PROBLEM TO BE SOLVED: To stably reproduce signals by reducing reproduction errors. SOLUTION: An optical disk reproducing device 10 is provided with a clock detector 14 for detecting a clock from the reproducing signal of an optical disk 1, a synchronous detector 16 for detecting a postamble and an address from the reproducing signal of the optical disk 1, and a postamble generator 20. The postamble is a synchronous signal disposed in the last part of a cluster. The postamble generator 20 has a counter therein to count clocks, and always estimates an address based on a counter value. When the synchronous detector 16 detects no postamble, the postamble generator estimates a current address position from the counter value to generate a postamble signal in a predetermined position.
