| 摘要 |
An apparatus for optical pickup is disclosed which minimizes offset element occurring between the recorded and non-recorded pattern when object lenses are configured off-axis along the tracks on the optical storage medium. The optical pickup of the present invention minimizes the offset voltage level change by passing the incident beam into the optical storage as one beam and then dividing the beam into three beams and by preventing the AC signal of sub beam from reaching the light detecting means.
