Claims17
An information recording method comprising:
- forming file data and metadata regarding the file data into recording information;
- dividing a recording medium into a plurality of zones if a recording mode is set;
- and
- recording the file data and the metadata in different zones of the plurality of zones.
An information reading method in which file data and metadata are recorded in different zones, the information reading method comprising:
- obtaining the metadata regarding the file data, from a metadata zone;
- detecting a start address and an end address of the file data from the metadata zone;
- setting the detected start address as a start location of the file data in a file data zone;
- and
- reading the file data from the file data zone in predetermined blocks with reference to the set start location of the file data.
An information recording and reading apparatus comprising:
- a recording medium;
- and
- a control unit which divides the recording medium into a plurality of zones when a recording mode is set, recording file data and metadata in different zones of the plurality of zones, and reading the file data from a file data zone in predetermined blocks with reference to a start location of the file data, which is detected from a metadata zone of the recording medium, if a reading mode is set.
