ABSTRACT:
An information recording and/or reproducing apparatus reproduces a pre-recorded address information from a recording medium when recording and/or reproducing a main information signal on and/or from the recording medium, where the address information is pre-recorded on substantially parallel tracks of the recording medium with a predetermined period. The information recording and/or reproducing apparatus comprises a first circuit for producing a reproduced signal by scanning one track on the recording medium, a second circuit for generating an address interval signal having a predetermined level during a time corresponding to an interval in which the address information is pre-recorded on the recording medium, and a third circuit for passing the reproduced signal from the first circuit only during the predetermined level of the address interval signal so as to obtain only the address information reproduced from the one track.
