Dot-code recording method and dot-code recording and reproducing apparatus

Claim 2

A dot-code recording method comprising the steps of: generating a plurality of one-block dot patterns, each said one-block dot pattern comprising a plurality of dots; arranging the plurality of one-block dot patterns to represent multimedia information; distributing a specific range of the plurality of one-block dot patterns according to specific rules to thereby arrange the one-block dot patterns within the specific range in non-time sequence; and recording the non-time sequence distributed one-block dot patterns on a recording medium, wherein, when distributing the one-block dot patterns to arrange the one-block dot patterns within the specific range in non-time sequence, the one-block dot patterns are distributed among a predetermined number of blocks which are only a part of a plurality of blocks composing a dot code to be arranged in non-time sequence.

Claim 3

A dot-code recording method according to claim 1, further comprising the step of distributing the dots in each of the one-block dot patterns to thereby arrange the dots in each of the one-block dot patterns in non-time sequence.

Claim 4

A dot-code recording method according to claim 2, wherein the step of distributing the plurality of one-block dot patterns among the predetermined number of blocks which are a part of the plurality of blocks composing the dot code is carried out after the step of distributing the dots in each of the one-block dot patterns.

Claim 5

A dot-code recording method according to claim 1, wherein the specific range comprises one of: (i) a same column of the one-block dot patterns, (ii) a same row of the one-block dot patterns, and (iii) a range of the one-block dot patterns in a direction perpendicular to a reading direction.

Claim 6

A dot-code recording method according to claim 1, wherein each of the one-block dot patterns is provided with specific address data.

Claim 7

A dot-code recording apparatus comprising: block generating means for generating a plurality of one-block dot patterns, each said one-block dot pattern comprising a plurality of dots; block arranging means for arranging the plurality of one-block dot patterns to represent multimedia information; block distributing means for distributing a specific range of the plurality of one-block dot patterns according to specific rules to thereby arrange the one-block dot patterns within the specific range in non-time sequence; and recording means for recording the non-time sequence distributed one-block dot patterns on a recording medium, wherein, when said block distributing means distributes the one-block dot patterns to arrange the one-block dot patterns within the specific range in non-time sequence, said block distributing means distributes the one-block dot patterns among a predetermined number of blocks which are only a part of a plurality of blocks composing a dot code.

Claim 8

A dot-code recording apparatus comprising: block generating means for generating a plurality of one-block dot patterns, each said one-block dot pattern comprising a plurality of dots; block arranging means for arranging the plurality of one-block dot patterns to represent multimedia information; block distributing means for distributing a specific range of the plurality of one-block dot patterns according to specific rules to thereby arrange the one-block dot patterns within the specific range in non-time sequence; and recording means for recording the non-time sequence distributed one-block dot patterns on a recording medium, wherein, when said block distributing means distributes the one-block dot patterns to arrange the one-block dot patterns within the specific range in non-time sequence, said block distributing means distributes the one-block dot patterns among a predetermined number of blocks which are only a part of a plurality of blocks composing a dot code.

Claim 9

A dot-code reproducing apparatus comprising: reading means for optically reading a dot code recorded on a recording medium, said dot code comprising a plurality of one-block dot patterns, each said one-block dot patterns comprising a plurality of dots, and said one-block dot patterns being distributed according to specific rules in a specific range to thereby be arranged in non-time sequence; block rearranging means for rearranging the one-block dot patterns of the dot code read by the reading means in units of the specific range; and output means for outputting the rearranged one-block dot patterns, wherein, when the one-block dot patterns within the specific range of said dot code are arranged in non-time sequence, the one-block dot patterns are distributed among a predetermined number of blocks composing the dot code, and wherein the block rearranging means rearranges the one-block dot patterns among the predetermined number of blocks which are only a part of the plurality of blocks composing the dot code.

Claim 10

A dot-code reproducing apparatus comprising: reading means for optically reading a dot code recorded on a recording medium, said dot code comprising a plurality of one-block dot patterns, each said one-block dot patterns comprising a plurality of dots, and said one-block dot patterns being distributed according to specific rules in a specific range to thereby be arranged in non-time sequence; block rearranging means for rearranging the one-block dot patterns of the dot code read by the reading means in units of the specific range; and output means for outputting the rearranged one-block dot patterns, wherein, when the one-block dot patterns within the specific range of said dot code are arranged in non-time sequence, the one-block dot patterns are distributed among a predetermined number of blocks composing the dot code, and wherein the block rearranging means rearranges the one-block dot patterns among the predetermined number of blocks which are only a part of the plurality of blocks composing the dot code.
