Optical disc initialization apparatus and method

摘要

An optical disc initialization apparatus includes a table on which an optical disc is placed. The table is guided on a base for linear motion and is moved back and forth by an electric motor. A light source and an optical system are disposed above the table. The light source consists of a plurality of semiconductor laser arrays, each including a plurality of emitters arranged in a row and each emitting a laser beam. The optical system introduces the laser beams from the light source and forms an elongated elliptical laser spot on the optical disc. The major axis of the elliptical laser spot has a length substantially equal to the diameter of a recording area of the optical disc. The table is moved linearly under the optical system in order to initialize the entire recording area of the optical disc through a single scanning operation.
