Optical disk image drawing method |
摘要 |
<p>An optical disk image drawing method includes: rotating the optical disk by a spindle motor; reading a predetermined information recorded on a track of a data recording layer; detecting a predetermined position on the track based on the read predetermined information; measuring a position of the spindle motor in a rotating direction using the detected predetermined position as a reference position; changing a focus position of the laser beam to the image drawing layer; starting forming the visible image on the image drawing layer from a predetermined position of the spindle motor in the rotating direction relative to the reference position based on the measured position of the spindle motor in the rotating direction; and sequentially moving an optical pick-up in the radial direction synchronously with the rotation of the spindle motor to proceed to form the visible image.</p> |
