Abstract

Before each content file is recorded first to a recording medium, a flag indicating a recording state of a content file is generated corresponding to a physical area where an index file can be continuously recorded. An index file is generated which associates attribute information with the generated flag added thereto with real data of each content file, and the generated index file is recorded to the recording medium. Since fragmentation of the physical area where the index file is recorded is restrained to a minimum level, a high-speed reading operation is realized.

Description

technical field

[0001] The present invention relates to a recording apparatus and method for recording each content file on a recording medium, and particularly to a recording apparatus and method which generate an index file for each content file to be recorded on a recording medium, and This index file is recorded on the recording medium, wherein the index file associates attribute information assigned to each content file with actual data of each content file.

[0002] This patent application claims priority to Japanese Patent Application 2003-054314 filed on February 28, 2003, the entire contents of which are incorporated herein by reference. Background technique

[0003] In an information processing apparatus such as a personal computer or a PDA (Personal Digital Assistant), a non-linear access hard disk and various recording media such as an optical disk, a magneto-optical disk, and a memory card are loaded, and data is recorded on these media. Also, there has been pr...
