Optical information processing apparatus and method |
摘要 |
<p>An optical information processing apparatus and an optical information processing method are provided. The optical information processing method includes steps of: irradiating a reference beam on an optical information recording medium having a plurality of recording regions which are disposed in a track direction to be adjacent to each other so as to enclose a specific recording region and first and second recording regions adjacent to the specific recording region; separating a readout beam reproduced from the specific recording region from the first and second neighborhood readout beams reproduced from the first and second recording regions by using the reference beam; and detecting intensities of the first and second neighborhood readout beams and comparing the intensities of the first and second neighborhood readout beams to calculate an optical information reproducing error.</p> |
