摘要：
A pick-up of a format determining apparatus irradiates light to an optical disk to generate a reproduction signal. A signal processing unit decodes the reproduction signal to generate main data. A CD-ROM decoder decodes the main data. A CD-ROM determining unit determines whether or not the main data is in a CD-ROM format, based on the decoded main data. A reproduction signal determining unit determines whether or not the reproduction signal is normal when the main data is not in the CD-ROM format. A system control unit determines that the main data is in a CD-DA format, when the main data is not in the CD-ROM format, and when the reproduction signal is normal.
