Abstract
An information recording medium includes a plurality of modulated data areas for recording a plurality of modulated codes; and a plurality of SYNC code areas for recording a plurality of SYNC codes. Data other than the plurality of modulated codes is recorded in at least one of the plurality of SYNC code areas in the form of at least one SYNC code.
Claims10
