ABSTRACT:
An apparatus and a method for detecting address information are provided. The apparatus for detecting address information from an optical disc on which a plurality of sectors are arranged and pre-pit data are recorded on each sector, includes: a window generation circuit for generating a detection window for detecting the pre-pit data; a data detection circuit for detecting the pre-pit data based on the generated detection window; a latch for latching the data detected by the data detection circuit to a larger number of bits than a pre-allotted number of bits; a synch information extraction circuit for generating synch information informing a time to refer to the latched data; and an address information extraction circuit for detecting address information by reading the latched data based on the generated synch information. Therefore, the address information recorded on an optical recording medium as land pre-pit (LPP) data can be efficiently detected.
