Multi-layer rotary recording medium and recording / reproducing method and apparatus thereof |
摘要 |
A recording method includes a reading step of detecting a reflection light from a recording layer to which a recording is to be made and converting the detected light into a read signal; a detecting step of detecting a position of a preformatted area of a recording layer which the optical beam transmits therethrough other than the recording layer to which a recording is to be made; and a correcting step of correcting intensity of an irradiation light beam or a reproduced signal on the basis of the read signal and the preformatted area position. An apparatus for carrying out the recording method is also provided.
