A recording medium and a recording apparatus for storing manufacturer information for supporting specific functions for each manufacturer and a method therefor. A reproducing apparatus for reproducing manufacturer information for supporting specific functions and a method therefor is also provided. If a recording apparatus modifies the contents of the recording medium, then it should record its manufacturer's identification code. A recording apparatus/reproducing apparatus should check the identification code on the recording medium before using its own manufacture information item for some specific function. Also, it is possible to reduce the time required to determine whether the manufacturer information items are effective.

A recording medium for storing information for still pictures, and a recording/reproducing method and apparatus therefor, stores data for a plurality of still pictures and audio data added thereto in one file or a space having a logically one-dimensional order, rather than in each file, and still picture group information for separating the still picture data into a predetermined maximum number of groups in order to manage the still pictures at a group level. The still picture group information includes general information for still picture groups, and information for still pictures in each still picture group. The general information for each still picture group includes the start position of a first still picture in each still picture group, and the information for still pictures in each still picture group includes the sizes of video data and audio data for each still picture.

A recording medium for storing information for still pictures, and a recording and/or reproducing method and apparatus therefor. A writeable and rewriteable recording medium stores data for a plurality of still pictures and audio data added thereto in one file or a space having a logically one-dimensional order, rather than in each file, and still picture group information for separating the still picture data into within a predetermined maximum number of groups in order to manage the still pictures at a group level is then stored on the recording medium. Thus, large-capacity still picture data and audio data added thereto can be recorded and/or reproduced using a minimum amount of information. The still picture group information includes general information for still picture groups, and information for still pictures in each still picture group. The general information for each still picture group includes the start position of a first still picture in each still picture group (the start position of each still picture group). The information for still pictures in each still picture group includes the sizes of video data and audio data for each still picture. Therefore, effective management of information is allowed.

A recordable and/or rewriteable recording medium for storing still picture data, and recording and/or reproducing method and apparatus therefor. The recording medium stores still picture group information for grouping a plurality of still pictures in order to manage the still picture at a group level, and stores audio group information for grouping additional audio data added to the still picture data after the still picture data are recorded. Therefore, large-capacity still picture data and additional audio data added thereto can be recorded using a minimum amount of management information. Further, during reproduction, data can be displayed and edited in units of the respective still pictures. Also, it is possible to cope with after-recording of the audio data.

A recording medium for storing virtual deletion information, and recording and/or reproducing method and apparatus therefor are provided. The recording medium includes a first region having a plurality of pictures, and a second region having first virtual deletion information for the still pictures, and still picture group information for separating the still pictures in the first region into a predetermined maximum number of groups in order to manage the still pictures at a group level, wherein the first virtual deletion information is within the still picture group information, and if the first virtual deletion information is set to a virtual delete state, the corresponding still picture is not to be reproduced. Accordingly, file extent information can be prevented from excessively increasing by maximally preventing a recording area from being scattered, when some of a data file are deleted by a user's request.

摘要:
An apparatus and method for recording and reproducing audio and video data in real time on a rewritable optical disk, and a disk recording medium allowing a user to access recorded data at predetermined intervals. The disk recording medium includes cells having part of predetermined data and set as reproduction and recording units, and information on a position from the start of the cells to a specific position. The method includes forming a cell of part of the recorded audio and video data, forming a program of the one or more cells, forming a part of title (PTT) of a specific portion of the recorded audio and video data, and then forming the information on the cell, the program, and the PTT on the disk.
