ABSTRACT:
A digital signal which is recorded on a recording medium with being encoded is duplicated to another recording medium without being decoded. An audio signal is recorded and/or reproduced using data recorded in a TOG of the recording medium. A first data signal (2-channel audio signal) is intermittently recorded on and/or reproduced from a first area of the recording medium, and a second data signal (other 2-channel audio signal) is intermittently recorded on and/or reproduced from a second area of the recording medium during a period in which the first data signal is not recorded or reproduced.
