information reproducing apparatus such that a sequential logical meaning of the reproduction unit is continuous. The lowest reading rate information is recorded on the record track at one portion (LI, 11, 41) different from another portion where the record information is recorded.

摘要： An information record medium (1: DVD) has a record track recorded with record information to be reproduced by an information reproducing apparatus (S2). The information reproducing apparatus is provided with a read device (80), and performs a reproduction while moving the read device along the record track at a predetermined reading linear velocity. The record information is divided into a plurality of first data groups (30: VOBU), each of which is a unit able to be accessed by the information reproducing apparatus, recorded on the record track. Lowest reading rate information (212) indicates a minimum requirement of a reading rate for the information reproducing apparatus to reproduce a reproduction unit, which comprises at least one of the first data groups and which is to be reproduced by the information reproducing apparatus such that a sequential logical meaning of the reproduction unit is continuous. The lowest reading rate information is recorded on the record track at one portion (LI, 11, 41) different from another portion where the record information is recorded.
