HOLOGRAPHIC MASTER SYSTEM FOR MANUFACTURING A MASTER DISK AND APPARATUS FOR FABRICATING HOLOGRAPHIC ROM DISK USING A MASTER DISK

摘要

and holographic master system according to the present invention is a light source for generating laser light, a laser light reflecting portion and, by transmitting the other part of the light separator for separating the laser light into reference light and signal light, and a first reflecting mirror for reflecting the reference light transmitted through the optical splitter to the first optical path, the first reference light reflected by the reflection mirror and a second reflecting mirror for reflecting at a predetermined angle of incidence, is connected to the second reflective mirror is connected to a rotary actuator and data recording during the power source to change the incident angle of the reference beam by driving the second reflecting mirror, reflected by the optical splitter and a master disk is produced by recording the interference pattern of the reference interference signal gwanggan incident via the second reflecting mirror, and the first shutter for supplying or blocking the signal light reflected by the optical splitter to the master disk, the data is turned on and block the supply to the signal light is the master disk by controlling said first shutter to the case, if the data is on-off control of the first shutter by a control unit such that the signal is supplied to the master disk. ; The present invention is by recording this master disk and the disk for recording the interference pattern is irradiated with the signal light after arranging the disk for recording, the hole making the graphic ROM disk.
