Abstract
A data processor compatible for use with a CD and a DVD includes a first modulation circuit for modulating recording data for recording on a CD to generate first modulated data. A second modulation circuit modulates recording data for recording on a DVD to generate second modulated data. A write signal generation circuit generates a first write signal, which is written to the CD, from the first modulated data, and a second write signal, which is written to the DVD, from the second modulated data. The write signal generation circuit is commonly used for the CD and the DVD to reduce the circuit area of the data processor.
