ABSTRACT:
An optical disc reproduction apparatus is disclosed including a device for detecting a maximum audio signal level recorded on the optical disc. A first course-search is effected of the entire optical disc to detect a first location on the optical disc in which a maximum value of a recorded audio signal is located. A second fine-search of the optical disc is effected within a region extending in opposite directions from the location on the optical disc detected during the first course-search. During the second fine-search operation, a second location on the optical disc is located in which a maximum value of the recorded audio signal level is located. Then, audio signals are reproduced repetitiously in the vicinity of the second location detected during the second fine-search operation.
