a main information recording area provided for recording or reproducing; and
a recording area for environmental load information recorded with environmental load information at least composed of product manufacturing information related to said information recording medium,
said main information recording area and said recording area for environmental load information being formed without overlapping each other, and
wherein both said main information recording area and said recording area for environmental load information are recorded in a format being reproduced by a light source having a wavelength of 350 to 550 nm.
2. The information recording medium in accordance with claim 1 , wherein said product manufacturing information is composed of at least information from a name of an intermediate while manufacturing said information recording medium, a name of material used in a manufacturing process, and a coefficient of contaminating environment.
3. The information recording medium in accordance with claim 1 , wherein said product manufacturing information is composed of a name or code representing at least a manufacturing company, a requesting company for manufacturing, or a contents producing company.
4. A reproducing apparatus for reproducing an information recording medium comprising:
a main information recording area provided for recording or reproducing; and
