Abstract:
1. An information recording/reproducing apparatus for recording or reproducing information data to or from a recording medium recorded with a synchronization signal and an address indicating a recording position which are preliminarily modulated, the information recording/reproducing apparatus comprising: a reading unit for reading recorded information from the recording medium and obtaining a readout signal; an error corrector for carrying out an error correction process on the address data and obtaining corrected address data; a synchronization controller for causing the timing pulse generator to execute a synchronization process for placing the generation timing in synchronism with the synchronization signal when the synchronization signal has a period equal to a predetermined period; whereby the synchronization controller, in the case the corrected address data is determined as a correct address, then puts the synchronization process into stand-by for execution until the corrected address data is determined as an incorrect address.
