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 (1a) to be reproduced by an information reproducing apparatus (S2). The information reproducing apparatus is provided with a read device (80) and reproduces audio information by a predetermined audio frame unit while relatively moving the read device along the record track recorded with at least the audio information by the audio frame unit. A plurality of audio packets (43, 202) are arranged along the record track, in each of which audio information pieces (207) constructing the audio information sampled by a predetermined sampling frequency and audio control information (203) for controlling a reproduction of the audio information pieces by the information reproducing apparatus are respectively recorded. The audio control information is provided with time management information (203f: PTS) for specifying a time, by a predetermined specification frequency, to manage a timing of outputting the audio information, which is included in the audio frame which head is positioned in the audio packet including the audio control information, in the reproduction by the information reproducing apparatus.
