APPARATUS FOR RECORDING ANGULAR MULTIPLEXED PIT

PROBLEM TO BE SOLVED: To provide an apparatus for recoding angular multiplexed pits on optical recording media using a device (1) for generating a light beam with an asymmetric intensitiy distribution.

SOLUTION: According to the invention, the device (1) for generating a light beam with an asymmetric intensity distribution has at least one light influencing part (3) for introducing a phase shift of 180° in a first half of the light beam relative to the second half of the light beam, wherein the border between the first half of the light beam and the second half of the light beam is rotatable around an optical axis of the light beam.
