Optical information recording/reproducing device |
摘要 |
A device for recording information on a recordable optical disk includes: an optical pickup provided with laser unit for emitting and irradiating a laser beam onto the optical disk; radial tilt detecting unit for detecting tilt quantity of the optical disk in a radial direction thereof; tangential tilt detecting unit for detecting tilt quantity of the optical disk in a tangential direction thereof; radial tilt correcting mechanism for moving the pickup on the basis of the radial tilt quantity to correct the radial tilt; and tangential tilt correcting unit for controlling the power of the laser beam on the basis of the tangential tilt quantity.
