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

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： A desired catch-up time at which reproduction started after a start of recording of input information catches up the recording is set. Recording start time, present time and recording end time are detected. A rate of the reproduction necessary to catch up the recording at the set catch-up time is determined recording start time, present time, and recording end time. The recorded information is reproduced at a determined rate until the set catch-up time.

摘要： An apparatus for playing a composite disk containing separate audio-only and video-plus-audio portions, as well as an ordinary compact disk. It is first detected whether the disk being played is a compact disk or a composite disk, and if the disk is a composite disk, whether the portion presently being played is a region containing only audio data or a region containing a frequency modulated video signal recorded in multiplex form with a digital signal. A reference signal for driving a spindle servo circuit is produced as a fixed frequency signal when the disk is a composite disk or the region of a composite disk being played contains only audio data, and as a variable frequency signal of frequency determined in accordance with the frame sync signal contained in the reproduced signal when a region of a composite disk containing a multiplex-type signal is being reproduced.
