System Outline
HVD(Holographic Versatile Disc) evaluation system,SHOT-2000(Standard Holographic Optical Tester),
developed to record the HVD hologram and evaluates its playback condition based on the ODU-1000(Optical
Disc Unit), the de-fact standard evaluation system for optical discs.

Recording・Playback                         〔Collinear Method〕
Set the laser power and DMD pattern with PC before executing Record/Playback. Then, set the recording position
related items (sector, recording and playback position, and number of overwrite) from HOLOGRAM in ODU menu.
Click “Holographic Write” or “Holographic Read” button to execute. The evaluation is controlled from PC because
the number of overwrite is set to “1”, and the data is input into CMOS. For the shift-multiplexing, the recording is
carried out with variable set-up followed by the playback evaluation. This system records/evaluates the identical
recording position of full one rotational sector(120 sectors) with same DMD pattern, power, and overwrite number.

The plan wave tester, SHOT-500, is an automatic evaluation system for the characteristic of recording
material by two beam interferometry. This system is equipped with the dynamic function to record/
playback the hologram with green laser(532nm) and red laser(633nm) spontaneously. Using the angle
multiplex and peristrophic methods together, this system can evaluate the recording characteristic of
multiplex and large capacity material.
