Data recording device, data recording method, and computer program

Abstract

A method for initializing a recording medium, on which data is recorded in compliance with the AVCHD standard, is proposed. Under a root directory of partitions, an ICB and FIDs for each directory contained in a directory structure defined by the AVCHD standard are recorded with consideration of information on child directories. Thereafter, an SBD and a metadata bitmap file are recorded in a partition and also, an LVIS is recorded on the basis of information, such as the number of sectors used as a result of recording the ICBs and the FIDs of all the directories and the total number of directories.

Description

technical field [0001] The present invention relates to a data recording device for recording data on a recording medium, a data recording method and a computer program. For example, the present invention relates to a data recording apparatus for recording content such as an AV stream shot using a video camera on a recording medium, a data recording method, and a computer program. [0002] More particularly, the present invention relates to a data recording apparatus for recording data on a recording medium conforming to AVCHD (Advanced Video Coding High Definition), to a data recording method and a computer program, and particularly to a method for storing and managing user data files. A data recording device that records information files together in a predetermined directory relates to a data recording method and a computer program. Background technique [0003] Disc-type recording media (hereinafter referred to as "optical discs"), from which optical reading is performe...
