HOLOGRAPHY RECORDING SYSTEM AND REPRODUCING DEVICE, METHOD THEREOF, AND HOLOGRAPHY MEDIUM

摘要

PROBLEM TO BE SOLVED: To provide a holography medium, enabling information data stack position detection, usable as a servo signal during movement to another information data stack by detection of the relative position relation between the medium and an optical system in case of their position shift.;SOLUTION: The holography medium of the present invention has position detection information, indicating the position of an information data stack where a plurality of information data pages are recorded while the angle of reference light is changed, recorded in a designated information data page when information data are written.;COPYRIGHT: (C)2006,JPO&NCIPI
