An information signal reproducing apparatus comprises a memory for storing encoded digital data and error correction data, and a decoder for decoding the digital data, producing decoded digital data organized in blocks, and delivering the decoded digital data one block at a time. A data transmission controller controls the transmission of the digital data from the memory to the decoder, and an analog signal processor forms a reproduced analog information signal in accordance with each block of the decoded digital data. A data supply controller controls the supply of each block of the decoded digital data to the analog signal processor. An operation controller includes a first control for controlling the operation of the data transmission controller and the data supply controller so as to cause the decoder to perform trial decoding of the digital data, and a second control for controlling the operation of the data transmission controller and the data supply controller so as to cause the decoder to perform actual decoding of the digital data after the trail decoding is completed.
