Optical recording medium and method of manufacturing same

A method of manufacturing an optical recording medium, comprising the steps of:

• fabricating a first recording member comprising a first substrate having a first information area and a second recording member comprising a second substrate having a second information area by respective injection-molding processes;
• forming a reflecting surface on said second information area of said second substrate;
• and
• joining said first recording member and said second recording member to each other with a transparent layer interposed therebetween with the first and second information areas facing each other.

A method of manufacturing an optical recording medium, comprising the steps of:

• separately fabricating a first recording member having a first light-transmissive substrate and a first semi-light-transmissive information area disposed on a surface of said first light-transmissive substrate, and a second recording member having a second substrate and a second reflective information area disposed on a surface of said second substrate;
• and
• joining said first recording member and said second recording member to each other with a transparent layer interposed therebetween with the first and second information areas facing each other,
• wherein said transparent layer is directly adhered to said first and second information areas.

• and
• joining said first recording member and said second recording member to each other with a transparent layer interposed therebetween with the first and second information areas facing each other,
• wherein said first information area has a reflectance ranging from about 20% to about 50%, and a transmittance ranging from about 30% to about 80%, and said second information area has a reflectance of about 60% or higher.

• joining said first recording member and said second recording member to each other with a transparent layer interposed therebetween with the first and second information areas facing each other;
• and
• recording information in said first and second information areas, whereby said information is progressively recorded in said first information area as said optical recording medium is rotated in a first direction, and said information is progressively recorded in said first information area as said optical recording medium is rotated in said first direction.
