Abstract
The present invention provides a recording medium reproducing method comprising the steps of: irradiating light onto a recording medium, the recording medium including a data image and a reference pattern, the reference pattern being divided by a plurality of fractional regions, the fractional regions being in invert, rotational and symmetrical relationship; determining information associated to data-image distortion based on the reference pattern; and correcting position of the data image based on the information relating to data-image distortion.
Claims29
A recording medium reproducing method, comprising the steps of:
- irradiating light onto a recording medium, the recording medium including a data image and a reference pattern image, the reference pattern image being within user data of the data image, the reference pattern image being divided by a plurality of fractional regions, the fractional regions being in an invert and/or rotational and/or symmetrical relationship;
- determining information associated to data-image distortion based on the reference pattern image;
- and
- correcting a position of the data image based on the information associated to data-image distortion.
A recording medium recording method, comprising the steps of:
- inserting a reference pattern image in user data of a data image, the reference pattern image being divided by a plurality of fractional regions, the fractional regions being in an invert and/or rotational and/or symmetrical relationship;
- and
- recording the data image in a recording medium,
- wherein the reference pattern image determines information associated to data-image distortion, and a position of the data image is corrected, based on the information associated to data-image distortion.
A recording medium recording apparatus, comprising:
- a control unit configured to insert a reference pattern image in user data of a data image, the reference pattern image being divided by a plurality of fractional regions, the fractional regions being in an invert and/or rotational and/or symmetrical relationship;
- and
- a light-outputting unit configured to record the data image in a recording medium,
- wherein the reference pattern image determines information associated to data-image distortion, and a position of the data image is corrected based on the information associated to data-image distortion.
