ABSTRACT:
There are provided a data recording medium, a reading device for reading the data recording medium, a recording device for reading the data recording medium and recording data to other media, and methods thereof able to prevent forgery without comparing visible information and data stored in a built-in electronic circuit chip. The reading device is for reading a data recording medium including a sheet portion visibly printed with an image and a data storage unit recorded with control data. The reading device comprises a first reading unit adapted to optically read the image on the sheet portion, a second reading unit adapted to read the control data including read permission data indicating whether reading of the image is permitted, a determination unit adapted to determine whether reading of the image by the first reading unit is permitted based on the read permission data obtained by the second reading unit, and a controller adapted to control the first reading unit based on the determination by the determination unit.
