ABSTRACT:
Recorded data is read by an image sensor from a recording medium on which the data is two-dimensionally recorded in a mesh pattern, and the read data is stored in an image RAM. The stored data is subjected to data decoding and error correction to reproduce target data. A scanning reference pattern of a mesh pattern recorded on the recording medium serves as a guide when the stored recorded data read by the image sensor is reproduced by scanning in the image RAM. A reproduction apparatus has a capability of coping with a partial destruction of the scanning reference pattern. Error checking codes are added to the recording medium in addition to the target data. These items of data are recorded as an encoded image after being subjected to scrambling processing and randomization processing. The reproduction apparatus can easily cope with an error when the encoded image is reproduced.
