Definitions
- the hologram recording layer is irradiated with a light beam so as to pass from the hologram recording layer to the reflection function layer, and light is irradiated on a portion of the hologram recording layer where reference light and signal light components of the light beam interfere with each other.
- FIG. 7 is a schematic perspective view schematically showing a three-axis actuator for an objective lens in a pickup of a hologram recording / reproducing apparatus for recording and reproducing information on a hologram record carrier according to an embodiment of the present invention.
- the reflection function layer 5 is made of a second light-sensitive material whose physical property S changes irreversibly in response to the intensity of a service beam SB (second light beam) having a wavelength different from that of the first light beam FB.
- a service beam SB second light beam
- the second photosensitive material for example, a phase change film or a dye film can be used.
- the sensitivity to the wavelength of the service beam SB is set higher than the sensitivity to the wavelength of the first light beam FB.
- Hologram recording by Servo Beam SB Positioning on the hologram record carrier 2 for focusing (focus servo, x, y direction servo).
- the substrate 3 is made of, for example, glass, a poly-polycarbonate, amorphous polyolefin, polyimide, plastic such as PET, PEN, PES, or an ultraviolet curable acrylic resin.
- a group is formed as a plurality of tracks T extending without intersecting at a distance.
- the reflection function layer 5 functions as a guide layer.
- the separation layer 6 and the protective layer 8 are made of a light-transmitting material, and have a function of flattening the laminated structure and protecting the hologram recording layer.
- a pinhole PH that transmits the 0th-order light component of the first light beam FB is formed in the reflection function layer 5.
- a photosensitive material having a characteristic value in which the reflectance at the time of non-irradiation is higher than the reflectance at the time of irradiation (or the transmittance whose characteristic value at the time of non-irradiation is lower than the transmittance at the time of irradiation) is used. Used for reflective function layer 5.
- the non-reflective part is Either it has a high characteristic value transmittance or the non-reflection portion has a characteristic value reflectance lower than the reflectance at the time of non-light irradiation.
- the reflection-type polarization spatial light modulator SLM has the function of electrically reflecting some of the incident light on a liquid crystal panel or the like that has a plurality of pixel electrodes divided in a matrix, or that all of the light is transmitted and is not reflected It has a function to set a state.
- the polarization spatial light modulator SLM is connected to the first light source drive circuit 25a, and the recording light from the spatial light modulator drive circuit 26 (a two-dimensional pattern such as a bright and dark dot pattern on a plane) is to be recorded.
- the light beam is modulated and reflected so as to have a distribution based on the information pattern of the day and night to generate signal light.
- X and y direction movement drive signals are generated, and these are supplied to the X direction movement support circuit 30X and the y direction movement support circuit 30y, respectively.
- the X-direction movement support circuit 30 X and y-direction movement support circuit 30 y drives the objective lens drive unit 36 mounted on the pickup 23 according to the X and y-direction movement drive signals. Therefore, the objective lens is driven by an amount corresponding to the drive current based on the drive signals in the X, y, and z directions, and the position of the light spot applied to the hologram record carrier is displaced. As a result, the hologram formation time can be secured while keeping the relative position of the light spot with respect to the moving hologram record carrier during recording.
- the servo beam SB is set to an optical output capable of piercing the reflection function layer 5, and the pinhole PH is pierced.
- the hologram record carrier 2 is moved in the y direction by an interval P y so that the spot of the first light beam FB matches the pinhole PH.
- the hologram is recorded by the first light beam FB. Since the spot of the first optical beam FB and the spot of the servo beam SB are separated by the distance Py in advance, the spot where the next hologram is recorded can be obtained without moving the hologram record carrier 2 while recording the hologram. Pinhole PH can be pre-drilled.
