In the case of recording information in a DVD-R 1R as complying with a DVD video standard, which is configured with including at least of a VTS including a VOBS to be reproduced and VTSI and VMGI for controlling the reproduction of one or plural VTSs, the VTS is recorded in the DVD-R 1R. After the VTS is recorded, the tentative VMGI as the tentative control information corresponding to the recorded VTS to form the VMGI after that and to record this VMGI in the DVD-R 1R. Then, the generated tentative VMGI is recorded in the DVD-R 1R every when the VTS is recorded in the DVD-R 1R.

A recording medium has a first recording area on which recording information is recorded, and a second recording area on which management information for managing the recording information is recorded. The second recording area includes a bit rate recording area for recording a bit rate.

Recording medium, and system and method for recording and reproducing the recording medium

An information storage medium includes: a video zone for recording audio/video information including video information and audio information associated with the video information; an audio zone for recording audio information; first navigation information for a video player which can reproduce the audio/video information; second navigation information for an audio player which can reproduce the audio information in the video zone and the audio information in the audio zone; and third navigation information for a compatible player which can reproduce both the audio/video information and the audio information. The first navigation information, the second navigation information and the third navigation information are recorded separately from each other.

Information storage medium and apparatus for reproducing the same

Information recording is conducted in the form of the simple format. When the simple format is indicated, the recording control data is not recorded in a lead-in area LIA, and after the information to be recorded is recorded in a data recording area DRA, the recording control data is recorded in a recording manager area RMA and a lead-out area LOA, in the data recording area DRA, recording manager area RMA, lead-in area LIA, and lead-out area LOA, which are predetermined according to the standard format. Further, when the finalizing processing is indicated, by recording again the recording control data according to the standard format to the information recording medium in which the information recording is conducted according to the simple format, the information recording medium which can be applied to the common information recording and reproducing apparatus, is easily realized.

Recording and reproducing method of information regarding medium and information recording and reproducing apparatus

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 (T) equal to a required time for reproduction until the head position of each of the cells is reached, and a required time for reproduction (P) of each of the cells in a management data region.

Digital dat recording/reproducing apparatus

A recording medium has a first recording area on which recording information is recorded as a set of recording units, and a second recording area on which control information for controlling the recording information to be recorded on the first recording area is recorded. Identifying information for identifying a management condition of the recording information recorded on the first recording area is also recorded on the second recording area at every recording unit.

Recording medium and system for recording and reproducing the recording medium

An information editing apparatus for editing a reproduction manner of record information which is recorded on an information storage medium and includes at least one picture information, includes: a selecting unit for selecting a partial record information from the record information, the partial record information being part of the record information and including at least one picture information; a designating unit for designating a reproduction timing of the selected partial record information; an extracting unit for extracting the picture information included in the partial record information as a representative picture information indicative of the partial record information; and a recording unit for recording one of the extracted representative picture information and a designation information indicative of a recorded position on the information storage medium of the representative picture information and the designated reproduction timing on the information storage medium as a reproduction control information separately from the record information.

Information editing apparatus and information reproducing apparatus

A recording medium has a first recording area on which multiplexed audio informations are recorded as sets of one or more information units, a second recording area on which control information for controlling recording of the multiplexed audio informations are recorded. The control informations include first information representing the number of sets of information composing the multiplexed audio informations, and second information instructing to record the multiplexed audio informations as a stream.

Recording medium and system for recording and reproducing the recording medium using control information that represents the number of sets of information composing the multiplexed audio information

An information record medium (DVD) has a record track recorded with record information to be reproduced by an information reproducing apparatus (S). The information reproducing apparatus is provided with a read device (), 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 (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 () 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,) different from another portion where the record information is recorded.

Information record medium, apparatus for recording the same and apparatus for reproducing the same

An information storage medium includes: a plurality of unit audio information to be reproduced independently of each other; aggregate audio information each including one or more of the unit audio information; unit attribute information indicating attributes of the unit audio information included in the aggregate audio information; and aggregate attribute information including the unit attribute information corresponding to the aggregate audio information recorded on the storage medium. By referring to the aggregate attribute information, the attributes of all the unit audio information may be readily and quickly obtained.
