A recording apparatus such as an optical disk and a file management method are disclosed by which, where an index file is formed from groups of data wherein extract information is collected for different types and one of the groups of data is used to collectively manage the other groups of data, a process relating to deletion or addition of extract information can be executed simply, easily, and with certainty. In each of slots of a property entry, information representing whether the slot is valid or invalid and information representative of a relationship to different slots to which extract information relating to the same file is allocated are recorded, and a combination of the slots in which the extract information of the one file is allocated is managed with the property entry.

An entry property 2 contained in an entry property identifies normal or system. The normal represents an entry of entity data. The system represents an entry which describes a definition of flags. The flags represent attribute information of a file. The flags are defined by an apparatus or a user. An entry property 3 identifies valid or invalid of the entry. An entry property 4 represents whether or not a file registered to the entry references another file. A referred counter represents the number of files referred from another file. When a designated file is referenced from another file, a referring file list represents a file which references the designated file. With these information, a reference relation of files can be described.

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.

There are provided a storage device for outputting data in such a manner that whether or not error correction has been made can be discriminated, and a data processing system in which a storage device furnishes data to a data processing device in such a manner that whether or not the area management information has been corrected for errors can be discriminated and in which the data processing device discriminates whether or not the area management information has been corrected for errors in order to perform predetermined data processing. There is also provided a data processing method for the storage device and for the data processing system. If there is any error correctable by an error processing unit 26 in the area management information read out from the flash memory 21, the controller 27 furnishes the area management information to the error correction processing unit 26 and appends a flag indicating the fact of error correction to the area management information corrected for errors to output the resulting data.
