PURPOSE: To perform conversion processing between a first address and a second address, efficiently and at a high speed. CONSTITUTION: When recording and reproducing an information signal in response to a request from a host device, the address conversion of the first address defined by time-axis information and the second address defined by continuous binary digits is performed reciprocally (S82). At this time, the address conversion processing is performed to the highest value in the time-axis information of the first address and the value of the second address, using the conversion table.
