ABSTRACT:
A master disk exposure device capable of projecting varying sized laser beams on a master disk, includes a slider for moving an optical fiber in a radial direction along the surface of a master disk. The optical fiber projects a beam emitted by a beam generator. The beam is passed through a shutter intermittently before being focussed by a focus lens once focused the beam is projected by the optical fiber onto the recording surface of the master disk.
