Abstract
An information reproducing apparatus has (1) a reference signal generating circuit for generating a first reference signal corresponding to reproduced signal of the main information; (2) a first switching circuit for selecting one of the reproduced signal and the first reference signal; and (3) a controller, which generates a selection instructing signal, for controlling such that the reproduced signal is selected during reproducing of the main information recorded area while the first reference signal is selected during reproducing of the main information unrecorded area. With the arrangement, when the main information unrecorded area is reproduced, the clock for carrying out the reproducing of main information is synchronized with the first reference signal which corresponds to the reproduced signal. So, when the reproducing area is changed from the main information unrecorded area to the main information recorded area, the synchronizing with the reproduced signal is carried out in a short time, thereby improving the reliability of the reproducing process.
