  • Patent number: 7724409
    Abstract: A system and method for recording and reproducing holographic interferogram with servos. A servo process is provided by the system and method to continuously record a holographic interferogram in a holographic recording medium with servo trace layers. Also, by the servo process, the intensity distribution of a reference beam is monitored, which is reflected by a reflecting mirror disposed on the other side of the holographic recording medium. By analyzing the distribution, one can adjust the distance and the incidence angle between the reflection mirror and the reference beam. Moreover, a plurality of servo tracks on different layers are provided for recording the holographic interferogram on different layers of holographic recording medium.

  • Patent number: 7486592
    Abstract: An optical head to access data on an optical recording medium, which has two data storage densities, includes two sets of optical path systems to provide two optical paths that are crossed. Each optical path system includes a laser light generation unit, a light guiding unit, a converging objective lens and a photo detector. The light guiding unit is located on the optical path of the laser light generation unit, to direct the laser light to pass through the converging objective lens and focus on the data side of the optical recording medium to carry optical data signals from the data side. The laser light returns to the light guiding unit and travels along the optical path and is received by the photo detector.

    Abstract: A system and method for recording and reproducing holographic interferogram with servo is provided. A servo process is provided by the system and method to continuously recording a holographic interferogram in a holographic recording medium with servo trace layers. By the servo process, reproducing signals are captured rapidly and correctly. Also, by the servo process, the intensity distribution of a reference beam is monitored, which is reflected by a reflecting mirror disposed on the other side of the holographic recording medium and transmits the holographic recording medium. By analyzing the distribution, one can adjust the distance and the incidence angle between the reflection mirror and the reference beam. Moreover, a plurality of servo tracks at different layer is provided for recording the holographic interferogram at different layers of holographic recording medium.
