Abstract
An apparatus for issuing a recording medium recorded with digitally coded signals, is provided with a data processor for dividing digital data into a plurality of blocks, multiplexing the blocks and arranging multiplexed blocks in predetermined combination patterns, and a printer for recording on the recording medium, as the digitally coded signals, the multiplexed blocks arranged in the predetermined combination patterns and received from the data processor.
Claims23
An apparatus for issuing a recording medium recorded with digitally coded signals, comprising:
- processing means for dividing digital data into a plurality of blocks consisting solely of said digital data, multiplexing each of the blocks and arranging multiplexed blocks in predetermined combination patterns formed of rows and columns which extend in mutually perpendicular directions, so that identical information is arranged in different ways in each of the rows and each of the columns;
- and
- recording means, coupled to said processing means, for recording the digitally coded signals on the recording medium, the digitally coded signals being made up solely of the multiplexed blocks arranged in the predetermined combination patterns and received from said processing means.
An apparatus for reading digitally coded signals from a recording medium, comprising:
- reading means for reading the digitally coded signals from the recording medium, the digitally coded signals being made up solely of digital data which are divided into a plurality of blocks consisting solely of said digital data and each of the blocks is multiplexed so that multiplexed blocks are arranged in predetermined combination patterns formed of rows and columns which extend in mutually perpendicular directions, so that identical information is arranged in different ways in each of the rows and each of the columns;
- and
- processing means, coupled to said reading means, for reproducing the digital data from the digitally coded signals received from the reading means by extracting the blocks and rearranging the extracted blocks.
A recording medium comprising:
- a data region;
- and
- digitally coded signals recorded in said data region, wherein said digitally coded signals are made up solely of digital data which are divided into a plurality of blocks consisting solely of said digital data and each of the blocks is multiplexed so that the multiplexed blocks are arranged in predetermined combination patterns formed of rows and columns which extend in mutually perpendicular directions, so that identical information is arranged in different ways in each of the rows and each of the columns.
An apparatus for reading information from a recording medium, comprising:
- a reading unit to read digitally coded signals from the recording medium corresponding to data that has been divided into a plurality of blocks consisting solely of said information that are each multiplexed and arranged in predetermined combination patterns extending in different directions with identical information arranged differently in each substantially continuous linear arrangement of the blocks;
- and
- a processing unit to extract blocks from the read digitally coded signals corresponding to the data using more than one of the predetermined combination patterns and rearranging the extracted blocks to reproduce the data.
An apparatus for issuing a recording medium having data recorded thereon, comprising:
- a processing unit to divide the data into a plurality of blocks consisting solely of said data and to multiplex each of the blocks and arrange the multiplexed blocks in predetermined combination patterns extending in different directions with identical information arranged differently in each substantially continuous linear arrangement of the blocks, to form digitally coded signals;
- and
- a recording unit to record the digitally coded signals from the processing unit onto the recording medium so that data contents of blocks corresponding to the data is located in more than one of the predetermined combination patterns of the blocks.
An apparatus for recording data onto and reading data from a recording medium, comprising:
- a processing unit to divide the data into a plurality of blocks consisting solely of said data and to multiplex each of the blocks and arrange the multiplexed blocks in predetermined combination patterns extending in different directions with identical information arranged differently in each substantially continuous linear arrangement of the blocks, to form digitally coded signals;
- a recording unit to record the digitally coded signals onto the recording medium;
- and
- a reading unit to read the recorded digitally coded signals from the recording medium, extract specific blocks corresponding to the data, and rearrange the extracted blocks to reproduce the data, wherein data contents of the specific blocks corresponding to the data is read from blocks other than the specific blocks in response to the specific blocks not being read.
