摘要:
An optical recording and reproduction method, optical pickup device, and optical recording and reproduction device are provided, in which an optical recording medium is irradiated with near-field light to perform recording and/or reproduction, and wherein two or more recording and reproduction beam spots are positioned in a recording and reproduction area between guide tracks on the optical recording medium to perform recording and/or reproduction, as a consequence of which application to near-field optical recording and reproduction is ideally performed, and high transfer rates become possible.
