摘要:
The present invention relates to a recording apparatus and a record medium for recording a data read time, a seek time, a successive reproduction time, a successive record length, and a correlation among data pieces. A recording apparatus of the present invention is a recoding apparatus for recording data to a rewritable record medium, comprising an encoding means for encoding the data corresponding to a predetermined compressing and encoding system, a converting means for converting a data structure of encoded data that is output from the encoding means into a file structure that a computer software program that synchronously reproduces a moving picture and so forth can handle without need to use a special hardware device, and a recording means for recording data having the file structure to the record medium, wherein the file structure has a first data unit, a second data unit, and a data portion, the second data unit being a set of a plurality of first data units, the data portion describing management information, wherein the plurality of second data units is correlated with a successive record length of the record medium, and wherein the data portion contains a time length and a data length of the second data unit recorded in the successive record length.
摘要:
A digital recording apparatus using a disc shaped record medium including an extracting unit that extracts outlined information of each of a plurality of files recorded on the disc shaped record medium. A correlating unit correlates the extracted outlined information and the plurality of files and generates an index file. A recording unit records the index file to a predetermined position of the disc shaped record medium. When a predetermined operation mode is performed, a plurality of types of data of the plurality of files are output in a predetermined format.
