Paper Abstract

We have developed an optical pick up with multi beam laser diode (LD). Multi beam LD has three emitters and individual emitter can control independently. Primary experiment for parallel recording has done and acceptable results for Power Margin, Tilt Margin, Defocus smargin and Detrack margin have measured. After than, possibility of double speed recording has confirmed by dual beam recording method.
