Initializer can crystallize optical disc such as Rewritable BD, DVD and CD.


  • High speed initializing by High-Power Semiconductor Laser
  • Applicable for wide variety of discs e.g. Multi Layer Disc, Coverless Disc etc.
  • Possible to select CAV (Constant Angular Velocity) and CLV (Constant Linear Velocity)


What is Initializing

Laser Beam is irradiated from inner side to outside of the disc. Recording Layer can be crystallized from the amorphous status at high speed for initialization of the disc.
