Abstract

A CPU converts multimedia information, which has been input from a multimedia information input unit, to an optically readable dot code, and prints the dot code on an information recording medium by means of a recording head. In this case, a control unit moves the recording head in a first direction of the information recording medium, and moves the information recording medium and recording head relative to each other in a second direction perpendicular to the first direction. When the dot code, which is spatially independent, is to be recorded on the information recording medium, the CPU controls the control unit such that the dot code is recorded only by a single one-way scan operation of the recording head unit in the first direction, without moving the information recording medium and the recording head unit relative to each other in the second direction.

Claims

1. An information recording apparatus for recording, on an information recording medium, multimedia information including at least one of audio information, image information and digital code data in an optically readable code form, said information recording apparatus comprising:

a recording head unit for printing a code associated with the multimedia information on the information recording medium;

driving means for moving the recording head unit in a first direction of the information recording medium, and for moving the information recording medium relative to the recording head unit in a second direction perpendicular to the first direction; and

layout information input means for inputting layout information according to which the code is printed on the information recording medium,

wherein predetermined processing is executed with respect to the code to be recorded, in accordance with the input layout information, such that the code is recorded on the information recording medium in a spatially independent tanner only by a single one-way scan operation of the recording head unit in the first direction, without moving the information recording medium and the recording head unit relative to each other in the second direction.

2. An information recording apparatus according to claim 1, wherein said layout information includes information relating to a position of the code on the information recording medium, and information relating to a width of the code as measured in the second direction, and wherein said predetermined processing is executed in accordance with the information relating to the position of the code and the information relating to the width of the code.

3. An information recording apparatus according to claim 2, wherein said predetermined processing includes dividing code information into components so as to enable the code to be recorded in a divided fashion.

4. An information recording apparatus according to claim 3, wherein said recording head unit also records identification information which indicates that each of the components is one of a plurality of divided code components constituting the code.

5. An information recording apparatus according to claim 4, wherein said identification information includes a number indicating an order of reading the divided code components.

6. An information recording apparatus according to claim 4, wherein said identification information comprises a frame recorded so as to contain all of the divided code components constituting the code.

7. An information recording apparatus according to claim 3, wherein said predetermined processing includes processing for permitting the divided code components based on information division to be recorded in the second direction.

8. An information recording apparatus according to claim 7, wherein said recording head unit also records a visual quasi-code between the divided code components based on the information division.

9. An information recording apparatus according to claim 2, wherein said predetermined processing includes processing for altering a record position where the code is recorded on the information recording medium.

10. An information recording apparatus according to claim 2, wherein said predetermined processing includes processing for varying a recording length of the code in the first direction.

11. An information recording apparatus according to claim 1, wherein said layout information includes width information relating to a width of the code as measured in the second direction, and wherein said predetermined processing is executed in accordance with the width information.

12. An information recording apparatus according to claim 11, wherein said predetermined processing includes dividing code information into components so as to enable the code to be recorded in a divided fashion.

13. An information recording apparatus according to claim 11, wherein said predetermined processing includes processing for altering a record position where the code is recorded on the information recording medium.

14. An information recording apparatus according to claim 11, wherein said predetermined processing includes processing for varying a recording length of the code in the first direction.

15. An information recording apparatus according to claim 1, wherein said layout information includes area information relating to an area in which the code can be recorded on the information recording medium, and wherein said predetermined processing comprises altering a size of the code to be recorded in accordance with the area information.

16. An information recording apparatus according to claim 15, wherein the size of the code to be recorded is altered in accordance with a type of the information recording medium.

17. An information recording apparatus according to claim 16, further comprising means for determining whether or not the code can be recorded after size alteration based on (i) the size of the code altered in accordance with the area information, and (ii) the type of the information recording medium.

18. An information recording apparatus according to claim 1, wherein the code comprises a set of two-dimensionally arranged separable blocks, and wherein each of the blocks includes at least a data dot pattern formed of dots arranged in accordance with a content of the multimedia information, and an address dot pattern indicating an address arranged in a predetermined relationship with respect to the data dot pattern.

19. An information recording apparatus according to claim 1, wherein said recording head unit comprises a line-type head having a longitudinal direction coinciding with the second direction.
