Abstract
In the reproduction of data from one of N-frame sectors of an optical disk, data marks representing the front ends of the respective frames of a desired sector are detected and counted. When the number of the data marks is more than a predetermined value M (1<M.ltoreq.N), the reproduced data is accepted. Hence, the data accuracy can be ensured and the operating reliability of a data reproducing apparatus can be improved.
