ABSTRACT:
The present invention provides a disc reproduction apparatus capable of correctly and easily read out a bar code data without carrying out a strictly constant angular velocity control. The disc reproduction apparatus according to the present invention includes a measurement block for measuring an edge interval of a bar code signal extracted from reading a bar code data recording area on a disc and a decoder for using the edge interval values measured by this measurement block, so as to decode the bar code data. This decoder identifies each of the edge interval values with a corresponding bar interval according to a distribution of the edge values measured.
