Information recording medium and reproducing apparatus therefor
View Patent ↗An environmental load information of an information recording medium is recorded on the information recording medium so as to recycle or dispose properly an information recording medium, which is not necessary any more. The information recording medium comprises a main information area ( 102 ) for recording or reproducing information and a recording area ( 101 ) for environmental load information, which is recorded with an environmental load information of the information recording medium.
1. An information recording medium comprising:
a main information recording area provided for recording or reproducing main information; 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,
wherein said environmental load information is recorded as a letter pattern, and
wherein said product manufacturing information is composed of at least one 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.
2. An information recording medium comprising:
a main information recording area provided for recording or reproducing main information; 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,
wherein said environmental load information is recorded as a letter pattern, and
wherein said product manufacturing information is composed of a name or code representing at least one company from a manufacturing company, a requesting company for manufacturing, and a contents producing company.
3. A reproducing apparatus for reproducing an information recording medium comprising:
a main information recording area provided for recording or reproducing main information; and
a recording area for environmental load information recorded with environmental load information being 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 said recording area for environmental load information is recorded as a letter pattern,
said reproducing apparatus comprising:
a reproducing means for reproducing said main information by a light source having a wavelength of 350 to 550 nm.
4. The reproducing apparatus in accordance with claim 3 , wherein said product manufacturing information is composed of a name or code representing at least one company from a manufacturing company, a requesting company for manufacturing, and a contents producing company.
5. The reproducing apparatus in accordance with claim 3 , wherein said product manufacturing information is composed of at least one 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.
