Abstract
An optical recording medium which has an enhanced appearance or an enhanced design performance while computer data are recorded and a reproduction apparatus and method in which the optical recording medium is used are disclosed. When computer data are recorded on the optical recording medium on which recording data are recorded as interference fringes formed through interference of object light of images with reference light, related information of the recording data is recorded in a state wherein it can be recognized through the visual sense of the user.
Claims20
An optical recording medium including data recorded thereon as interference fringes, the interference fringes expressed as interference object light of images obtained for individual recording units from the recorded data relative to reference light, comprising:
- a recording region in which recorded data of a first form is recorded, recorded data of the first form being functional computer data;
- and
- another recording region in which recorded data of a second form is recorded, the recorded data of the second form being visually recognizable image data recorded to said optical recording medium to be perceptible to a visual sense of a human being.
A reproduction apparatus for reproducing an optical recording medium including data recorded thereto as interference fringes, the interference fringes expressed as interference object light of images obtained for individual recording units from the recorded data relative to reference light, the optical recording medium including recorded data of a first form being functional computer data and recorded data of a second form being visually recognizable image data recorded to said optical recording medium to be perceptible to a visual sense of a human being, comprising:
- reference light outputting means for outputting reading out reference light;
- detection means for detecting reproduction images of individual recording units recorded on the optical recording medium while the reading out reference light is applied to the optical recording medium by said reference light outputting means;
- and
- reproduction processing means for converting the reproduction images of the individual recording units detected by said detection means into a data string and for extracting only the data of the first form from the data string and processing the extracted data as reproduction data.
A reproduction method for reproducing an optical recording medium including data recorded thereto as interference fringes, the interference fringes expressed as interference object light of images obtained for individual recording units from the recorded data relative to reference light, the optical recording medium including recorded data of a first form being functional computer data and recorded data of a second form being visually recognizable image data recorded to said optical recording medium to be perceptible to a visual sense of a human being, comprised:
- detecting, at a reproduction apparatus, reproduction images of individual recording units recorded on the optical recording medium while reading out reference light is applied to the optical recording medium;
- and
- converting, at the reproduction apparatus, the reproduction images of the individual recording units detected by the detection step into a data string and for extracting only the data of the first form from the data string and processing the extracted data as reproduction data.
A reproduction apparatus for reproducing an optical recording medium including data recorded thereto as interference fringes, the interference fringes expressed as interference object light of images obtained for individual recording units from the recorded data relative to reference light, the optical recording medium including recorded data of a first form being functional computer data and recorded data of a second form being visually recognizable image data recorded to said optical recording medium to be perceptible to a visual sense of a human being, comprising:
- a reference light outputting unit configured to output reading out reference light;
- a detection unit configured to detect reproduction images of individual recording units recorded on the optical recording medium while the reading out reference light is applied to the optical recording medium by said reference light outputting unit;
- and
- a reproduction processing unit configured to convert the reproduction images of the individual recording units detected by said detection unit into a data string and for extracting only the data of the first form from the data string and processing the extracted data as reproduction data.
