ABSTRACT:
In a data reproducing apparatus compatibility among plural recording media can be improved. In the data reproducing apparatus, the latest tap coefficient is stored as a tap coefficient in a transversal filter during the normal reproducing operation. This latest tap coefficient is used as an initial value during next reproducing operation. Accordingly, a capture operation for the reproducing operation can be quickly executed. Thus, even when a plurality of recording media are replaced and reproduced in this data reproducing apparatus, a difference between the characteristics of the recording media can be absorbed.
