Record carrier, method of recording information on a record carrier, recording apparatus and playback device

Abstract

By this method of recording information on a record carrier an information volume is recorded in sectors of a track ( 10 ) of the record carrier in compliance with the CD-ROM XA standard. The information volume comprises data files (F 1 , . . . , F 6 ) and control information (VD, PT, DF 1 , DF 2 , DF 3 ) intended to be used for controlling the search for information in the recorded information volume. According to the invention the information volume in addition comprises a File Location Table (FLT 2 ) with File Location Entries containing an identification and an address ( 21, . . . , 26 ) of the data files (F 1 , . . . , F 6 ), which File Location Table (FLT 2 ) has a size of at most one sector. This method of recording enables a relatively simple microprocessor to retrieve the information recorded, while maintaining compatibility with the CD-ROM XA standard.

1 . Record carrier on which an information volume is stored in tracks of the record carrier in compliance with a standard, which information volume comprises data files and control information intended to be used for controlling the search for information in the recorded information volume, characterized in that the information volume in addition comprises a File Location Table with File Location Entries containing an identification and an address of the data files.  
     
     
         2 . Record carrier according to  claim 1 , characterized in that the information volume is divided in sectors, the File Location Table having a size of at most one sector.  
     
     
         3 . Record carrier according to  claim 1  or  2 , characterized in that the standard is the ISO-9660 standard.  
     
     
         4 . Record carrier according to  claim 1 ,  2  or  3 , characterized in that the identification is selected from a first and a second range of values, wherein a value in the first range represents a specific one of a series of a first type of file and the values in the second range represent other filetypes.  
     
     
         5 . Record carrier according to one of the previous claims, characterized in that the File Location Entries are stored at locations which are spaced at mutually equal distances, wherein the distance between two succeeding File Location Entries is stored in an entry of the File Location Table.  
     
     
         6 . Method of recording information on a record carrier, in which method an information volume is recorded in tracks of the record carrier in compliance with a standard, which information volume comprises data files and control information intended to be used for controlling the search for information in the recorded information volume, characterized in that the information volume in addition comprises a File Location Table with File Location Entries containing an identification and an address of the data files.  
     
     
         7 . Recording apparatus for recording information comprising data files on a record carrier in compliance with a standard, which apparatus comprises recording means for recording information in tracks of the record carrier, formatting means for composing an information volume in accordance with predetermined formatting instructions, according to which instructions the information volume is provided with control information intended to be used for controlling the search for information in the information volume, and control means for causing the recording means to record the information volume, characterized in that, the apparatus comprises deriving means for deriving a File Location Table with File Location Entries which contain an identification and an address of the data files and in that the control means are arranged for causing the File Location Table to be recorded in addition to the other information.  
     
     
         8 . Playback device for reading a record carrier according to  claim 1 , comprising a processor arranged for processing the File Location Table.
