Document Type and Number:
Japanese Patent JP4321469
Kind Code:
B2
Abstract:
An optical disk recording apparatus includes a beam emitting unit operable to emit a first beam for irradiating a track on an optical disk so as to record data and second and third beams for irradiating spaces between the track and tracks on both sides of the track, respectively; a light detection mechanism operable to detect the first to third beams reflected from the optical disk; a tracking controller operable to control tracking of the first beam on the basis of results of the reflected first to third beams detected by the light detection mechanism; and a determination unit operable to determine whether the first beam records data on a white portion of the track or overwrites data on a recorded portion of the track based on changes in reflected light amounts of the second and third beams detected by the light detection mechanism.
