ABSTRACT:
A digital signal reproducing apparatus includes an address continuity check circuit, in addition to a parity check circuit, to check the validity of a reproduced block address. The address continuity check circuit checks the address continuity of n consecutively reproduced data blocks. In accordance with the present invention, a reproduced block address will be accepted as a correct block address only when it passes a parity check and a continuity check. Thus, the possibility of failing to detect an incorrect block address is greatly decreased.
