ABSTRACT:
A laser array provides multiple closely spaced light beams. These light beams are reflected off of an optical recording medium. A faceted prism is used to separate the closely spaced beams sets for detection by an optical detector array and detector circuit. The detector circuit provides data, power, tracking and focus signals.
